Career
Lou Costello called him their "chief idea man". Grant was a burlesque comedian, straight man and producer. He worked for the Mutual Burlesque wheel and the Minsky"s in the 1930s.
In 1938, after Abbott and Costello joined the Kate Smith radio program, they hired Grant, who was then working in Toronto, to be their head writer
The team performed their signature sketch, Who"s on First?, on the program in March, 1938. Grant contributed to the sketch and every other Abbott and Costello routine on radio and, later, films.
He also wrote for the Colgate Comedy Hour as well as authoring many screenplays. Grant"s gags were also performed by the teams Dean Martin and Jerry Lewis and Ma and Pa Kettle.
Grant usually contributed to the Abbott and Costello films after other writers had done a first or second draft.
He would go through the script and see where he could inject comedy routines. He usually worked alone and most of his material would be included in the final film because he was the only writer Abbott and Costello listened to He was often on the set during filming.
During the Red Hysteria of the early 1950s, Lou Costello became convinced there was a communist conspiracy to infiltrate the film industry and demanded that his employees sign a petition swearing that had no part in any Communist work or organization.
Grant would not sign and Costello fired him, meaning Grant did not work on Lost in Alaska. Grant was not blacklisted and went on to work for Martin and Lewis on Sailor Beware.
Costello felt that the script to Lost in Alaska suffered because of Grant"s absence and rehired him for Abbott and Costello Meet Captain Kidd. Along with his Abbott and Costello films, he wrote Ma and Pa Kettle at the Fair (1951), Martin and Lewis"s Sailor Beware (1952), Spike Jones"s and Buddy Hackett"s version of Fireman Save My Child (1954), and the detective drama Ring of Fear (1954) featuring Pat O"Brien and Mickey Spillane.
