Malcolm B. Wiseman (born May 23 1925 in Crimora, Virginia) is a bluegrass singer.
The bearded singer is one of the cult figures of Bluegrass music.
He studied at the Shenandoah Conservatory of Music in Dayton, Virginia but besides his first attempts as musician he had to work as discjockey at the radio station WSVA in Harrisonburg, Virginia.
His career began as guitarist in the band of country singer Molly O'Day but when Flatt & Scruggs separated with Bill Monroe, Wiseman became the guitarist of the Foggy Mountain Boys, the band of Lester Flatt & Earl Scruggs. Later he has changed to the band of Bill Monroe.
After a performance at the Louisiana Hayride he became popular as solo artist.
During the Folk revival in the 1960s he had successful gigs at the Hollywood Bowl and the Carnegie Hall. In 1993 Wiseman was inducted into the International Bluegrass Music Hall of Honor.
