FUDOFSI ceased to exist at some point during World War II. However, in 1947 some of its members contacted each other and tried to establish a new organisation.
Hans-Rudolf Hilfiker and
R. Swinburne Clymer (1878–1966) tried to create a
Worldwide Alliance of Rosicrucian Orders. In Rio de Janeiro, Clymer successfully merged his organisation with Krumm-Heller's. Hilfiker and Clymer had a meeting on May 7, 1947 and also on June 5, 1948, in Zürich, Switzerland at the hotel Baur au Lac. The
Fraternitas Rosae Crucis official biography of
Emerson Myron Clymer, son of R. S. Clymer, describes him as
Supreme Grand Master of FUDOFSI after his father's death, so it is possible that the
Fraternitas Rosae Crucis considers FUDOFSI to have survived later. ==See also==
