During the Fraternitas Saturni Lodge's Easter assembly on April 5th-6th 1969, members who had seceded from the Frankfurt F.S. (though without Walter Englert and his IO/O.T.O.), rejoined the Mother-Lodge. The new Grand Master of the United Grand Lodge Fraternitas Saturni was Walter Jantschik (born 1939), who had been a member since April 1964.
But Jantschik resigned from his post six months after taking office. Tirelessly he wrote Rituals, Essays, Meditations on Baphomet from then on.
The membership lists published below date from Jantschik's very short time as Grand Master. They bear his handwritten additions / corrections.
As far as I know, the last member mentioned on these lists died in October 2021.
