Although the DEI (Dave Elman Induction) was first used in teaching medical hypnosis in 1949, it originated in 1912. Dave Elman, then age 12, began using it on his classmates after experimenting with other methods for a few years. The DEI became the foundation of Elman’s advanced methods taught to over 10,000 physicians and dentists.
Wilson was born in Austin, Texas, on November 24, 1912. He studied piano and violin at Tuskegee Institute in Tuskegee, Alabama. After working in the Lawrence "Speed" Webb band, with Louis Armstrong, and also understudying Earl Hines in Hines's Grand Terrace Cafe Orchestra, Wilson joined Benny Carter's Chocolate Dandies in 1933. In 1935, he joined the Benny Goodman Trio (which consisted of Goodman, Wilson and drummer Gene Krupa, later expanded to the Benny Goodman Quartet with the addition of Lionel Hampton).
Besides occasional appearances with Benny Goodman, pianist Teddy Wilson taught summer courses at the famous Juilliard School for music from 1946 to 1952. Despite this prestigious profession, he recorded only irregularly during these years and made most of his money as a staff pianist for WNEW. In the fall of 1952, he went on a brief tour to Scandinavia where he was finally able to record again.
