Leopold Horace Ognall (20 June 1908 – 12 April 1979),^[1] known by the pen names Hartley Howard and Harry Carmichael, was a British crime novelist. Ognall was born in Montreal and worked as a journalist before starting his fiction career. He wrote over 90 novels before his death in 1979. The private eye Glenn Bowman was one of his most successful characters. As Harry Carmichael, Ognall's primary series characters were John Piper (an insurance assessor) and Quinn, a crime reporter.

Ognall's son Sir Harry Ognall became a high court judge and conducted the hearings regarding former Chilean leader Augusto Pinochet.
