In this series, we take a look at important figures in the history of tech. Grace Hopper was the longest serving member of the Navy when she retired. During her career she pioneered important programming concepts that are still in use today. The work she did on loaders and compilers formed the basis of modern programming. She was a driving factor behind the development of the COBOL programming language. She believed that programming could be made more accessible if it used natural language. She was a lifelong teacher and was committed to opening up the field of computing to fields besides mathematics and engineering. For more information check out the excellent, short doc The Queen of Code and the book Grace Hopper and the Invention of the Information Age. Just for fun, here is Grace on David Letterman explaining how fast nanosecond is.
