Today (November 21, 2022) Google Doodle is honoring Marie Tharp.
Marie was a renowned US geologist and oceanographic cartographer. On November 21, 1998, the Library Of Congress named her one of the greatest cartographers of the 20th century.
Marie was born in Ypsilanti, Michigan, in 1920. Her father, who worked in the Department of Agriculture, introduced her to map-making.
She attended the University of Michigan and gained her Master’s degree in petroleum geology.
At the observatory, Marie spent her time creating maps of the ocean floor based on data provided by geologist Bruce Heezen.
Through research, Tharp discovered the Mid-Atlantic Ridge. However, her findings were disregarded as “girl talk” by Heezen at the time.
“I was so busy making maps, I let them argue. I figured I’d show them a picture of where the rift valley was and where it pulled apart. There’s truth in the old cliché that a picture is worth a thousand words and that seeing is believing.”
“I had a blank canvas to fill with extraordinary possibilities, a fascinating jigsaw puzzle to piece together. It was a once-in-a-lifetime – a once-in-the-history-of-the-world – opportunity for anyone, but especially for a woman in the 1940s.”
