ddie Lang (born Salvatore Massaro, October 25, 1902 – March 26, 1933) 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.

The son of an Italian-American instrument maker, Lang was born in Philadelphia, Pennsylvania, and grew up with violinist Joe Venuti. His first instrument was violin when he was seven. He performed on violin in 1917 and became a member of a trio. In 1920, he dropped the violin for banjo and worked with Charlie Kerr, then Bert Estlow, Vic D’Ippolito, and Billy Lustig‘s Scranton Siren Orchestra. A few years later, he dropped the banjo for guitar when he became a member of the Mound City Blue Blowers led by Red McKenzie. He recorded one of the first solos in 1924 on “Deep 2nd Street Blues”. His performances with McKenzie’s band drew attention, and he found many jobs as a freelance guitarist. Before Lang, the guitar hadn’t been a prominent instrument in jazz bands and dance orchestras. Lang suffered from occasional laryngitis, chronic sore throat, and digestion problems. After a doctor recommended a tonsillectomy, Crosby urged Lang to have the operation. Assured that the operation was routine, Lang entered Park West Hospital in Manhattan, but he never awoke from the surgery. He died at the age of thirty in 1933. The cause of his death is uncertain.
