Sir Henry Head, FRS was an English neurologist who conducted pioneering work into the somatosensory system and sensory nerves. Much of this work was conducted on himself, in collaboration with the psychiatrist W. H. R. Rivers, by severing and reconnecting sensory nerves and mapping how sensation returned over time. Head-Holmes syndrome and Head-Riddoch syndrome are named after him.

William Halse Rivers Rivers was an English anthropologist, neurologist, ethnologist and psychiatrist known for treatment of First World War officers suffering shell shock, so they could be returned to combat. Rivers' most famous patient was the war poet Siegfried Sassoon, with whom he remained close friends until his own sudden death.
