Robert Sherwood Haggart (March 13, 1914 in New York City – December 2, 1998 in Venice, Florida) was a dixieland jazz double bass player, composer and arranger. Although he is associated with dixieland he was in fact one of the finest rhythm bassists of the Swing Era. 　　One of the last survivors of Bob Crosby's Bobcats, Bob Haggart was a top bassist for 60 years. Originally a guitarist, Haggart taught himself bass while in high school. He gained fame when he joined Bob Crosby in 1935, not only supplying his supportive and swinging bass but contributing arrangements and writing such songs as "What's New," "South Rampart Street Parade," "My Inspiration," and "Big Noise From Winnetka," the latter a colorful duet with drummer Ray Bauduc. After Crosby broke up his band in 1942, Haggart became a studio musician and was on a countless number of sessions (particularly for Decca). In addition to his studio work, the busy bassist teamed up with Yank Lawson for recordings as the Lawson-Haggart Band. Bob Haggart participated in many Bobcat reunions with Bob Crosby, co-led the World's Greatest Jazz Band with Lawson starting in 1968, and was a steady fixture at many jazz parties and festivals through the years prior to his death on December 2, 1998. 　 　　In 1935, Haggart became a member of the Bob Crosby Band. He arranged and composed "Big Noise from Winnetka", "My Inspiration", "What's New?", and "South Rampart Street Parade". He remained with the band until it dissolved in 1942, then began working as session musician, with much of his time spent at Decca Records. He recorded with Billie Holiday, Duke Ellington, Benny Goodman, and Ella Fitzgerald; his arrangements can be heard on Fitzgerald's album Lullabies of Birdland. 　　He and Yank Lawson formed the Lawson-Haggart Band, and they also led the World's Greatest Jazz Band from 1968–1978. He appeared at jazz festivals until his death on December 2, 1998 in Venice, Florida.
