He attended the first International Symposium on Cholinergic Mechanisms (1970) (Skokloster, Sweden) and was an active member of the International Advisory Board for many years. An obituary paper by Herbert Zimmermann and Frode Fonnum retraces his achievements.
Wilson BWBarry Wilson died on March 27th 2014. Barry was a major contributor to the cholinesterase field and attended many international cholinesterase meetings. He had multiple interests with the cholinesterases and related esterases extending from carbamate protection of organophosphate exposures and human blood cholinesterase variations to neurotoxic esterases. Being in an avian science department, he worked extensively with bird cholinesterases. His larger endeavors toward environmental protection were at the forefront.
Wilson IBIrwin B Wilson was born on May 8, 1921 and passed away on Sunday, December 22, 2013. Irwin Wilson described features of the active site of acetylcholinesterase in collaboration with Felix Bergmann and David Nachmansohn. Irwin B. Wilson and Richard J. Kitz described the inhibition of acetylcholinesterase in two steps by covalently acting molecules which rapidly and reversibly bind to the active site of the enzyme. Next, the reversible complex undergoes covalent fixation at a characteristic rate. Wilson and Sara Ginsburg synthetized the 2-PAM (pralidoxime) a reactivator of cholinesterase inhibited by organophosphates simultaneously and independently of Green AL. See: Petroianu 2013. Important steps in his carrier are described in the -Irwin Wilson lecture- given by Israel Silman and Joel L Sussman in 1998 at the 6th meeting on cholinesterase in San Diego.
