Along with Maurice Wilkins, James D. Watson (born 1928) and Francis Crick (1916–2004) shared the 1962 Nobel Prize in Medicine for discovering the function and structure of DNA, providing the prime impetus for further research in the emerging fields of molecular genetics and biochemistry. Matte-finish 7.5 x 9.5 photo of Watson and Crick posing with large DNA model, signed in black ink “James D. Watson” and “Francis Crick.” Small, faint crease to top edge, otherwise fine, clean condition. A most desirable duo seldom seen in signed photos of this size and quality! R&R COA.
