David B. Mumford

From the American Mathematical Society:

"David Mumford is one of the most influential algebraic geometers of the second half of the twentieth century… He made seminal contributions to many different aspects of the subject, such as the theory of surfaces and more general questions of classification, the theory of singularities of algebraic varieties, and moduli problems. Mumford is the founder of geometric invariant theory, which provides a framework for treating moduli spaces in many different contexts. Some years ago he left algebraic geometry to pursue other interests and has contributed to such varied fields as brain science, computer vision, neurobiology, cognitive science, and the biology and psychology of perception."
