Fred Katz (born February 25, 1919) is an American composer, songwriter, conductor, cellist, pianist, and professor. In jazz, a principal contribution of Katz has been, as Leonard Feather noted, “to put the cello to full use both in arco and pizzicato solos.” Oscar Pettiford had already indicated the considerable jazz potential of plucked (pizzicato) cello, but with Oscar, the instrument remained secondary to his primary instrument, the bass. Katz was the first musician to utilize all of the cello in jazz as his chief instrument in that idiom.
