Adil El Tayar had worked around the world including in Saudi Arabia, Sudan as well as at St Mary's and St George's hospitals in London.
His family said Dr El Tayar died on 25 March at West Middlesex University Hospital in Isleworth, west London.
Dr El Tayar graduated from the University of Khartoum in 1982 and moved to the UK in 1996, where he then studied at the University of West London.
He worked as a transplant surgeon at St George's Hospital, Tooting, before moving to Saudi Arabia in 2007, where he spent three years working at the King Fahd General Hospital in Jeddah.
In 2011, Dr El Tayar moved back to his native Sudan to help establish a transplant program and worked at the Ibn Sina Hospital, Khartoum.
Following this, he worked again at St George's Hospital as a locum surgeon.
Consultant surgeon at St George's, Abbas Ghazanfar paid this tribute to his former colleague:
He was a noble human being ... Mr El Tayar was a very hard working and dedicated surgeon who gave the precious gift of life to so many people around the world by his excellent transplanting skills ... he was an excellent colleague, a truly humble soul.
