Wilf was awarded a D.Sc. at the early age of 36 years by the University of London for his work in heterocyclic chemistry, and in 1972 he changed his research field to studies of pteridine requiring enzymes associated with a variety of inborn errors of metabolism in children. This involved work on enzyme purification, cloning, mutation, expression, kinetics, and mechanisms. Since retirement, Wilf has been a Visiting Fellow in the JCSMR. He has written four books (Fused Pyrimidines, Part 1 -Quinazolines, Stereochemistry of Heterocyclic Compounds, Parts 1 and 2, and Purification of Laboratory Chemicals) in addition to having over 140 publications in his name. His awards include FRSC
