On 12 July 1895, Jones became a member of the Hermetic Order of the Golden Dawn. He is perhaps best known for the pivotal role he played in the life of British
Aleister Crowley, stoking Crowley's youthful enthusiasm for
magick. On 25 January 1905, Jones married Ethel Melinda Baker at
Balham. She was the sister of Golden Dawn member Julian Levett Baker, who had introduced Crowley to Jones. Jones introduced Crowley to the
Golden Dawn, in which Jones was known by the
Latin magical motto Volo Noscere ("I want knowledge"). In 1906 Jones and Crowley founded the
A∴A∴, taking some of the lessons from their experiences with the Golden Dawn as well as the teachings of Crowley's
The Book of the Law, and incorporating them into their new order, which Crowley would head. Jones also contributed to Crowley's book of essays on and references for
Qabalah,
777 and other Qabalistic writings. In 1911 he unsuccessfully sued a newspaper, the
Looking Glass, for libellously associating him with Crowley. Jones retired as a chemist in 1939. ==Personal life==
