Horatio Alger, Jr., an American author, born at Revere, near Boston, Mass., Jan. 13, 1834. He graduated at Harvard college in 1852, and was afterward engaged partly in teaching and partly in writing, being for a time editorially connected with two Boston newspapers. He then spent a year in travel in Europe, corresponding with American papers. Upon his return he resumed teaching and writing. In 1866 he took up his residence in New York, where he became deeply interested in the condition of the street boys. This has given form to most of his later writings. Prominent among these are the "Rag-gen Dick" series and the " Tattered Tom" series. With the exception of "Helen Ford, a Novel," and various magazine papers, Mr. Alger's writings belong mainly to the class of books for the young.
