Short Summary
George Wald was an American scientist renowned for his groundbreaking research on vision, particularly the biological mechanisms of the eye. He was awarded the Nobel Prize in Physiology or Medicine in 1967 for his discoveries concerning the physiological and chemical processes involved in the visual cycle. Wald's work significantly advanced the understanding of how light affects the eyes and laid the groundwork for future research in the field of vision. His contributions to science and his advocacy for social and political issues made him a highly respected figure in both academic and public circles.
Early Life & Education
George Wald was born on November 18, 1906, in New York City to Jewish immigrant parents. His father, Ernest, was a tailor, and his mother, Frances, was a homemaker. Wald displayed a keen interest in science from a young age, which led him to pursue higher education in the field. He attended Brooklyn's Erasmus Hall High School before enrolling at New York University, where he earned his bachelor's degree. Wald subsequently studied at Columbia University, obtaining his Ph.D. in Zoology in 1932. During his doctoral studies, he worked under the guidance of Selig Hecht, a prominent physiologist, who greatly influenced his future research interests in vision.
Career Highlights
After completing his Ph.D., George Wald was awarded a National Research Council Fellowship, allowing him to travel to Europe. There, he worked with Otto Warburg in Berlin and Paul Karrer in Zurich, gaining invaluable experience in biochemistry. Upon returning to the United States, Wald joined Harvard University in 1934, where he embarked on his pioneering research into the biochemical basis of vision. His work at Harvard spanned several decades, during which he made significant discoveries, such as identifying vitamin A as a crucial component of the visual cycle. Wald's career was marked by a deep commitment to both scientific inquiry and social activism.
