Peter Daniel Anthonisz was born on 25 June 1822 in Galle,[4] the first son of ten children, to Leonardus Henricus Anthonisz (1796–1845), the Chief Clerk of the Galle Customs,[5][6] and Susanna Dorothea née Deutrom (1805–1872).[6][7] In 1838 at the age of sixteen he was appointed as a medical sub-assistant at the Military Hospital in Galle.[1][6] The following year he was sent to study at the Bengal Medical College in Calcutta, returning in 1843.[6] In the 1850s he worked as a physician at the Military Hospital in Colombo (his patients included the Governor Sir William Henry Gregory).[6] In June 1856 he travelled to England, where he obtained an M.R.C.P. (Membership of the Royal College of Physicians, London)[8] and was elected a Fellow of The Royal College of Surgeons of Edinburgh (FRCSEd) on 1 April 1857.[6] He returned to Ceylon in 1858, where in August he was appointed to as the Colonial Surgeon of the Southern Province, a post he remained at until 1880.[6] During this period he travelled to Europe, where in 1863 he received a Doctorate in Medicine from the University of St Andrews (St Andrews, Scotland).[6] In 1881 he left to do further studies. Upon his return in 1883 he took up the position of Chief Medical Officer at Galle.[6] Anthonisz was the first doctor to successfully undertake oesophagotomy and ovariotomy[9] surgery in the country. His oesophagotomy was reportedly the first recorded in British medical annals.[6][10][11]
