Prem Nath Satsangi was a general practitioner in Gidea Park, Romford, Essex. He was born in Basti in Uttar Pradesh, India in July 1932 and studied medicine at King George’s Medical College, Lucknow, qualifying with a MB BS degree in 1954. He decided on a career in surgery and was awarded a masters degree in general surgery in 1956 with a thesis on the amino acid content in the skin and its relation to wound healing. The thesis formed the basis of a paper in the *Indian Journal of Medical Sciences*, published in 1960 (‘Aminoacid content of keloid’ *Indian J Med Sci*. 1960 Jun;14:531-3). In 1961 he left India for England, to complete his higher training in surgery. He held junior appointments at hospitals across England and gained his fellowship of the Royal College of Surgeons of Edinburgh in 1966 and of the Royal College of Surgeons of England in 1967. He was a registrar in thoracic surgery in Preston, and a general surgical registrar at Ashington General Hospital in Northumberland and at Victoria Hospital, Romford. His paper ‘Rupture of the trachea and bronchi by closed injury’ was published in *Thorax* in 1966 (*Thorax*. 1966 Jan;21[1]:21-7). He completed a series of locum senior registrar and consultant appointments in England and Scotland, before moving into general practice. He worked as a single-handed practitioner in Gidea Park, Romford for 30 years and was well-respected by his patients and colleagues in the area for his dedication to his patients. In his holidays he worked in Scotland in locum consultant surgical appointments until 1987. He developed a love for the country, the people and the landscape, especially the Highlands and the Western Isles. He formally retired in 2002, but in his retirement worked in general practices throughout London. He also studied French and German to diploma level and continued to attend medical meetings across the globe until 2019. He particularly liked contributing to meetings of the Anglo-German Medical Society and attending gastroenterology and hepatology meetings in Switzerland, France and Germany. He was married to Nirmal, an anaesthetist, until her death in 2009. He died on 10 November 2020 at the age of 88 and was survived by their two sons, the elder, Madhu, an academic in social sciences at the University of Glasgow, and the second, Jack, a professor of gastroenterology in Oxford and Edinburgh, and four grandchildren, who remember a loving and generous grandfather.
