Johan Georg Ræder

Johan Georg Ræder was born in Kristiania (now Oslo) and graduated in medicine in June 1915. Already from 1912, while still a student, he was a candidate at the department of diseases of the eye at Rikshospitalet. After graduation he travelled to Angola, then a Portuguese colony, where he served for one year as a physician to the South Atlantic Whaling Company.

After returning to Norway he held internships at the Rikshospitalet, and during the years undertook postgraduate studies at the universities of Copenhagen, Paris, Freiburg im Breisgau, Graz, and Halle an der Saale. He was assistant physician at the department of diseases of the eye at Rikshospitalet from 1921, and from 1920 to 1925 held a scholarship in ophthalmology and physiological optics at the University of Oslo. In 1924 he became a licensed specialist in diseases of the eye, and that year obtained his medical doctorate. From June 1930 he was physician, and from 1931 head physician at the newly established department for diseases of the eye at Ullevål Sykehus in Oslo. From the mid 1930's failing health caused him to reduce his workload, and he retired in 1942.

A passionate hunter an lover of outdoor life, Reader visited Africa several times and wrote books about his experiences.
