“I’m very touched by it all, and it’s making a difficult time a lot easier.”

He said his dad was born in Sierra Leone on 1 October 1944, graduated in law from the University of Oxford and trained in medicine at St Bartholomew’s Hospital in London.

The surgeon was also known for developing the B-Lynch brace suture, a technique for severe postpartum haemorrhage that helped save the lives of mothers across the world, Josh added.

Josh described him as a “devoted father, grandfather, mentor, colleague and friend”.

The GP said: “It was a strange thing to see my own surname appear as an EMQ option in my fifth-year exam paper.

“His legacy lives on in the doctors he mentored, the women whose lives he helped save, the family he loved, and the countless people worldwide who continue to benefit from his work.”

He also founded the Myrtle Peach Trust Charity for the prevention and treatment of cervical and ovarian cancer.

Dr Ian Reckless, MKUH’s chief medical officer, said: “He was an inspiring force for good who was pivotal to the development of our hospital.

“Patients and colleagues alike remember him as a compassionate and hard-working person as well as an innovator who was driven by a determination to provide safe, quality care.”

Nandini Gupta, consultant and the hospital’s divisional director of obstetrics and gynaecology, said: “Prof Balogun-Lynch was there right from the start of the hospital until he retired in 2010.

“He was an excellent colleague who was always available to advise and help with difficult cases.

“He is rightly celebrated internationally for his innovative and pioneering approach, including his introduction of the B-Lynch suture, which is still being used today.”
