Grégoire de Saint-Vincent (1584–1667) was a Belgian Jesuit mathematician and philosopher known for his work in the field of mathematics, particularly for his contributions to the study of conic sections and his efforts in developing what would later be known as integral calculus. One of his notable achievements was his book "Typus universalis" (1647), where he worked on the idea of areas and volumes through geometric methods.
