Carl William Hansen (11 October 1872 – 3 August 1936) was a Danish dairy farmer, Luciferian, wandering bishop, and occultist.
Born in Copenhagen and first initiated into Martinism in 1898 by Alphonse Wallen, Hansen used the pseudonym Ben Kadosh to publish Den ny morgens gry: verdensbygmesterens genkomst ("The Dawn of a New Morning: The Return of the World's Master Builder") in 1906.
[1] Inspired by the French Gnostic movement and such writers as Carl Kohl, his major interests seems to have been alchemy and astrology.
[3] In September 1921 Theodor Reuss issued fringe masonic charters to Hansen for Gnostic Primas, Memphis & Misraim, Ordo Templi Orientis and the Hermetic Brotherhood of Light.
[5] Biographies of Hansen have been written by Peder Byberg Madsen and Bjarne Salling Pedersen and included in the 2006 reissue of Den Ny Morgens Gry, Lucifer-Hiram, Verdensbygmesterens Genkomst.
