Louis Massignon

Louis Massignon (25 July 1883 – 31 October 1962) was a French Catholic scholar of Islam and a pioneer of Catholic-Muslim mutual understanding. He was an influential figure in the twentieth century with regard to the Catholic Church's relationship with Islam and played a role in Islam being accepted as an Abrahamic faith among Catholics.

Although a Catholic himself, he tried to understand Islam from within and thus had a great influence on the way Islam was seen in the West; among other things, he paved the way for a greater openness to dialogue inside the Catholic Church towards Islam. Some scholars maintain that his research, esteem for Islam and Muslims, and cultivation of key students in Islamic studies largely prepared the way for the positive vision of Islam articulated in the ''Lumen gentium'' and the ''Nostra aetate'' at the Second Vatican Council.
