Richmond's father was a German immigrant from Hanover who worked as a printer in Reedsburg. His mother was Wisconsin-born and raised, and of German immigrant parents. Growing up in rural Wisconsin, he became an expert horseman, and this skill would later earn him roles in western movies.

Richmond, who was not a contracted actor, made films with nearly all major film studios and by the late 1910s and early 1920s played both leading and second lead roles in crime dramas, romantic dramas, serials and Westerns. His career as an actor spanned over four decades and he appeared in prominent roles in Westerns, often playing a villain, particularly later in his career during the sound era.^[3]
