Big Pi Recipient, Marshall Nirenberg, passes into the Chapter Eternal 

Brother Marshall received the Big Pi for his efforts to decipher the genetic code. Dr. Nirenberg’s research identified codons – chemical units that specify the amino acids which construct DNA. The findings helped Dr. Crick and Dr. Brenner gain notoriety for unlocking DNA. Brother Marshall received the Nobel Prize in 1968 for his research.

Brother Marshall attended the University of Florida as an undergraduate. He joined Pi Lambda Phi in 1945. He is survived by his wife Myrna Weissman; his sister, Joan; and four stepchildren. His first wife, Perola Zaltzman Nirenberg, died in 2001.
