Sir Henry Dale

Died 23 Jul 1968 at age 93 (born 9 Jun 1875). Sir Henry Hallett Dale was an English biologist and physiologist whoisolated(1914) the neurotransmitter acetylcholine from ergot fungi. In 1936 he shared the Nobel Prize for Physiology or Medicine (with the German pharmacologist Otto Loewi) for discoveries in the chemical transmission of nerve impulses.
