Nicknamed "Silk Hat Harry," this mugging scene-stealer was one of Sennett's mainstays off-and-on from 1915 to 1932, initially as shifty white-collar villains with slippery fingers or backslapping "best friends."
Joining Keystone for the first time at the start of January 1915 with wife May Emory, Gribbon worked intermittently at the Sennett studio through 1919(serving in WW1 during that time), then returned again to star in some of Sennett's early Pathe releases of 1923-24. Gribbon later rejoined Sennett to star in his Educational talkies, appearing in more than two dozen shorts during 1928-32. Born in New York City, the 6'0'', blue-eyed, brown-haired Gribbon had been a newsboy who pursued a career as a baritone at age 16, and worked with the vaudeville team of Heelan and Helf. He appeared in "Flo Flo" with Stella Mayhew(1904), worked in the 1913 Ziegfeld Follies, played the lead in "Buster Brown" and also worked for the Shuberts and George M. Cohan. Gribbon had been the leading comic of the Gayety Company at the Morosco Theater before his Sennett servitude, and carried many broad stage traits with him, as well as restless heart.
Just over three months after joining Sennett, Gribbon and wife May left Keystone to join Lehrman's L-KO Comedies. The Gribbons rejoined Keystone-Triangle in August 1915 and stayed to make post-Sennett Keystones for Triangle in 1917-18. Harry rejoined Sennett in 1918, left for L-KO, but returned to Sennett in 1919. He then left again for Fox Sunshine in 1919, followed by the feature "Up in Mary's Attic", shorts for Al Christie, Universal's Star and Century Comedies and Norman Manning/Arrow(1921).
After that Gribbon returned to vaudeville on the Keith and Pantages circuits in a song and comedy duo with his wife. He came back to films to work at Mermaid(1923), then Sennett again, followed by another vaudeville stint, and then features. In 1928 for MGM, he had a recurring gag role as a mystified cop in Keaton's The Cameraman, a memorable part as a hyperactive comedy director in Show People and also appeared in Honeymoon.
From 1929 to 1933 Gribbon worked frequently in Warner Bros releases. In 1930-31 Gribbon also made shorts for RKO-Pathe. Relocating to New York, Gribbon made shorts for Vitaphone in 1934 and Educational in 1936-38. He acted in Broadway in plays. In 1943, Gribbon replaced John Alexander in the role of Teddy Brewster in "Arsenic and Old Lace" at the Hudson Theater. By that time Gribbon had developed a serious drinking problem that plagued him the rest of his life. His wife May died in 1948, and in later years Harry was reduced to seeking jobs like emceeing talent shows around the New York area.
When Gribbon fell ill, he relocated from New York to the Motion Picture Home and County Hospital in Woodland Hills, California, where he died at 76. He's interred at Holy Cross Cemetery, Culver City.
