Herb Williams’ (Herbert Schussler Billerbeck, 1884-1936) whole act revolved around a trick piano that fell apart like Harry Langdon’s automobile, but also was the source of many other surreal gags. Ironically, he was a legitimate, trained pianist (he studied at the Philadelphia Conservatory of Music). His partners over the years included his first wife Hilda Woofus, his second wife Jean Halpin, and Tom Kennedy (a different one, I think, from the Keystone comedian). By the mid 20s Williams was a big time headliner, who played the Palace several times. Broadway appearances included Earl Carroll’s Vanities of 1930 and The Farmer Takes a Wife (1934). He was just beginning to break into films when he passed away in 1936.
