Edward ('Ted') F. Hancock (1921 - 2001) was an industrial chemist involved in the manufacture of medical drugs, first as an apprentice with Boots Chemists (1938 to 1941), then after qualifying he joined a group at University of London devising a method for the large scale production of penicillin. Later he put this into practice with Glaxo Laboratories, first at Barnard Castle, then at Ulverston where he continued until his retirement. As a developing amateur entomologist his interest in Microlepidoptera was stimulated by a chance professional meeting in Ulverston with John Heath, the founder of this series, as well as of the Biological Records Centre. He produced the first draft of this volume in spite of being incapacitated by a series of strokes, which finally resulted in his death in February 2001. [see obituary in Ent.Rec. 113, 171-174].
