Gabriel Vahanian (in Armenian Գաբրիէլ Վահանեան) (24 January 1927 – 30 August 2012) was a French Protestant Christian theologian who was most remembered for his pioneering work in the theology of the "death of God" movement within academic circles in the 1960s, and who taught for 26 years in the U.S. before finishing a prestigious career in Strasbourg, France.
Vahanian was born Gabriel Antoine Vahanian in Marseille, France, to a family of refugees of the Armenian Genocide. He received his French baccalaureate (baccalauréat) in 1945 from the Lycee of Valence in France and then graduated from the Protestant Faculty of Theology in Paris, his Master's Degree in Theology in 1950 from Princeton Theological Seminary, and his Ph.D. in 1958, also from PTS. His dissertation was entitled "Protestantism and the Arts."
He then served on the faculty of Syracuse University for 26 years. At Syracuse he held the Eliphalet Remington chair in Religion from 1967 to 1973, and then the Jeanette Kittredge Watson chair in Religion from 1973-1984, and founded in 1968 and was the first director of the graduate studies program in religion.
He moved in 1984 to the Université des Sciences Humaines de Strasbourg, for a post considered France’s most prominent theological professorship of Protestantism. He ended his career as Professor Emeritus of Cultural Theology at the Université Marc Bloch and its successor, the combined University of Strasbourg.
