I read Soundings by Hali Felt and learned that Marie Tharp and Bruce Heezen (scientist and co-worker and partner in every sense of the word with Marie) literally mapped the ocean floor. I had never heard of either one of them before this. Had no idea that Maria took the soundings gathered by Heezen and others at the Lamont-Doherty Earth Observatory and drew the map - drew the map!!! - of the ocean floor.
She was a cartographer of the ocean floor.
There is so much about Marie's career that blows my mind (here's a good overview in her obituary from Columbia University), but a couple of things stand out. First, is that she took data that had been sitting around for years and said "why don't we actually create a map from it?" (Basically.) And second that she looked at those maps and realized they were proving continental drift with the maps. Now, it seems obvious but then - the 1950s - it was heresy. (Even Heezen fought her initially.) But Marie hung in there and let the maps speak for themselves. Her work was irrefutable and could not be denied (though plenty of folks denied it for way too long.) She proved what poor Alfred Wegener had asserted in 1912 and she changed the field of oceanography.
I bet you have never heard of Marie Tharp though.
Hali Felt has a great blog post about Marie and what she would have thought about her work largely being undiscovered during her lifetime (and the struggle of her professional life).
It makes me both sad and happy that the record has finally be set straight. Marie is not here to enjoy Soundings; she doesn't know she has been discovered. There are likely so many other stories like hers out there, lost and waiting to be found by a curious reader. We fill our heads with so much that doesn't matter; and we forget people like Marie who really did change the world.
