Franois Rozier (ordained priest but lacked a vocation ) studied in the college at Villefranche-sur-Sane, and preferred to devote himself to science.
He was ordained priest but lacked a vocation and thus became manager of his elder brother's estate in the Sainte-Colombe district on the banks of the Rhone, near Vienne, after their father's death in 1757. Rozier studied in the Jesuit college at Villefranche-sur-Saone and entered the Saint-Irenee seminary in Lyon. Refusing to enter a more major seminary, he preferred to devote himself to science.
