John Hartman was an American drummer who was a co-founder and original drummer of the Doobie Brothers. At the band's inception, Hartman was the sole drummer. However, in late 1971, the group added drummer Michael Hossack, and the dual-drummer formation remained until 2016 when Ed Toth became the band's sole drummer. Hossack was replaced in 1973 by Keith Knudsen.
