History has a peculiar habit of giving credit to the person who crosses the finish line while forgetting the person who pointed out where the race was being held in the first place.

We remember Charles Darwin for revolutionizing biology, Winston Churchill for rallying Britain during World War II, and Albert Einstein for making the rest of us feel inadequate whenever someone mentions anything related to physics. We celebrate their achievements, study their biographies, and put their faces on everything from postage stamps to coffee mugs. But behind these famous names are other people whose contributions rarely make it into the history books.

Some were teachers. Others were ministers, professors, friends, or simply people who happened to be in the right place at the right time. They recognized potential, provided encouragement, shared an important idea, or opened a door that the future celebrity might otherwise never have noticed.

Most never became household names themselves. Their protégés, on the other hand, helped change the world.

Here are ten largely forgotten people whose influence helped shape some of history’s most recognizable figures. The stories of these unsung people who changed history offer a reminder that being influential does not necessarily require becoming famous. Sometimes, it merely requires making an impression on someone who eventually does.

1. Edward Kimball: The Sunday School Teacher Who Found a Famous Evangelist in a Shoe Store

In 1855, an 18-year-old named Dwight Moody was selling shoes in Boston. He had received relatively little formal education and was working in his uncle’s business. His immediate prospects had considerably more to do with footwear than with international evangelism.

One of Moody’s Sunday school teachers, Edward Kimball, believed the young salesman needed a deeper personal faith. Rather than wait for Moody to reach this conclusion on his own, Kimball decided to visit him at work.

On April 21, 1855, Kimball entered the Holton shoe store and found Moody in the stockroom. There, surrounded by merchandise rather than a church congregation, he spoke with the young man about Christianity. The conversation helped lead to Moody’s conversion, and he eventually abandoned his commercial ambitions and devoted himself to Christian ministry.

Moody went on to become one of the nineteenth century’s best-known evangelists, conducting enormous revival campaigns in the United States and Britain. He also helped establish the Moody Bible Institute in 1886, although much of the credit for bringing that institution into existence belongs to educator Emma Dryer. Evidently, even a man whose career began with someone else’s encouragement could benefit from another person’s determination to turn a good idea into reality.

Kimball, meanwhile, remained largely what he had been when the story began: a Sunday school teacher. His most consequential contribution to history was not a sermon delivered to thousands, but a conversation with one young man in the back of a shoe store.

It raises an interesting question about how many important events began because someone decided to have an awkward conversation rather than minding his own business.

2. Mordecai Ham: The Evangelist Who Helped Change Billy Graham’s Life

Nearly eighty years later, another future evangelist was waiting for just the right person to speak into his life. In November 1934, a fifteen-year-old North Carolina farm boy attended a series of revival meetings in Charlotte. He had no particular ambition to become a world-famous evangelist, and there was little to suggest that his name would someday be recognized by presidents, royalty, and millions of people around the globe.

His name was Billy Graham. The preacher was a Kentucky-born evangelist named Mordecai Fowler Ham.

Ham had been conducting revival campaigns throughout the American South for years. His preaching was forceful, confrontational, and occasionally controversial. He was not the sort of fellow who delivered a quiet, reassuring message and then invited everyone to enjoy refreshments in the fellowship hall. When Ham believed something was wrong, his audiences generally had little difficulty figuring out what it was.

During his Charlotte campaign, Ham’s preaching made a profound impression on young Graham. Although Graham had grown up in a churchgoing family, he later described the experience as the moment he made a deliberate personal commitment to Christianity.

On November 1, 1934, Graham went forward during the invitation and made the decision that became a defining moment in his spiritual life.

Graham subsequently became one of the most influential Christian evangelists of the twentieth century. Through his preaching campaigns, broadcasts, and publications, he reached audiences around the world and became a spiritual adviser to numerous American presidents.

Ham continued his own evangelistic ministry, but his name never achieved anything approaching Graham’s worldwide recognition. Today, countless people know who Billy Graham was without knowing the name of the preacher whose sermon helped change his life.

It’s a rather impressive legacy for a man who probably had no idea that one of the teenagers in his audience would eventually preach to more people than almost anyone in history.

3. Mordecai Wyatt Johnson: The Minister Who Introduced Martin Luther King Jr. to Gandhi’s Philosophy

Apparently, anyone named Mordecai who delivered a compelling sermon during the first half of the twentieth century had a reasonable chance of influencing a future American icon.

In 1950, a young theology student named Martin Luther King Jr. attended a lecture-sermon at Fellowship House in Philadelphia. The speaker was Mordecai Wyatt Johnson, a Baptist minister and president of Howard University.

Unlike Ham, whose influence on Billy Graham was primarily religious, Johnson was about to introduce King to an idea that would become central to his public career.

Johnson had visited India and was deeply impressed by Mohandas Gandhi’s philosophy of nonviolent resistance. During his Philadelphia address, he explained Gandhi’s approach to social change and the possibilities of confronting injustice without resorting to violence.

King was captivated.

King later remembered Johnson’s address as so powerful that he immediately went out and purchased several books about Gandhi.

King had already developed an interest in Christian ethics and social justice, and he was not entirely unfamiliar with Gandhi. Johnson did not invent King’s concern for racial equality, nor was he the only person who shaped King’s philosophy. What Johnson accomplished was to inspire King to study Gandhi’s ideas seriously and recognize their potential as a practical method of social reform. The young theologian began to see how the Christian command to love one’s enemies might be applied not merely to personal relationships but to organized resistance against injustice.

Within a few years, King would become the most recognizable leader of the American civil rights movement. Nonviolent resistance would be central to the Montgomery bus boycott, the Birmingham campaign, the March on Washington, and numerous other defining moments of the struggle for racial equality.

Johnson himself was no insignificant figure. He had become Howard University’s first African American president in 1926 and was an accomplished educator, minister, and public intellectual. Nevertheless, his name is far less familiar to the general public than that of the young man who listened to him in Philadelphia.

One sermon helped introduce a future Nobel Peace Prize recipient to the strategy that would define his leadership. For a preacher, that is a fairly respectable outcome from an afternoon’s work.

4. Peter Böhler: The Young Missionary Who Helped Transform John Wesley’s Understanding of Faith

John Wesley is remembered as one of the founders of Methodism, a religious movement that eventually influenced millions of Christians around the world. But before becoming the energetic preacher associated with the Methodist revival, Wesley was a troubled Anglican clergyman who had recently returned from a disappointing missionary experience in colonial Georgia.

He had gone to America intending to help convert others and returned deeply uncertain about his own spiritual condition. That is not ordinarily the sort of outcome missionary organizations feature prominently in their recruiting brochures.

In February 1738, Wesley met Peter Böhler, a young German minister associated with the Moravian Church. Böhler was only twenty-five years old and was preparing for missionary work in America. Despite being younger than Wesley, he became an important spiritual adviser to the struggling English clergyman.

During their conversations, Böhler emphasized salvation through faith and the possibility of personal assurance of God’s grace. Wesley, who had spent years pursuing religious discipline and good works, struggled with the implications.

When Wesley wondered whether he should stop preaching until he possessed the kind of faith Böhler described, his younger adviser offered a characteristically direct response: “Preach faith till you have it.”

On May 24, 1738, Wesley attended a meeting on Aldersgate Street in London, where he experienced the famous spiritual awakening that he described as having his heart “strangely warmed.” Böhler was not present to manufacture the experience, but his earlier conversations had helped prepare Wesley to understand it.

Wesley subsequently emerged as a central figure in the evangelical revival and the development of Methodism. His influence extended far beyond what eventually became the United Methodist Church, shaping denominations such as the African Methodist Episcopal Church, African Methodist Episcopal Zion Church, Christian Methodist Episcopal Church, Free Methodist Church, and Wesleyan Church. His teachings on grace, sanctification, and holy living also helped inspire the broader Holiness movement, including the Church of the Nazarene and the Salvation Army, as well as important branches of the Pentecostal movement. Not bad for an Anglican priest who originally had no intention of establishing a new denomination, much less an entire family tree of them.

Böhler continued his missionary work and eventually became a Moravian bishop. Yet outside specialized church history circles, he is little remembered.

There is something wonderfully ironic about a young missionary traveling to America who, before leaving England, helped redirect the spiritual life of a man whose influence would reach far beyond either country.

5. William Bourke Cockran: The American Politician Who Taught Winston Churchill the Power of Words

Winston Churchill is remembered for his speeches almost as much as for his leadership during World War II. His words helped sustain British morale during some of the darkest moments of the twentieth century, demonstrating that an exceptionally well-constructed sentence could accomplish nearly as much as an exceptionally well-positioned army.

But Churchill was not born delivering magnificent speeches about blood, toil, tears, and sweat. Like every great speaker, he developed his skills by studying others.

One of his most important influences was William Bourke Cockran, an Irish-born American lawyer, politician, and celebrated public speaker.

Churchill met Cockran during his first visit to the United States in 1895, when the future prime minister was just twenty years old. Cockran welcomed the young visitor into his New York home, introduced him to influential Americans, and engaged him in extensive conversations about politics and public affairs.

Cockran was already famous for his commanding oratory. His speeches combined elaborate language, carefully constructed arguments, rhetorical contrasts, and a remarkable ability to hold an audience’s attention.

Churchill absorbed the lessons.

Cockran became an important mentor whose example helped shape Churchill’s political thinking and speaking style. Churchill later expressed extraordinary admiration for Cockran’s conversational abilities.

Of course, Churchill possessed considerable natural talent of his own. He also studied his father’s speeches, read voraciously, and spent years practicing his craft. Cockran’s importance was not that he gave Churchill a voice, but that he provided an especially powerful model for how that voice might be used.

Churchill eventually became one of history’s most celebrated speakers, inspiring Britain through the Blitz and helping shape the language of wartime resistance.

Cockran served multiple terms in the United States House of Representatives and enjoyed a distinguished legal career, but his fame largely faded after his death. His rhetorical legacy, however, lived on in the speeches of the young Englishman he had entertained in New York.

As we have previously observed in our examination of Churchill’s insistence on concise writing, the prime minister understood the importance of carefully chosen words. He also understood that sometimes the most effective way to learn an important skill is to watch someone who already knows how to do it.

6. John Stevens Henslow: The Professor Who Helped Put Charles Darwin Aboard the HMS Beagle

In 1831, Charles Darwin was a young Cambridge graduate whose future was anything but settled. He had abandoned medical studies at Edinburgh and was considering a career in the Church of England. His enthusiasm for collecting beetles and studying nature was considerably greater than his enthusiasm for becoming a physician.

Fortunately for science, Darwin had developed a close relationship with John Stevens Henslow, a Cambridge professor of botany and an Anglican clergyman.

Henslow encouraged Darwin’s interest in natural history, welcomed him into academic discussions, and helped develop his skills as an observer. He recognized that the young man possessed unusual curiosity and a willingness to undertake painstaking scientific work.

Then came an unexpected opportunity.

Captain Robert FitzRoy was preparing for a surveying expedition aboard HMS Beagle and wanted a gentleman naturalist to accompany him. Cambridge mathematician George Peacock helped search for a suitable candidate, with both Henslow and naturalist Leonard Jenyns considered before attention turned to Darwin. On August 24, 1831, Henslow wrote to Darwin recommending that he seize the opportunity. He explained that FitzRoy wanted someone who would be an agreeable companion as well as a capable scientific observer. Henslow believed Darwin possessed precisely those qualifications, even though the young man was not yet an accomplished professional naturalist.

The voyage lasted almost five years, from 1831 to 1836. During that time, Darwin studied geological formations, collected specimens, and made observations that eventually contributed to his development of the theory of evolution by natural selection.

His experiences were not the sole source of his theory, which developed through years of subsequent research and reflection. Nevertheless, the voyage was among the most consequential opportunities of his scientific career.

Henslow did more than recommend his former student. He also maintained contact with Darwin during the voyage and helped bring his scientific observations and specimens to the attention of scholars back in Britain. Darwin later acknowledged his considerable debt to Henslow, recognizing the professor’s encouragement as a major influence on his development as a naturalist.

Today, Darwin’s name is inseparable from modern biology. Henslow’s is primarily familiar to historians of science and botanists.

One might reasonably argue that a professor’s recommendation letter helped change the course of scientific history. It certainly beats the usual academic recommendation that the applicant was punctual, pleasant, and unlikely to set fire to the laboratory.

Incidentally, Darwin’s own travels produced several unexpected connections, including his use of observations by the remarkable blind explorer James Holman, whose adventures we have explored elsewhere.

7. Dikran Tahta: The Mathematics Teacher Who Inspired Stephen Hawking

Stephen Hawking became one of the world’s most recognizable scientists, exploring black holes, cosmology, and the origins of the universe. He occupied a prestigious mathematics professorship at Cambridge University and became an international celebrity whose books introduced millions of readers to questions they previously had not realized were so difficult.

But before he became a scientific superstar, Hawking was a schoolboy at St Albans School in England, where he encountered a mathematics teacher named Dikran Tahta.

Tahta, often known as Dick, possessed an unusual enthusiasm for mathematics and an equally unusual ability to communicate that enthusiasm to students. Rather than treating mathematics as an endless procession of equations designed to destroy childhood happiness, he presented it as a fascinating system for understanding the universe.

Hawking was captivated.

Tahta’s classes encouraged questions, debate, experimentation, and creative problem-solving. He also worked with Hawking and other students on the construction of an early computer using electromechanical switches.

The machine was hardly a modern laptop. It was, however, an extraordinary project for schoolboys during the 1950s, especially when most computers occupied entire rooms and were not generally available for completing one’s mathematics homework.

Decades later, Hawking publicly honored Tahta during a campaign celebrating outstanding teachers. In his tribute, he credited the teacher with opening his eyes to mathematics as a way of understanding the universe.

Hawking specifically credited Tahta with helping set him on the path toward becoming a mathematics professor at Cambridge, a position once held by Isaac Newton.

Tahta himself became a respected mathematics educator, writing about teaching methods and encouraging generations of teachers to make mathematics more engaging. He never became a global celebrity, but he helped inspire someone who eventually explained black holes to the rest of us.

Considering the intellectual difficulty of Hawking’s work, simply persuading a teenager that mathematics was enjoyable may have been the most impressive achievement of all.

8. Max Talmey: The Medical Student Who Gave Albert Einstein Something Worth Reading

Albert Einstein is perhaps history’s most recognizable symbol of intelligence. His name has become practically synonymous with genius, and his face has appeared on countless posters, advertisements, and novelty products intended to suggest that the purchaser is unusually clever.

Yet even Einstein benefited from someone who recognized his intellectual curiosity and helped feed it.

That person was Max Talmey, a young medical student whose original surname was Talmud.

In 1889, when Einstein was about ten years old, Talmey began visiting the Einstein family in Munich for regular meals. The arrangement reflected a Jewish custom of welcoming a student into the household, although the family’s particular tradition involved a Thursday dinner rather than the more familiar Sabbath gathering.

The young Albert and his older visitor soon discovered a shared enthusiasm for scientific questions. Talmey began bringing books on mathematics, physics, and philosophy, introducing Einstein to subjects far beyond those ordinarily taught to children his age.

Among the works he recommended were popular scientific writings by Aaron Bernstein, which explored contemporary discoveries and encouraged readers to think about the natural world in new ways. He also encouraged Einstein’s study of geometry. The young Einstein became fascinated by the elegance of mathematical proofs and the possibility of discovering certainty through logical reasoning.

Eventually, Einstein’s mathematical abilities exceeded the medical student’s capacity to teach him. One imagines this was simultaneously gratifying and slightly irritating. Most tutors hope their students will excel, but preferably not before the tutor has finished explaining the chapter.

Talmey eventually became an ophthalmologist and pursued his own intellectual interests, including writing about Einstein’s theories.

His influence also provides a useful corrective to one of the most persistent legends surrounding the great physicist. As explained in our article “Did Albert Einstein Fail Math?”, Einstein was remarkably capable at mathematics from an early age. Talmey did not rescue a failing student. He encouraged an already gifted one.

That distinction matters because discovering talent is important, but recognizing it, taking it seriously, and providing the resources needed to develop it can be just as consequential.

9. Dr. Joseph Bell: The Scottish Surgeon Who Became Sherlock Holmes

When Arthur Conan Doyle enrolled at the University of Edinburgh to study medicine in 1876, he probably did not imagine that one of his professors would eventually become the inspiration for the most famous fictional detective in literary history.

Then again, Dr. Joseph Bell was not an ordinary professor.

Bell was a Scottish surgeon whose diagnostic abilities seemed almost supernatural to students who watched him work. He could examine a patient, observe seemingly insignificant details of clothing, behavior, accent, and physical appearance, and then make remarkably accurate deductions about the person’s occupation, background, or recent activities.

His secret was not clairvoyance, which was probably disappointing to anyone hoping for a medical diagnosis without the inconvenience of an examination. Bell relied on careful observation, reasoning, and an extraordinary attention to detail.

Conan Doyle studied under Bell and later worked as his clerk at the Royal Infirmary of Edinburgh. The young medical student was fascinated by his professor’s ability to draw conclusions from evidence that others overlooked.

Years later, Doyle transformed those methods into the investigative techniques of Sherlock Holmes.

Holmes first appeared in the 1887 novel A Study in Scarlet, demonstrating an uncanny ability to reconstruct events and identify important clues from details that bewildered everyone else.

Bell’s influence was not merely a resemblance invented by later literary historians. Doyle himself acknowledged the connection between his former professor and the fictional detective.

Holmes became one of literature’s most enduring characters, appearing in stories, films, television programs, stage productions, and more adaptations than even the most dedicated Baker Street enthusiast could reasonably be expected to watch.

Bell continued his medical career, but his lasting cultural influence came from the student who transformed his diagnostic techniques into detective fiction.

As we have previously examined in our collection of Sherlock Holmes facts, the great detective acquired a remarkable collection of habits, quotations, and characteristics that were not always present in Doyle’s original stories.

But the essential skill that made Holmes famous—the ability to notice what everyone else missed—owed a considerable debt to a real physician teaching medical students in Edinburgh.

Which suggests that one of the most enduring contributions to detective fiction was made by a doctor who wasn’t trying to solve murders at all.

10. Christian Gottlob Neefe: The Music Teacher Who Recognized Beethoven’s Genius

It is difficult to imagine a world without Ludwig van Beethoven. His symphonies, sonatas, and other compositions remain central to classical music more than two centuries after they were written.

Even people who know virtually nothing about classical music generally recognize the opening notes of his Fifth Symphony. The tune became such a powerful symbol that, during World War II, the BBC used its rhythm as a musical representation of the Morse code signal for V, meaning victory.

Yet before Beethoven became Beethoven, he was a talented young musician in Bonn who needed instruction, encouragement, and opportunities to develop his abilities.

One of the most important people to provide those things was Christian Gottlob Neefe.

Neefe was a German composer, organist, and musical director who became one of Beethoven’s early teachers in Bonn. He helped introduce the young musician to important musical works, including compositions by Johann Sebastian Bach, and encouraged his developing abilities. Precisely how extensive Neefe’s instruction was remains a subject of historical debate, but his recognition of Beethoven’s unusual promise is well documented.

In March 1783, Neefe publicly praised his young pupil in the musical journal Magazin der Musik. He described Beethoven’s remarkable abilities at the keyboard, his familiarity with Bach’s compositions, and his promising progress in musical composition. Neefe went so far as to predict that, with continued development, the twelve-year-old musician might become a second Wolfgang Amadeus Mozart.

This was not casual praise. Mozart was already one of Europe’s most celebrated musicians, and comparing a twelve-year-old student to him was the eighteenth-century equivalent of predicting that a youngster taking batting practice might become the next Babe Ruth. It was a remarkable endorsement, particularly from someone whose professional reputation depended on knowing the difference between genuine musical talent and an enthusiastic parent insisting that his child was a prodigy.

Neefe also helped Beethoven gain practical musical experience and arranged for the publication of some of his early compositions. The full extent of his influence remains uncertain, and historians have questioned the traditional portrayal of an especially close relationship between teacher and pupil. Nevertheless, Neefe’s willingness to recognize and publicly promote Beethoven’s abilities is beyond serious dispute. Whatever the precise limits of his instruction, he helped bring attention to a young musician whose greatest achievements still lay far in the future.

Beethoven’s appreciation for Neefe also appears in the historical record. A report published in 1793 preserved words attributed to Beethoven thanking his former teacher for his advice and acknowledging that Neefe deserved a share of the credit if he ever became a great man. Although the original correspondence has not survived, the published remark provides an intriguing glimpse of how Beethoven’s early relationship with Neefe was understood at the time.

Neefe died in 1798, before Beethoven composed many of the works that would establish his enduring reputation. He never witnessed the full extent of his pupil’s success. Nevertheless, he had recognized the possibilities in a gifted young musician and helped provide the tools necessary to develop them.

History remembers Beethoven as a genius. Neefe deserves at least a little credit for recognizing one before the rest of the world caught up.

The Unsung People Who Changed History—and the Ones Who Still Might

There is an understandable temptation to interpret all these stories as proof that history turns on single encounters. If Mordecai Ham had not preached in Charlotte, would Billy Graham have become an evangelist? If John Stevens Henslow had not recommended Darwin for the Beagle expedition, would someone else have developed the theory of evolution? Would Sherlock Holmes exist if Arthur Conan Doyle had studied under a less observant physician?

These are fascinating questions, although historians are notoriously reluctant to answer them definitively. The past is complicated enough without conducting imaginary experiments on events that cannot be repeated. Famous people rarely owe their accomplishments to a single influence, but that doesn’t diminish the importance of those who helped them along the way.

And perhaps that’s where these stories become a little more personal.

Think about the people who have influenced your own life. Was there a teacher who saw something in you that you hadn’t yet recognized in yourself? A mentor who invested time and attention when there was no particular reason to expect anything in return? A friend who offered an encouraging word at precisely the moment you needed one? Perhaps someone challenged you with an uncomfortable conversation that you didn’t especially appreciate at the time but later realized you desperately needed.

Chances are, you can identify at least one person whose influence helped make you who you are today. They may never have appeared in a newspaper, written a bestselling book, or received a prestigious award. Their names may mean absolutely nothing to the rest of the world. But to you, their contributions were anything but insignificant.

Have you ever told them?

History has never been especially diligent about sending thank-you notes, but there’s no reason we have to follow its example. If those individuals are still around, perhaps it’s worth letting them know that their investment made a difference. They might be surprised to discover just how consequential an ordinary conversation or small act of encouragement turned out to be.

But there’s another question worth considering, and this one looks forward rather than backward.

Whose life might you be influencing right now?

Somewhere in your circle of acquaintances may be a future scientist, educator, inventor, artist, pastor, or leader whose greatest accomplishments are still decades away. Perhaps it’s a young person who needs someone to take an interest in an unusual talent. Perhaps it’s a struggling colleague who could benefit from an encouraging word, a difficult but necessary conversation, or someone willing to invest a little time in helping them develop their abilities.

You probably won’t recognize the historical significance of the moment. Edward Kimball certainly didn’t walk into that Boston shoe store expecting to launch one of the nineteenth century’s greatest evangelistic careers. John Stevens Henslow wasn’t trying to revolutionize biology when he recommended a promising student for a voyage aboard the Beagle. They were simply doing what they believed was worthwhile for someone who mattered to them.

And that may be the most remarkable thing about these unsung people who changed history. Their influence didn’t require extraordinary wealth, political power, or public recognition. It required paying attention to another person and being willing to make an investment whose ultimate value they might never see.

We tend to assume that the people who change history are the ones whose names eventually appear in the history books. But the people who make history and the people who make history possible are not always the same people.

So think about those who helped shape your life. Thank them if you can. And then consider the people whose lives intersect with yours today. One of them might someday accomplish something extraordinary, in part because you took the time to encourage, challenge, or invest in them.

You may never know what difference you made.

Then again, neither did Mordecai Ham when he preached that sermon.
