RDML Grace Brewster Murray Hopper PhD

Interesting that she joined the navy reserves at 36 years old as a PhD. and eventually made O-7 (which means she was a very high ranking officer.) Could it be possible that her work with computers had absolutely nothing to do with her service in the navy?

All anyone knows about former rear admiral Grace Hooper is that she was a woman, she was a rear admiral, and she "invented the first compiler." Nobody ever talks about the details
