Mrs. Maria do Pilar Ribeiro passed away March 28, 2011. She was the widow of Professor Hugo Ribeiro, who was a member of the faculty of the Math. Dept. at Penn Sate from 1961 to 1976. Pilar also served as an instructor in the PSU Math Dept.
Pilar would turn 100 years old on October 5, 2011. She was one of the founders of the Portuguese Mathematical Society, in 1941, holding the member number 1. She was also a co-founder of the Mathematics popularization journal "Gazeta de Matemática", which is still published. Together with her husband and a few others, she was a member of a very dynamic generation that during the war tried to develop Mathematics in Portugal, against the establishment and political persecution. They were all eventually chased by the dictatorial regime that then dominated the country, which was very suspicious of any kind of free thinking. This led the Ribeiro's to the United States in the late 1940's, and eventually to Penn State, a place which they loved very much.
