Marjorie Lee Browne was a noted mathematics educator. She was one of the first African-American women to receive a doctorate in mathematics.
She was also a great educator:
During her time at North Carolina Central University, Browne taught both undergraduate and graduate courses. Her work as an educator was so adored that she later published four sets of lecture notes for other teachers to follow. Under her direction, her college became home to a prized National Science Foundation Institute for secondary education in the area of mathematics.
