Wisner was born in Philadelphia; he received classical training as a youngster and attended Temple University as a psychology student in the late 1950s.
He formed the Jimmy Wisner Trio in 1959 with Chick Kinney on drums and Ace Tesone on bass. This ensemble backed musicians who toured through Philadelphia, including Mel Torme, Carmen McRae, Dakota Staton, and the Hi-Lo's.
In 1959, he released his debut jazz album, Blues For Harvey, and followed the next year with Apperception, but in 1960 recorded a rock & roll adaptation of Edvard Grieg's Piano Concerto in A Minor, using shellac on the hammers of a cheap piano so as to effect a honky tonk sound. So as not to alienate his jazz fans, he released the tune, titled "Asia Minor", under the name Kokomo; he was turned down by 10 labels and had to release the track on his own label Future Records. The song became a hit, reaching #8 on the Billboard Hot 100, and #35 on the UK Singles Chart despite having been banned by the BBC. Wisner released further singles as Kokomo on his prior label, Felsted, but did not have another hit.
Following the success of "Asia Minor", Wisner launched a successful career as a songwriter, producer, and composer for film and television. With Billy Jackson, a frequent songwriting collaborator, he wrote "Don't Throw Your Love Away", a #1 UK hit for the Searchers in 1964, as well as the Tymes'"Somewhere", written with Norma Mendoza, which went Top 20 in the UK. Wisner has had over 250 of his compositions recorded.
As a producer and arranger Wisner worked with Bobby Rydell ("The Joker", by Newley-Bricusse from Roar of the Greasepaint) as well as numerous others including Freddy Cannon, Neil Sedaka, Bobby Vinton, Herbie Mann, Len Barry ("1 - 2 - 3"), Miriam Makeba, Judy Collins, Paul Evans, Spanky and Our Gang, Tony Bennett, the Cowsills, Carly Simon, Al Kooper, Iggy Pop, Barbra Streisand, Tommy James, Brigitte Bardot, and Roberto Carlos as well as Randy & the Rainbows.
He also headed Columbia Records' A&R department from 1968 to 1969, where he recorded Donna Marie, who went on to perform with the Archies. He produced, arranged, written and/or conducted more than 100 hit records—earning 36 Gold and 22 Platinum awards. Wisner died on March 13, 2018, at age 86.
