Alan Woodworth Johnson FRS (20 September 1917 – 5 December 1982) was a British professor of biochemistry.
[1] During Johnson's years at Cambridge he worked on the biochemistry of various natural products, including vitamin B12, tropolones, aphid pigments,[2] and plant germination factors.
Together with Daniel Douglas Eley and Cyril Clifford Addison, he designed and oversaw the construction of a new chemistry building, which opened in 1960.
After working on studies of vitamin B12, synthesis of porphyrin and corrin, and the structures of the phytochemicals primisterin and maytenone, Johnson resigned from the University of Nottingham in 1968.
He gave popular lectures on Sex and Violence in the Insect World to chemistry departments across the UK.
