One of the very few mathematicians who were also prominent in government (others being Johan de Witt and Isaac Newton (after a fashion) and more recently Paul Painleve (French Prime Minister in the early 1900's), he is often credited as a father of Actuarial Mathematics (insurance mathematics) together with Johan de Witt (then Governor of the Dutch Republic). This was related to the new mercantile enterprizes of the new Dutch Republic which required cooperations between merchants and insurance of their common enterprizes. This also spawned the first stock exchange in Amsterdam (1602?):

However he was introduced to mathematics at Leiden by his teacher van Schooten . From 1654 until 1663 he worked on mathematics as part of van Schooten geometry research group at Leiden. From 1663 he worked in various roles for the Amsterdam City Council. He served for 30 years as burgomaster of Amsterdam being first appointed in 1672. All of Hudde's mathematics was done before he began to work for the city council in 1663. Van Schooten edited and published a second two-volume translation of Descartes 's (1659-1661) which contained appendices by de Witt , Hudde and van Heuraet Hudde worked on maxima and minima and the theory of equations. Hudde gave an ingenious method to find multiple roots of an equation which is essentially the modern method of finding the highest common factor of a polynomial and its derivative. He was the first to treat the coefficients in algebra without considering whether they were positive or negative in De reductione aequationum.
