The title Baron Barnard, of Barnard Castle in the Bishoprick of Durham, was created in 1698 in the Peerage of England. It was granted to Sir Christopher Vane, who had previously served as a Member of Parliament. The third Baron was created Viscount Barnard and Earl of Darlington. The third Earl was then made Duke of Cleveland. In 1891, however, at the death of the fourth duke, all of the higher titles became extinct, and only the barony remained, passing to Christopher William Vane.
Barnard was quite photogenic and enjoyed the media attention following the operation, which made him famous around the world.
Barnard continued to perform heart transplants: a transplant operation was conducted on 2 January 1968, and the patient, Philip Blaiberg, survived for 19 months.
Barnard divorced in 1982, and retired due to stiffness brought on by rheumatoid arthritis in his hands in 1983, mostly due to activities on his ranch in the Great Karoo.
