James Oscar Smith (December 8, 1925 – February 8, 2005) or 1928 was an American jazz musician whose albums often charted on Billboard magazine. He helped popularize the Hammond B-3 organ, creating a link between jazz and 1960s soul music.

In 2005, Smith was awarded the NEA Jazz Masters Award from the National Endowment for the Arts, the highest honor that America bestows upon jazz musicians.

There is confusion about Smith’s birth year, with various sources citing either 1925 or 1928. Born James Oscar Smith in Norristown, Pennsylvania, at the age of six he joined his father doing a song-and-dance routine in clubs. He began teaching himself to play the piano. When he was nine, Smith won a Philadelphia radio talent contest as a boogie-woogie pianist. After a stint in the U.S. Navy, he began furthering his musical education in 1948, with a year at Royal Hamilton College of Music, then the Leo Ornstein School of Music in Philadelphia in 1949. He began exploring the Hammond organ in 1951. From 1951 to 1954 he played piano, then organ in Philly R&B bands like Don Gardner and the Sonotones. He switched to organ permanently in 1954 after hearing Wild Bill Davis.

He purchased his first Hammond organ, rented a warehouse to practice in and emerged after little more than a year. Upon hearing him playing in a Philadelphia club, Blue Note’s Alfred Lion immediately signed him to the label and his second album, The Champ, quickly established Smith as a new star on the jazz scene. He was a prolific recording artist and, as a leader, dubbed The Incredible Jimmy Smith, he recorded around forty sessions for Blue Note in just eight years beginning in 1956. Albums from this period include The Sermon!, House Party, Home Cookin’, Midnight Special, Back at the Chicken Shack and Prayer Meetin’.

Smith signed to the Verve label in 1962. His first album, Bashin’, sold well and for the first time set Smith with a big band, led by Oliver Nelson. Further big band collaborations followed, most successfully with Lalo Schifrin for The Cat and guitarist Wes Montgomery, with whom he recorded two albums: The Dynamic Duo and Further Adventures Of Jimmy and Wes. Other albums from this period include Blue Bash and Organ Grinder Swing with Kenny Burrell, The Boss with George Benson, Who’s Afraid of Virginia Woolf?, Got My Mojo Working, and Root Down.

During the 1950s and 1960s, Smith recorded with some of the great jazz musicians of the day such as Kenny Burrell, George Benson, Grant Green, Stanley Turrentine, Lee Morgan, Lou Donaldson, Tina Brooks, Jackie McLean, Grady Tate and Donald Bailey.

The Jimmy Smith Trio performed “When Johnny Comes Marching Home” and “The Sermon” in the 1964 film Get Yourself a College Girl.
