Frederick Bailey Deeming

Frederick Bailey Deeming (30 July 1853 – 23 May 1892) was an English-born Australian gasfitter and murderer.

Deeming was born in Ashby-de-la-Zouch, Leicestershire, England, son of Thomas Deeming, brazier, and his wife Ann, née Bailey. He was a "difficult child" according to writers Maurice Gurvich and Christopher Wray. At 16 years of age he ran away to sea, and thereafter, he began a long career of crime, largely thieving and obtaining money under false pretences. He was also responsible for the murder of his first wife Marie, and his four children, at Rainhill, England, on or about 26 July 1891, and a second wife, Emily, at Windsor, Melbourne, on 24 December 1891.

Less than three months elapsed between the discovery of Emily Mather’s body in Windsor, Melbourne, in March 1892, and Deeming’s execution for her murder in May 1892; a remarkably short time by comparison to modern western legal standards. Not only was this due to unusually efficient police work, it was also a result of the considerable international media interest the murder attracted. For example, it was an English journalist working for the Melbourne Argus who first approached Emily Mather’s mother in Rainhill, delivering the news of her daughter’s murder. Another factor was Deeming’s behaviour in public; for while often using different names, he usually drew attention to himself with behaviour variously described as aggressive, ostentatious, ingratiating and overly attentive to women.
