Pir Vilayat Inayat Khan (1916 -2004) was the eldest son of Sufi Murshid Hazrat Inayat Khan and Ora Ray Baker. As his father's successor, Pir Vilayat served as head of the Sufi Order International for 50 years. Born in London, England, Pir Vilayat Inayat Khan was educated at the Sorbonne, Oxford, and L'Ecole Normal de Musique de Paris. During World War II he served in the British Royal Navy on a mine sweeper and participated in the invasion at Normandy. His sister, Noor-un-Nisa Inayat Khan served in the French Resistance as a radio operator and was executed at Dachau. After the war, Pir Vilayat pursued his spiritual training by studying with masters of many different religious traditions throughout India and the Middle East. While honoring the initiatic tradition of his Sufi predecessors, Pir Vilayat continually adapted traditional Eastern spiritual practices in keeping with the evolution of Western consciousness, psychology and science. He initiated and participated in many international and interfaith conferences promoting understanding and world peace.
