Lonnie Smith (born July 3, 1942), styled Dr. Lonnie Smith, is an American jazz Hammond B3 organist who was a member of the George Benson quartet in the 1960s. He recorded albums with saxophonist Lou Donaldson for Blue Note before being signed as a solo act. He owns the label Pilgrimage.

He was born in Lackawanna, New York, into a family with a vocal group and radio program. Smith says that his mother was a major influence on him musically, as she introduced him to gospel, classical, and jazz music. He was part of several vocal ensembles in the 1950s, including the Teen Kings which included Grover Washington Jr., on sax and his brother Daryl on drums. Art Kubera, the owner of a local music store, gave Smith his first organ, a Hammond B3. George Benson Quartet 

Smith’s affinity for R&B melded with his own personal style as he became active in the local music scene. He moved to New York City, where he met George Benson, the guitarist for Jack McDuff‘s band. Benson and Smith connected on a personal level, and the two formed the George Benson Quartet, featuring Lonnie Smith, in 1966.

After two albums under Benson’s leadership, It’s Uptown and Cookbook, Smith recorded his first solo album (Finger Lickin’ Good Soul Organ) in 1967, with George Benson and Melvin Sparks on guitar, Ronnie Cuber on baritone sax, and Marion Booker on drums. This combination remained stable for the next five years.

After recording several albums with Benson, Smith became a solo recording artist and has since recorded over 30 albums under his own name. Numerous prominent jazz artists have joined Smith on his albums and in his live performances, including Lee Morgan, David “Fathead” Newman, King Curtis, Terry Bradds, Blue Mitchell, Joey DeFrancesco and Joe Lovano.
