The beginnings of St Mark's Hospital were in a small room at No 11 Aldersgate Street where, in 1835, Frederick Salmon opened 'The Infirmary for the Relief of the Poor afflicted with Fistula and other Diseases of the Rectum'. There were just seven beds and in the first year 131 patients were admitted. Frederick Salmon was born in Bath in 1796 and served his apprenticeship in medicine there. He qualified at St Bartholomew's Hospital in 1817 and subsequently became a house-surgeon. In 1827, he was elected to a Surgeon's post at the Aldersgate Street Dispensary. However, Salmon resigned five years later, along with the rest of the medical staff, because of a dispute with the Management Committee about the method of choosing new staff. Tired of the restrictions of working within the establishment, Salmon decided to found his own institution to provide treatment for those conditions which were regarded as 'the most distressing that can afflict our common nature'. So the 'Fistula Infirmary', as it came to be known, was started.
