Marie Tharp was a geologist and oceanographic cartographer. Her maps of the ocean floor, created with data provided by Bruce Heezen, introduced the world to the Mid-Atlantic Ridge and led to a paradigm shift within the geological scientific community: the acceptance of plate tectonics and continental drift.
Marie Tharp was born July 30, 1920, in Ypsilanti, Michigan. When she was still a young girl, she followed her father, a soil surveyor for the United States Department of Agriculture, into the field. However, she also loved to read and wanted to study literature at St. John’s College in Annapolis, but at the time women were not admitted there. So she went to Ohio University, where she graduated in 1943.
