Comment
Dr. Martin Keith Johnson, born in 1930, died in Banstead, Surrey on the 9th November 2018. Dr. Johnson was a founder member of the British Toxicology Society.In the early years of his carrier he worked in the Biochemical Mechanisms Group run by Dr Norman Aldridge. He discovered the neuropathy target esterase (NTE) as an enzyme activity, inhibited by low concentrations of the neuropathic OP, mipafox, but resistant to an AChE-directed OP, paraoxon. A paper by Ted Lock, Andrew Smith and Paul Glynn retraces his achievements Obituary
