Robert Brainard Corey (August 19, 1897 – April 23, 1971) was an American biochemist, mostly known for his role in discovery of the a-helix and the ß-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 a-helix and ß-sheet are two structures that are now known to form the backbones of many proteins.
