(born as Emanuel Klein on February 4, 1908; died May 31, 1994) was a jazz trumpeter most associated with swing.
He began with Paul Whiteman in 1928 and was active throughout the 1930s playing with several major bands of the era including the Dorseys and Benny Goodman. In 1937 he moved to California and worked with Frank Trumbauer's orchestra. And in early 1940, credited as Mannie Klein, he appears on Artie Shaw And His Orchestra recordings. He also did soundtracks and played trumpet for the film From Here to Eternity, but was uncredited. He also worked with musicians associated with "West Coast jazz" in the 1950s. During the early 60s he appeared on several Dean Martin recordings. He played piccolo trumpet on Hugo Montenegro's hit version of the main theme to the 1966 film, The Good, the Bad and the Ugly.
Klein was regarded as one of the most proficient trumpet players of his, or any generation. In addition to being a brilliant technician, Klein possessed an uncanny ability to mimic the styles of many other prominent trumpeters, namely Bunny Berigan and Ziggy Elman.
Klein died at the age of 85 in Los Angeles on May 31, 1994.
