[email protected] Abstract. Alfred Rosenblatt (1880–1947) was a Polish mathematician born into a Jewish fam- ily in Krakow (Kraków, Poland). He studied in Vienna, Krakow, Göttingen, and worked at the Jagiellonian University in Krakow (1910–1936) and at the University of San Marcos in Lima, Peru (1936–1947). During the Second World War, Rosenblatt accepted Peruvian citizenship. His work was important for the development of mathematics in Peru, including the foundation of the National Academy of Exact Sciences, Physics and Natural Sciences in Lima. He is mentioned among the four mathematicians of the twentieth century most important for Peru (F. Villar- real, G. García Diaz, A. Rosenblatt and J. Tola Pasquel). He spent the first half of 1947 on a scholarship at the Institute for Advanced Study in Princeton and had several lectures at other universities in the USA. Rosenblatt published almost three hundred scientific papers in various fields of pure and ap- plied mathematics, including ordinary and partial differential equations, algebraic geometry, the- ory of analytic functions, probability, mathematical physics, three-body problem, hydrodynamics 2010 Mathematics Subject Classification: Primary: 01A60, 01A70, 01A90, Secondary: 14-03, 30-03, 34-03, 40-03, 60-03, 76-03.
