Michael Rabin 
Michael O. Rabin Thomas J Watson, Sr. Professor of Computer Science at Harvard. 

Alonzo Church 
Alonzo Church 1903  1995 Fundamental contributor to theoretical computer science. Created lambda calculus, proved Church's Theorem that first order logic is undecidable, and proposed Church's Thesis (usually called the ChurchTuring Thesis) that effective computation is equivalent to recursion. 

Oswald Veblen 
Oswald Veblen 1880  1960 Once president of the American Mathematical Society, he is known for his work in topology, projective geometry, and differential geometry. 

Eliakim Moore 
Eliakim Hastings Moore 1862  1932 Contributed to algebra and group theory, as well as algebraic geometry, number theory, and integral equations. 

Hubert Newton 
Hubert Anson Newton 1830  1885 American scientist who was among the original members of the National Academy of Sciences. Contributed to pure mathematics, but his most important work was empirical and theoretical study of meteors. 

Michel Chasles 
Michel Chasles 1793  1880 French geometer and mathematical historian. Contributed to the development of synthetic geometry and introduced the notions of cross ratio, pencils, and involution. 

Simeon Poisson 
Simeon Poisson 1781  1840 French mathematician who received little regard from his contemporary countrymen. Now famed for his work in a number of fields, including probability and differential equations. 

Joseph Lagrange 
Joseph Lagrange 1736  1813 Selftaught prodigy, later a protege of Euler. Made crucial contributions to the nascent calculus of variations, and contributed to dynamics, mechanics, differential equations, astronomy, probability, and number theory. 

Leonhard Euler 
Leonhard Euler 1707  1783 Said to be the most prolific writer of mathematics of all time. The St. Petersberg Academy continued to publish unpublished work by Euler for fifty years after his death. Made fundamental discoveries in calculus (including the calculus of variations), mechanics, differential geometry, number theory, and complex analysis. 

Johann Bernoulli 
Johann Bernoulli 1667  1748 Swiss mathematician, among the first to explore calculus. His solution to the isoperimetric problem was foundational to the calculus of variations. 

Jacob Bernoulli 
Jacob Bernoulli 1654  1705 Swiss mathematician who contributed to many areas, perhaps most notably to probability; we owe him the law of large numbers. He also made strong contributions to algebra, calculus, and mechanics. 

Gottfried Leibniz 
Gottfried Leibniz 1646  1716 German philosopher, mathematician, and logician; held the aim of collecting all human knowledge. Made many contributions to mathematics, the most celebrated of which is his independent development of calculus. 

Erhard Weigel 
Erhard Weigel 1625 1699 German mathematician, astronomer, and philosopher who believed that the number was the fundamental concept of the universe.
