Bhāskara II
Madhava laid the foundations for the development of calculus, which were further developed by his successors at the Kerala school of astronomy and mathematics. (Certain ideas of calculus were known to earlier mathematicians.) Madhava also extended some results found in earlier works, including those of Bhāskara II. It is uncertain, however, whether any of these ideas were transmitted to the West, where calculus was developed independently by Isaac Newton and Leibniz.
