Prince Ivan Sergeyevich Gagarin SJ was a Russian Jesuit, known also as Jean-Xavier after his conversion from Orthodoxy to Roman Catholicism. As a member of the hereditary Russian nobility, he was of the Gagarin family, which traces its origin to the medieval rulers of Starodub-on-the-Klyazma. He was the founding editor of Études.
