Born in 1905, Leslie Overend was encouraged by his father at an early age to take up photography, and when he was thirteen produced his first published photograph. Taken from the top of Bradford Town Hall it showed the Armistice celebrations on 11 November 1918, and was used by the 'Bradford Daily Argus'. This early success prompted Overend to make a career in photography and journalism, and with his father he founded the Overend Press Agency in 1926. In a long journalistic career he covered events throughout Yorkshire. He died in 1989.

The NRM acquired Overend's collection of railway photographs in 1984. It features locomotives built for the LMS and LNER operating on the East and West Coast main lines, the Settle to Carlisle line, accidents and railways in the Leeds and Bradford area.
