Bryant Tuckerman died on May 19, 2002, at the age of 86.

Dr. Tuckerman obtained a Ph.D. in topology from Princeton University.  He taught mathematics at Cornell University and Oberlin College.  Then he worked for five years at the Institute for Advanced Study with John von Neumann on applications of early computers.  He spent the remaining 35 years of his professional career at the IBM T. J. Watson Research Center in the Mathematics Department, where he received many awards for his pioneering work on applications of computers for scientific calculations, number theory, cryptography and data security.  In 1971 he published what was then the largest known prime number, the "24th Mersenne prime" 219937-1.  He was a key member of the IBM team that developed the "Data Encryption Standard" DES, which was officially adopted by the U.S. government in 1976.  In 1983, 1988 and 2002, he was a coauthor (with Brillhart, Lehmer, Selfridge and Wagstaff) of a book on factorizations of numbers bn+1.
