Margaret Alice Kennard (September 25, 1899—December 12, 1975) received her doctoral degree in 1930, from Cornell University. She was a neuroscientist who principally studied the effects of neurological damage on primates. Her work led to the creation of the Kennard Principle, which posits a negative linear relationship between age of a brain lesion and the outcome expectancy: in other words, that the earlier in life a brain lesion occurs, the more likely it is for some compensation mechanism to reverse at least some of the lesion's bad effects. She earned a Rockefeller Traveling Fellowship for study in Western Europe from 1934 to 1936. She also studied the effects of stimulants and cortical depressants on monkeys with brain damage.
