Walter Somerville CBE (1913–2005) was an Irish cardiologist who played a leading role in heart surgery at London's Middlesex and Harefield hospitals.

[4] In 1943, he was seconded to the US War Department, where he helped with preparations for the invasion of Japan, during which he was badly burned, and left with scars on his face, feet and legs.

[5] After being demobbed and returning to Britain, Somerville took a refresher course at Hammersmith Hospital, led by renowned cardiologist Paul Wood.

After negotiating a better publishing deal with BMA Publications, he used the money towards the purchase of a house in London's Fitzroy Square, which was to become home to the British Cardiac Society.

The following year he was appointed by Queen Elizabeth as a consultant to the King Edward VII Convalescent Home in Osborne House on the Isle of Wight.
