David Ezra Green was born in Brooklyn, New York, on August 5, 1910. He attended the public school system there and apparently was indifferent to his studies in both his grade-school and high-school days. About his early education Green explained, “As I look back, school per se exerted little influence on me. My friends and my family were the principal catalysts in my development. There was not a single teacher in high school that fired or inspired me, though I respected them all as competent individuals. Curiously enough, courses in science did not particularly interest me. I hardly know why I avoided them in high school.” Interestingly the Book of Knowledge, an encyclopedia popular during that period, became Green’s bible. Its 20 volumes served as sources of information on subjects ranging from the arts to the sciences. His father loved learning, and it was from him that Green acquired an interest in books, ideas, and self-development.
In 1928 Green enrolled in New York University at the Washington Square campus and initially intended to study medicine. After taking the premedical-school curriculum for two years, however, he realized that the field of medicine did not interest him. Fortunately he was offered a student assistantship in the Department of Biology, and there he completed his undergraduate studies in 1931. A very important event was his summer experience at Woods Hole, where he associated with Professor Robert Chambers, the famed cell physiologist, and later with Professor Leonor Michaelis. Apparently the close association with Michaelis inspired Green and aroused his desire to explore more fully the mysteries of biological oxidations.
Green received a master’s degree in 1932 at New York
