Cancer researcher Sidney Mirvish died at age 86. His research into nitrosamines and carcinogenesis led to changes in the way lunch meats, hot dogs and sausages were made.

Mirvish served as professor emeritus in the Eppley Institute for Research in Cancer and Allied Diseases at the University of Nebraska Medical Center, where he was faculty member for 46 years. Mirvish died due to complications following emergency surgery on Aug. 18, 2015.

Ken Cowan, director of the Fred & Pamela Buffett Cancer Center, called him “an internationally recognized leader in nitrosamines and carcinogenesis who helped build the scientific reputation of UNMC and the Eppley Institute.”
