Answer by taking a quote from the following article:

Chogyam Trungpa (Wylie: Chos rgyam Drung pa; March 5, 1939 - April 4, 1987) was a Buddhist meditation master and holder of both the Kagyu and Nyingma lineages, the eleventh Trungpa tulku, a terton, supreme abbot of the Surmang monasteries, scholar, teacher, poet, artist, and originator of a radical re-presentation of Shambhala vision. Recognized both by Tibetan Buddhists and by other spiritual practitioners and scholars as a preeminent teacher of Tibetan Buddhism, he was a major figure in the dissemination of Tibetan Buddhism to the West, founding Vajradhatu and Naropa University and establishing the Shambhala Training method. Among his contributions are the translation of numerous Tibetan texts, the introduction of the Vajrayana teachings to the West, and a presentation of the Buddhadharma largely devoid of ethnic trappings. Trungpa coined the term crazy wisdom.

In 1973, Trungpa established Vajradhatu, encompassing all his North American institutions, headquartered in Boulder, Colorado. Trungpa also founded more than 100 meditation centers throughout the world. Originally known as Dharmadhatus, these centers, now more than 150 in number, are known as Shambhala Meditation Centers. He also founded retreat centers for intensive meditation practice, including Shambhala Mountain Center in Red Feather Lakes, Colorado, Karme Choling in Barnet, Vermont and Gampo Abbey in Cape Breton, Nova Scotia.  In 1974, Trungpa founded the Naropa Institute, which later became Naropa University, in Boulder, Colorado. Naropa was the first accredited Buddhist university in North America. Trungpa hired Allen Ginsberg to teach poetry and William Burroughs to teach literature.  Trungpa had a number of notable students, among whom were Pema Chodron, Allen Ginsberg, Peter Orlovsky, Anne Waldman, Diane di Prima, Peter Lieberson, John Steinbeck IV, Jose Arguelles, David Nichtern, Ken Wilber, David Deida, Francisco Varela, and Joni Mitchell, who portrayed Trungpa in the song "Refuge of the Roads" on her 1976 album Hejira. Ginsberg, Waldman, and di Prima also taught at Naropa University, and in the 1980s Marianne Faithfull taught songwriting workshops. Lesser-known students Trungpa taught in England and the US include Alf Vial, Rigdzin Shikpo (ne Michael Hookham), Jigme Rinzen (ne P. Howard Useche), Ezequiel Hernandez Urdaneta (known as Keun-Tshen Goba after setting up his first meditation center in Venezuela), Miguel Otaola (aka Dorje Khandro), Francisco Salas Roche, and Francesca Fremantle. Rigdzin Shikpo promulgated Trungpa's teachings from a primarily Nyingma rather than Kagyu point of view at the Longchen Foundation.
