The Marjorie Lee Browne Colloquium was established in 1999 in the Department of Mathematics, in observance of Martin Luther King day. Every year this colloquium brings a distinguished speaker to campus to present a talk that highlights their research while also addressing the issue of diversity in the sciences. The speakers have included leaders in the DEI initiative within Mathematics, including several alumni of UM. The colloquium honors Marjorie Lee Browne, who received her Ph.D. in 1950. She was the third black woman to receive a Ph.D. in Mathematics, and the very first to receive a Ph.D. in this field from the University of Michigan.
