Eddie Lang was an American musician who is credited as the father of jazz guitar. During the 1920s, he gave the guitar a prominence it previously lacked as a solo instrument, as part of a band or orchestra, and as accompaniment for vocalists. He recorded duets with guitarists Lonnie Johnson and Carl Kress and jazz violinist Joe Venuti, and played rhythm guitar in the Paul Whiteman Orchestra and was the favoured accompanist of Bing Crosby.

Roger Wolfe Kahn was an American jazz and popular musician, composer, bandleader and an aviator.
