**Marguerite Lehr**, was born on October 22, 1898 in Baltimore, Marylande and died on December 14, 1987.

Marguerite studied at a Baltimore public school. The only subject that had difficulty at school was in algebra, however, after scoring low in the first trimester as she herself said, "I could have been docile and learned the rules, so I spent the second trimester with 95." She also commented that as she grew up she "didn't know it was cool for a girl to be a" beast "in math."

Marguerite was the only one in her family to go to college. She attended Goucher College where she specialized in mathematics and was a student of Clara Bacon. Lehr was part of the math club in Goucher and in 1918 introduced a new subject in the club "four-dimensional geometry".

Lehr graduated in Ph.D, receiving his math and physics degree in 1925 with the dissertation "The plane quintic with five cusps". This was published in the American Journal of Mathematics in April 1927, pages 197-214.

Lehr was awarded the President of the European Society M. Carey Thomas of Bryn Mawr in 1920, but postponed her participation in the society until 1923 when, along with the AAUW European Society, she spent the academic years 1923-1924 at the University of Rome, Italy, studying algebraic geometry. While in Rome, Lehr was nominated as a math instructor at Byrn Mawr College, accepting the position upon her return in 1924. She remained at Byrn Mawr for the rest of her professional career, progressing to associate in 1929, to assistant professor in 1935. , for associate professor in 1937, and for math teacher in 1955. She did additional postgraduate work at Johns Hopkins University (1931-32), Poincaire Institute in Paris (1949-50), and University of Princeton (in 1956-57).

During World War II, Lehr taught math at the US Information Office on the professional war training program at Bryn Mawr, and during the war period on the V-12 program she taught over the summer at Swarthmore College. His main interest after 1945 was the probability of theories and their applications, and mathematical education, particularly the use of television in teaching.

"Most people associate math with finding solutions or proving, and it's easy to understand why. Mathematics gives us good rules for quick answers, and gives us good reason to trust those rules. But life shows; as we learn to Asking good questions, the answers come, and increasingly powerful than when we try to find it.These surveys are concerned with raising questions - questions of practical importance or pure curiosity - questions about number, space, model, logic, which have increased. our understanding of the world we live in. "

Marguerite was a great student and an inspiring teacher, remembered as the best in classical education, but not afraid to explore and use new ideas and methods, she made remarkable contributions to education not only by helping others understand the nature of mathematics and its role in modern world, but also for demonstrating and explaining the discipline of knowledge and its indispensable value.

Marguerite Lehr received the Christine R. and Mary F. Lindback Prize "recognizing her as a brilliant teacher who will be remembered by generations of students." She has been a member of the American Mathematical Society, the Mathematical Society of America, the Institute of Mathematical Statistics, and the Biometric Society, and has served on the International University of Women's Federation award committees and the Woodrow Wilson National Foundation. In an interview with Pat Kenshaft, Lehr commented that "the most valuable experience of her life was the eight years she spent interviewing candidates for the Woodrow Wilson undergraduate society."
