Born in 1943, at Darfield, near Barnsley, Martyn's first job at the age of fifteen was as a blacksmith but in his late teens joined Sheffield City Police, working on the streets of Attercliffe and Darnall until 1969. A few interesting years in CID followed but he returned to grassroot policing, serving for another seven years. A long-time resident of Wentworth, Martyn was consulted by author Catherine Bailey when she was compiling her best-selling book Black Diamonds. More recently, with his wife Christine, Martyn published Wentworth in Old Photographs.
