Axel Munthe sibling Anna Munthe-Norstedt
Early life
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 Steps 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.Parents and siblings
