Carl Kellner is reputed to have developed the Ritter-Kellner process while working for Baron Hector Von Ritter-Zahony in 1876.[1] In 1889 he established the Kellner-Partington paper pulp Co[2] in association with Edward Partington.

The process for making caustic soda and chlorine by electrolysis of brine using a mercury electrode was developed independently by Mr Hamilton Y. Castner and Dr Carl Kellner in 1892. They established the Castner Kellner company jointly to exploit their patents in 1895.[3][4]

It is not known when he obtained his doctorate but he used the title of PhD from 1895.[5]

Freemasonry and esotericism

Kellner had become a Freemason in 1873, being initiated at the Humanitas Lodge on the Austro-Hungarian border, taking the motto of Brother Renatus.[6] In 1885, Kellner met the Theosophical and Rosicrucian scholar, Dr. Franz Hartmann (1838–1912). He and Hartmann later collaborated on the development of the "ligno-sulphite" inhalation therapy for tuberculosis, which formed the basis of treatment at Hartmann's sanitarium near Saltzburg. During this period Kellner became interested in the more esoteric aspects of Freemasonry, joining John Yarker's Rite of Memphis-Misraim. Hartmann's obituary of Kellner describes that in 1902 Kellner

"...was personally initiated in Manchester by Brother Yarker into the 96°, and made Sovereign Honorary General Grand Master of our Order"

During extensive travels in Europe, America, and Asia Minor, Kellner claimed to have come into contact with three adepts (a Hermetic Brotherhood of Light. These adepts are attributed with having initiated Kellner into the use of sexual magick (sometimes referred to as 'the sexual current' by ritual magicians). Kellner was also influenced by a French followers of the American occultist Paschal Beverly Randolph.

During the course of his esoteric studies, Kellner believed that he had discovered a "key" which offered a clear explanation of all the complex symbolism of Freemasonry, and, Kellner believed, opened the mysteries of nature. Kellner developed a desire to form an Academia Masonica which would enable Freemasons to become familiar with all existing Masonic degrees and systems.

Ordo Templi Orientis

In 1895, Kellner began to discuss his idea for founding this Academia Masonica with his associate

Due to the regulations of the established grand lodges which governed Regular Masonry, women could not be made Masons and would therefore be excluded by default from membership in Ordo Templi Orientis. Reforming the Masonic system to allow the admission of women may have been one of the reasons that Kellner and his associates resolved to obtain control over one of the many rites of Masonry; possibly because of wishing to incorporate the practice of sex magic. They may have believed that sex magic was "...the key to all the secrets of the universe and to all the symbolism ever used by secret societies and religions."[7]

The discussions between Reuss and Kellner did not lead to any positive results at the time, because Reuss was very busy with a revival of the Order of Illuminati along with his associate Leopold Engel of Dresden. Kellner did not approve of the revived Illuminati Order or of Engel. According to Reuss, upon his final separation with Engel in June 1902, Kellner contacted him and the two agreed to proceed with the establishment of Ordo Templi Orientis by seeking authorizations to work the various rites of high-grade Masonry. Reuss and Kellner together prepared a brief manifesto for their order in 1903, which was published the next year in The Oriflamme. However whether Kellner ever lived to see O.T.O. becoming more than just these early plans is debatable, since he died in 1905, not long after the first announcements were made.
