Joseph Vincent Brady (March 28, 1922 – July 29, 2011) was a behavioral neuroscientist at the Walter Reed Army Institute of Research in the United States. While at the Walter Reed Institute he performed the experiment "Ulcers in Executive Monkeys" that suggested a link between stress and peptic ulcers. This research was significant in establishing the idea that stress was a physical illness, with important influence in the development of Psychology and Neuroscience.
After the launch of Sputnik he became responsible for training monkeys for the space program, in particular Ham. Ham was the first hominid in space and rode aboard a Redstone launch vehicle. The training of Ham was performed in a similar way to his earlier studies on executive monkeys.
He founded the Programmed Environment Research Center as well as the Division of Behavioral Biology in the Department of Psychiatry and Behavioral Sciences at the Johns Hopkins University School of Medicine. He continued to work there for three decades and received the P.B. Dews Lifetime Achievement Award in Behavioral Pharmacology in 2004. Based upon his seminal work in programmed environments, he continued to explore the potential application of behavioral management principles to long-duration space flight.
In 2011, Brady was honored for his 50 years of leadership of the Institutes for Behavior Resources, Inc. located in Baltimore, Maryland.
He died in July of that year of cardiorespiratory arrest.
