His grandfather Sir Bosdin Leech had overseen the construction of the Manchester Ship Canal. Leech was educated at Lakefield and Vernon Preparatory Schools before going to Salmon Arm High School. At a young age he was interested in natural history and was influenced by Ralph Hopping, a forest entomologist. He then obtained a BSc from the University of British Columbia, Vancouver in 1933 and an MSc from the University of California, Berkeley where he studied entomology with E.O. Essig.[1] He married Frances Orchid Quail in 1936.
