Frank Bennett (1868 – November 1930) was an Australian chemist who was disciple of occultist Aleister Crowley a member and later head of Ordo Templi Orientis (O.T.O.)
During his earlier years he was involved in a number of esoteric movements, including the Theosophical Society and Universal Co-Freemasonry (now known as Co-Masonry: a mixed-sex version of Freemasonry).
In spite of his interest in Crowley, Bennett kept his ties with Co-Masonry and in 1911 emigrated to Australia, with the specific purpose of assisting in the foundation of Co-Masonic Lodges, a task he undertook with some success.
Frank Bennett’s interest in Co-Masonry waned, and he resigned from the Sydney Lodge, of which he was Past Grand Master, after a dispute over its management.
In July 1921, Bennett traveled to the recently founded Abbey of Thelema in Cefalù where he began personal studies under Crowley.
There he joined a small number of Thelemic luminaries including Leah Hirsig, Cecil Frederick Russell, Jane Wolfe, and others.
Following the closure of the Abbey of Thelema in Cefalù Aleister Crowley, Leah Hirsig and the other members of the small core group of Thelemites dispersed, and Frank Bennett slowly drifted out of contact with them.
A collection of Frank Bennett’s writings, including his "Magical Record" has been published, and he is also the subject of the full-length biographical study Progradior and the Beast.
