Robert Leo Hackett (January 31, 1915 – June 7, 1976) was an American jazz musician who played trumpet, cornet, and guitar with the bands of Glenn Miller and Benny Goodman in the late 1930s and early 1940s. Hackett was a featured soloist on some of the Jackie Gleason mood music albums during the 1950s.
Hackett was born in Providence, Rhode Island. He made his name as a follower of cornet player Bix Beiderbecke. Benny Goodman hired the talented twenty-three year old to recreate Bix's "I'm Coming Virginia" solo at his (Goodman's) 1938 Carnegie Hall concert. In the late 1930s Hackett played lead trumpet in the Vic Schoen Orchestra which backed the Andrews Sisters. Hackett can be heard on the soundtrack to the 1940 Fred Astaire movie Second Chorus.
In 1939, the talent agency MCA asked Hackett to form a big band with its backing. When the band failed, he was in substantial debt to MCA after it folded. He joined the bands of Horace Heidt and then Glenn Miller to pay this debt. To make matters worse, his lip was in bad shape after dental surgery, making it difficult for him to play the trumpet or cornet. Glenn Miller offered him a job as a guitarist. "When I joined the band and I was making good money at last, [...] [jazz critics] accused me of selling out. Hell I wasn't selling out, I was selling in! It's funny, isn't it, how you go right into the wastebasket with some critics the minute you become successful."
Despite lip problems, Hackett could play occasional, short solos, and he can be heard playing with the Glenn Miller Orchestra on "A String of Pearls". A dream come true for Hackett was his inclusion in Louis Armstrong's 1947 Town Hall Jazz Concert. In 1954, he appeared as a regular on the ABC variety show The Martha Wright Show, also known as The Packard Showroom.
Bobby Hackett married Edna Lillian Lee Hackett (d.2000) in 1937. The Hacketts lived primarily in New York City and spent summers in Cape Cod, Massachusetts. They had a daughter, Barbara (d. 2003); and a son, Ernie, who became a professional drummer.
