Christopher Polge Dies
Christopher Polge, who died on August 17 aged 80, attained scientific eminence at a remarkably early age: his discovery, whilst still a doctoral student, of how to preserve living cells and tissues at very low temperatures solved a long-standing and intractable problem in biology.
This breakthrough not only formed the basis for the new science of cryobiology but has also had profound and continuing practical implications for agriculture and medicine.
