I have never heard about Grace Hopper until recently. After watching this short documentary from FiveThirtyEight, I can't believe it took me so long to know her story.
Grace Hopper was a computing pioneer in a male-dominated field. She has also invented the world's first compiler.
In my lay terms Compilers are what enables computers to understand humans when we code in programming languages (e.g. Python, R, Java, etc). This is something we may take for granted today, but she is the person who conceived this idea, which made possible the rapid spread of personal computers.
This documentary is an important piece of the history of computing and a truly inspirational story, specially for women interested in coding and computer science.

ps. Grace has also been credited to have coined the term "computer bug" after finding a moth stuck inside Harvard's Mark II computer in 1947, hence the term "debug" for solving problems in computer code.
