Joseph Henry Roberts was a comic actor, who appeared in 16 of Buster Keaton's 19 silent short films of the 1920s.
"Big Joe" Roberts, as he was known in vaudeville, toured the country with his first wife, Lillian Stuart Roberts, as part of a rowdy act known as Roberts, Hays, and Roberts. Their signature routine was called "The Cowboy, the Swell and the Lady."
At this time, in the first decade of the twentieth century, Buster Keaton's father, Joe Keaton, had started a summer Actors' Colony for vaudevillians between Lake Michigan and Muskegon Lake in Michigan. Roberts became acquainted with the Keaton family as a member of this community.
Sources show that Roberts made only two films without Keaton.
