Mark Twain lost more than a half million dollars in his lifetime from the failed inventions in which he invested. The invention that cost Twain the most was one in which he did not invest in: Alexander Graham Bell’s telephone. When Bell personally offered Twain a chance to invest in his telephone, Twain responding by telling him that he wasn’t interested because he had been burnt once too often on inventions.
