Robert Brainard Corey (August 19, 1897 – April 23, 1971) was an American biochemist, mostly known for his role in discovery of the α-helix and the β-sheet with Linus Pauling. Also working with Pauling was Herman Branson. Their discoveries were remarkably correct, with even the bond lengths being accurate until about 40 years later. The α-helix and β-sheet are two structures that are now known to form the backbones of many proteins.
A childhood cancer victim, Corey received his undergraduate degree from the University of Pittsburgh, and his Ph.D. in Chemistry from Cornell University (Marsh, p. 52-53).
At Caltech, the trio (Pauling, Corey and Branson) published a series of 8 articles in the Proceedings of the National Academy of Sciences (PNAS).
