Pyotr Demianovich Ouspensky (1878–1947) Russian
philosopher and interpreter of his
guru, G.I.
Gurdjieff. Being attracted to
theosophy early in his
life, he published several books one of which was titled Tertinum Organum (Third
Work) which covered such topics as
time,
space, the cosmos and
Eastern and Western
philosophies. It was at this same
time that he became associated with
Gurdjieff and became a disciple of his until 1924. From then on, Ouspensky conducted lectures in
England while continuing to write until his
death in 1947.
