His father was a famous hunter and rifle shot, and it was doubtless his exploits and those of his associates, with their tales of adventure which gave the son his taste for the breezy backwoods and for depicting the stirring life of the early settlers on the frontier. Mr. Ellis began writing at an early age and his work was acceptable from the first. His parents removed to New Jersey while he was a boy and he was graduated from the State Normal School and became a member of the faculty while still in his teens. He was afterward principal of the Trenton High School, a trustee and then superintendent of schools. By that time his services as a writer had become so pronounced that he gave his entire attention to literature. He was an exceptionally successful teacher and wrote a number of text-books for schools, all of which met with high favor. For these and his historical productions, Princeton College conferred upon him the degree of Master of Arts.
