Walter Rudin

Walter Rudin (May 2, 1921 – May 20, 2010) was an Austrian-American mathematician and professor of Mathematics at the University of Wisconsin–Madison.

In addition to his contributions to complex and harmonic analysis, Rudin was known for his mathematical analysis textbooks: ''Principles of Mathematical Analysis'', ''Real and Complex Analysis'', and ''Functional Analysis'' (familiarly known to students as "Baby Rudin", "Papa Rudin", and "Grandpa Rudin")''.'' Rudin wrote ''Principles of Mathematical Analysis'' only two years after obtaining his Ph.D. from Duke University, while he was a C. L. E. Moore Instructor at MIT. ''Principles'', acclaimed for its elegance and clarity, has since become a standard textbook for introductory real analysis courses in the United States.

Rudin's analysis textbooks have also been influential in mathematical education worldwide, having been translated into 13 languages, including Russian, Chinese, and Spanish. Provided by Wikipedia
