Marie Tharp

After initially studying English and music during her undergraduate years at Ohio University, Marie Tharp turned to the sciences, earning her master’s degrees in geology and mathematics, and became a #STEM pioneer for women everywhere.

Best known as the oceanographic cartographer that produced the comprehensive map of the world’s ocean floor with Dr. Bruce Heezen, Tharp made the once-mysterious “blank canvas” of the ocean depths real and tangible. “[It was] a fascinating jigsaw puzzle to piece together,” she said in 1999. “It was a once-in-a-lifetime – an once-in-the-history-of-the-world – opportunity for anyone, but especially a woman in the 1940s.”
