Meinhard E. Mayer (b. 1929, Romania – d. 2011, United States) is a Professor Emeritus of Physics and Mathematics at the University of California, Irvine, which he joined in 1966.
He received his Ph.D from the University of Bucharest in 1957, where he taught till 1961.
His research interests range from geometric methods in gauge theory, to the application of wavelets in turbulence. He was an early contributor (1958) to the theory of vector-bosons (W and Z bosons) and electro-weak unification, which later became the Standard model, and an early advocate of the use of fiber bundles in gauge theory.
He is a co-author (with Gerald Jay Sussman and Jack Wisdom) of Structure and Interpretation of Classical Mechanics, MIT Press, Cambridge, MA, 2001 ISBN 0-262-19455-4
