Dennis Day (born Owen Patrick Eugene McNulty; May 21, 1916 – June 22, 1988)[1][2][3] was an American actor, comedian and singer.

[4][5] Day graduated from the Cathedral Preparatory School and Seminary and attended Manhattan College in the Bronx,[6] where he sang in the glee club.

[citation needed] Day appeared for the first time on Jack Benny's radio show on October 8, 1939, taking the place of another tenor, Kenny Baker.

[6] He was introduced (with actress Verna Felton playing his overbearing mother) as a young (19-year-old), naive boy singer – a character he kept through his whole career.

On both the Benny program and his own show, Day performed impressions of various celebrities of the era, including Ronald Colman, Jimmy Durante, and James Stewart, as well as many dialects.

His last radio series was a comedy and variety show that aired on NBC's Sunday afternoon schedule during the 1954–55 season.

[citation needed] When Day got his own radio sitcom, he continued to play essentially the same character that he originated on Benny's program.

He continued to appear as a regular cast member when The Jack Benny Program became a TV series, staying with the show until it ended in 1965.

On this show, Day played a less-fictionalized version of himself, using his natural voice and behaving as an adult who was considerably more mature than his Benny character.

He starred as railroad employee Jason Barnes in the 1962 Death Valley Days TV episode "Way Station".

For the soundtrack of My Wild Irish Rose (1947), a biopic about Chauncey Olcott, Day provided the singing voice to the acting of Dennis Morgan.
