Charles Webster Leadbeater was influential early in the development of mixed gender Freemasonry and at the peak of the Theosophical influence. Annie Besant was also a Theosophist and she also introduced Theosophical elements into her Freemasonry, but Leadbeater (together with Wedgewood) went way over Besant in that regard.

Leadbeater wrote a lot, but it seems that his bibliography contains just two books about Freemasonry, both published in 1926. The first is called "Glimpses of Masonic History" (later: Ancient Mystic Rites). The second "The Hidden Life in Freemasonry".

Combining seership with science, in "Glimpses of Masonic History" Leadbeater presents an absorbing, in-depth, study of the mystery schools of Egypt, Greece, Judea, the Knights Templar of the Middle Ages, and the emergence of Co-Masonry in the twentieth century.
