Alexander Hamilton was but twelve years old when he wrote from his home in St. Croix, in the West Indies, to a friend in America: "I contemn the grovelling condition of a clerk, or the like, to which my fortune condemns me, and would willingly risk my life, though not my character, to exalt my station. I am confident, Ned, that my youth excludes me from any hope of immediate preferment, nor do I desire it, but I mean to prepare the way for futurity." Not for a day did he lose sight of his purpose. The opportunity he sought came years later. He sailed for America, and began the career that led to usefulness and fame. As a boy Robert Fulton was ambitious. He had two dreams. He wished to go to Europe to study art, and he wished to buy a farm for his widowed mother. For these objects he saved every dollar he could. On his twenty-first birthday he took his mother and sister to the home he had bought for them, and later in the same year he sailed for Europe. When Peter Cooper was making his way against odds in New York City he felt the need of an education. But he had to work by day and there was no night school. Night after night he studied by the light of a tallow candle. And while he studied, his life purpose was formed: some day he would make it easy for apprentice boys to secure an education after working hours. Many years passed before he was able to carry this purpose into effect. By this time the apprentice system had been displaced, but he felt that young people still needed the school he had in mind. In 1859, nearly fifty years after his own boyhood struggle, he founded Cooper Union, in which thousands have had the opportunity "to open the volume of Nature by the light of truth--so unveiling the laws and methods of Deity that the young may see the beauties of creation, enjoy its blessings and learn to love the Being from whom cometh every good and perfect gift." As a boy Abraham Lincoln made up his mind "to live like Washington." He was twenty-two years old when, in New Orleans,--where he had taken a flatboat loaded with produce--he saw a slave auction and spoke the never-to-be-forgotten words: "If ever I get a chance to hit that thing, I'll hit it hard." Thirty-five years later came his chance, and he did "hit that thing hard" with the Emancipation Proclamation. Alexander Graham Bell's life ambition was to teach deaf children how to articulate. Funds were short. That he might have more funds he engaged in experiments that led to the invention of the telephone. When the telephone instrument was given the attention it deserved at the Philadelphia Centennial of 1876, the inventor wrote triumphantly to his parents: "Now I shall have the money to promote the teaching of speech to deaf children."
