First Edition. Evans, best known for discovering vitamin E and human growth hormone, collaborated with zoologist Olive Swezy in research on human chromosomes in the 1920s, a time when the exact number of chromosomes per cell was still unknown. “For this study Evans personally obtained exceptionally well-preserved material by attending, at San Quentin prison, executions of criminals whose bodies were not to be claimed by relatives. Swezy did most of the counting, from thin serial sections . . . The count of 48 chromosomes in each cell, published by Evans and Swezy, was unfortunately incorrect; it is now certain that 46 is the correct number. In 1969, to a gathering of scientific friends, Evans explained that semidetached portions of two chromosomes had been counted as separate units” (Corner, p. 171).
