Horatio Alger, Jr., an author who lived among and for boys and himself remained a boy in heart and association till death, was born at Revere, Massachusetts, January 13, 1834. He was the son of a clergyman, was graduated at Harvard College in 1852, and at its Divinity School in 1860 and was pastor of the Unitarian Church at Brewster, Mass., in 1862-66. In the latter year he settled in New York and began drawing public attention to the condition and needs of street boys. He mingled with them, gained their confidence showed a personal concern in their affairs, and stimulated them to honest and useful living. With his first story he won the hearts of all red-blooded boys everywhere, and of the seventy or more that followed over a million copies were sold during the author's lifetime. In his later life he was in appearance a short, stout, bald-headed man, with cordial manners and whimsical views of things that amused all who met him. He died at Natick, Mass., July 18, 1899. Mr. Alger's stories are as popular now as when first published, because they treat of real live boys who were always up and about-just like the boys found everywhere to-day. They are pure in tone and inspiring in influence, and many reforms in the juvenile life of New York may be traced to them.
