Birgit Speh (born 1949)[1] is a professor of mathematics at Cornell University.[2] She is known for her work in Lie groups, including Speh representations (also known as Speh's representations).[3]


Speh received her Ph.D. from Massachusetts Institute of Technology in 1977.[4] She was the first female mathematician to be hired by Cornell University.[5]

Awards and honors

In 2012, Speh became a fellow of the American Mathematical Society.[6]
