1905 – 1977
Rózsa Péter was a Hungarian mathematician and logician, widely regarded as the founding mother of recursive function theory. She made foundational contributions to the study of primitive recursive functions, demonstrating their limitations and developing the theory systematically. Her 1951 book 'Rekursive Funktionen' was the first monograph dedicated entirely to recursion theory.
Authored the first book dedicated to recursive function theory (Rekursive Funktionen, 1951)
Proved key results on the limitations of primitive recursive functions, including non-primitive-recursive computable functions
Pioneered the systematic study of primitive recursive functions as an independent field
Awarded the Kossuth Prize, Hungary's highest state award for scientific achievement
Advocated for mathematics education and wrote 'Playing with Infinity' for general audiences
