Pierre Gassendi

From A HISTORY OF UNITARIANISM, 1945 by Earl Morse Wilbur

" Distinguished men like Grotius, then living in exile in France, the liberal Calvinist Sorbière and the Catholic Mersenne, carried on amicable exchange of views with the brethren of Raków. "  
(pp. 424-5)

When Grotius returned to Paris in 1632 he became the centre of a circle of Polish youth, who seem to have been largely Socinians. Andrew Wiszowaty in the course of his wide travels had intimate relations not only with him but also with Gassendi, Mersenne and other distinguished men. One of the most interesting of these was Samuel Sorbière, member of a prominent Calvinist family, who had been designed for the Protestant ministry but had left it for medicine, and finally ended a Catholic. Wiszowaty made his acquaintance, interested him in Socinian thought, and for several years corresponded with him. Ruar thought him very near the Socinian camp, and by the Calvinists he was even charged with being a Socinian. [etc]
