McGill War Records:

Wilder Penfield conquers seasickness

"Many famous contributors to psychology led lives outside of the laboratory that never
make it into textbooks but that students love hearing about. Consider
Wilder Penfield, perhaps the giant of 20th-century neuroscientists. He was an imposing
person — personally, intellectually, and physically. An athlete, he played
varsity football while at Princeton and then worked as an assistant coach. Princeton
lost a potential head coach and the world gained a prominent brain researcher
when he turned down a coaching promotion to accept a Rhodes Scholarship. Less
well-known than his work on the brain is his work on motion sickness. During
World War II, the Canadian government called upon him to run a crash program to
find a treatment to aid sailors and soldiers on voyages to Europe. So, with the help
of his associates, Penfield went on various rides at a Montreal amusement park to
find the ones that best mimicked the nausea-inducing movements of a ship at sea,
and then built a “ride” that best replicated that motion in a squash court at McGill
University. He tested the effects of various drugs on riders until he found one that
worked: thiobarbiturate."
