New York-born Boss was one of the screen's first child stars.
He was already a stage veteran when he made his screen debut in Thanhouser's The Actor's Children (1910).
He appeared on Broadway opposite Adeline Genée in The Silver Star.
Later he became one of Edison Studios's most popular players, but the studio constantly had to battle rumors questioning his true age.
Boss's popularity waned in the late 1910s and he later worked as a prop man.
A young woman hits Hollywood, determined to become a star.
Made by the Edison Manufacturing Company and directed by Edwin S. Porter, the film starred Gladys Hulette as Alice. Being a silent film, naturally all of Lewis Carroll's nonsensical prose could not be used, and, being only a one-reel picture, most of Carroll's memorable characters in his original 1865 novel similarly could not be included. What was used in the film was faithful in spirit to Carroll, and in design to the original John Tenniel illustrations. Variety complimented the picture by comparing it favorably to the "foreign" film fantasies then flooding American cinemas.
