Jon Eisenson, 1907 - 2001 Jon Eisenson was born in 1907 in new York City. He earned his Bachelor's Degree from the City College of New York in 1928 and his Master's and Doctoral Degrees from Columbia University. During World War II, Eisenson developed a test to show aphasia in soldiers with severe brain damage. Aphasia is a disorder that involves difficulty in speaking or understanding language, a problem which is a direct result of brain disease or injury. He also did research with children who stuttered, saying that the anxiety that found in home life is what caused the speech impediment and if they could ease he anxiety, the stutter would dissolve. During his career, Eisenson established the diagnostic category of childhood aphasia, and established the Institute for Childhood Aphasia in 1962. He wrote poetry, children's books, books on aging and books on aphasia, including, "Adult Aphasia" and "Aphasia Disorders in Children." He was an emeritus professor of speech at Stanford University, where he established his Institute. Jon Eisenson died on July 25, 2001 at the age of 93.
