Papworth Hospital is celebrating the 40th anniversary of the first successful heart transplant in the UK.
The transplant was performed at the newly named Royal Papworth on patient Keith Castle by surgeon Sir Terence English on 19 August 1979.
Mr Castle left hospital to go home in October 1979 and lived for five years post-transplant.
His survival without the operation would have been a matter of weeks.
More than 8,000 heart transplants have been carried out in the UK in the last 40 years.
Surgeons at Papworth have performed about 1,500 of those, including 45 this year.
A special anniversary event is taking place at Papworth today, which is now based on the Cambridge Biomedical Campus, after moving from the old site at Papworth Everard.
