He remained actively connected to the company in his retirement in 1995. In 1982 Alan was awarded the distinction of a Doctor of Science degree by his alma mater, Cambridge University, and in 1990 his research was recognized by his being made a Quatercentenary Research Fellow of Emmanuel College, Cambridge.
