G. I. Gurdjieff's teaching and practice inspired the formation of many groups organized as Foundations, Institutes, and Societies many of which are now connected by the International Association of the Gurdjieff Foundations (IAGF).
[5] There is a network of partner foundations around the world, including in North, Central and South America as well as Europe.
The president of the Gurdjieff Foundation of New York was Henry John Sinclair, 2nd Baron Pentland, Lord Pentland from its formation until his death in 1984.
It was then led by Dr. William J. Welch until his death in 1999, after which it was led jointly by Paul Reynard, a painter and teacher of Gurdjieff Movements, and Frank R. Sinclair, author of Without Benefit of Clergy and Of the Life Aligned, until Reynard's death in 2005.
Frank R. Sinclair continued as president until 2011 and is currently president-emeritus.
