Born in 1901 in Görlitz, Germany, Reinhold Ebertin was the son of a physician who dabbled in astrology. Initially a follower of Alfred Witte (founder of the Hamburg School of Uranian astrology), Ebertin eventually broke away to form his own discipline: Cosmobiology. Unlike traditional astrology, cosmobiology focuses exclusively on the midpoints of planets and fixed stars, discarding houses (often) and using the 90° dial for analysis.
Ebertin’s major work, first published in German in 1940 (and repeatedly expanded), was later translated into English by A.G. Roeder in the 1970s. It remains in print today, thanks to the American Federation of Astrologers (AFA) and Ebertin Verlag.
