Roy Calne, a pioneer of organ transplantation who led Europe’s first liver transplant operation in 1968, has died aged 93. Calne’s family said he died late Saturday in Cambridge, England, where he was professor emeritus of surgery at Cambridge University. Born in 1930, Calne trained as a doctor at Guy’s Hospital in London and developed an interest in organ transplantation in the 1950s — partly inspired, he later said, by his father's work as a car mechanic.
