George Cornelius was a student of Gurdjieff in Paris, where Mr. Gurdjieff called him "The American".
George Cornelius also studied with P.D. Ouspensky, J.G. Bennett, Jane Heap and Rodney Collin.
Mrs. A.L. Staveley called Mr. Cornelius, "formidable" and "a strong meat - not for everyone". She said that Mr. Cornelius worked with those who had no group and who found it difficult to work within a group.
George Cornelius said "I teach discrimination" and drove away many who came to him. A friend of John Pentland and John Lester, George Cornelius was seen by many as a man, who kicked down doors, rode across boundaries and stepped on corns.
