Axel Martin Fredrik Munthe (31 October 1857 – 11 February 1949) was a Swedish-born physician and psychiatrist, best known as the author of The Story of San Michele, an autobiographical account of his life and work. He spoke several languages (Swedish, English, French, Italian fluently, and German at least passably), grew up in Sweden, attended medical school there, and opened his first practice in France. He was married to an English aristocrat and spent most of his adult life in Italy. His philanthropic nature often led him to treat the poor without charge, and he risked his life on several occasions to offer medical help in times of war, disaster, or plague. As an advocate of animal rights, he purchased land to create a bird sanctuary near his home in Italy, argued for bans on painful traps, and himself kept pets as diverse as an owl and a baboon, as well as many types of dog. His writing is light-hearted, being primarily memoirs drawn from his real-life experiences, but it is often tinged with sadness or tragedy, and often uses dramatic licence. He primarily wrote about people and their idiosyncrasies, portraying the foibles of both the rich and the poor, but also about animals.
Axel Munthe was born in Oskarshamn, Sweden, his family's home. His family was originally of Flemish descent, and settled in Sweden during the 16th century.
Munthe began college in 1874 at Uppsala University. While travelling in Italy in 1875, Munthe sailed in a small boat from Sorrento to the island of Capri. Climbing the Phoenician stairs to the village of Anacapri, he came upon a peasant's house and the adjacent ruin of a chapel dedicated to San Michele, and was immediately captivated by the idea of rebuilding the ruin and turning it into a home.
Munthe studied medicine in Uppsala, Montpellier and Paris (where he was a student of Charcot), and graduated as M.D. in 1880 at the age of 23. Though his thesis was on the subjects of gynaecology and obstetrics, Munthe was deeply impressed by Professor Jean-Martin Charcot's pioneering work in neurology, having attended his lectures at the Salpêtrière hospital. He later had a falling out with Charcot, and left the Salpêtrière denouncing his former teacher's work on hypnotism as fraudulent and scientifically unsound.
