WALTER KURT HAYMAN
Extract from the citation: Professor Hayman is awarded the De Morgan Medal for his contributions to complex analysis and potential theory. Following the tradition established by Hardy and Littlewood, he became the undisputed leading international authority in classical complex analysis, through work contained in more than one hundred research papers and several monographs. His natural creative talent for solving problems led in particular to very deep results in the theory of functions on the unit disc, integral and schlicht functions, and subharmonic functions in several variables. Few have been as dedicated to their chosen area of mathematics as Walter Hayman, or promoted it in the world in such a dedicated fashion.
