HGP meaning in Medical ?

Maurice Henry Pappworth (9 January 1910 – 12 October 1994) was a pioneering British medical ethicist and tutor, best known for his 1967 book Human Guinea Pigs, which exposed the unethical dimensions of medical research. Born and educated in Liverpool, Pappworth graduated as a Bachelor of Medicine, Bachelor of Surgery in 1932 from Liverpool University. After working in a series of junior medical positions, his applications for more senior posts were rejected. During the Second World War he served in the Royal Army Medical Corps. Having been unsuccessful in achieving a post in any well known London hospital after the war, he set up in London as an independent medical consultant and tutor.

Pappworth's teaching of postgraduate students had a profound effect on the Membership of the Royal College of Physicians (MRCP) examination pass rate, and his contact with junior doctors led him to investigate the ethics of medical research on humans. The publication of Human Guinea Pigs, which examined unethical medical research practices, exposed the subject to a wider audience and led to Pappworth's becoming persona non grata within the medical establishment for much of his career, but ultimately helped lead to stricter codes of practice for human experimentation.
