One of the greatest scientific reseachers of genetic field, she was Nobel Prize of Medicine in 1983, even thought it wasn't easy as a woman reseacher. Her innovating results came from the corn and her searching of the human genome. McClintok watched the "letters" that composed her DNA and saw, for the first time, that exists a serie of  genetic sequences which could change its position. So, she produced the first genetic map of the corn, that later it was used to demonstrate the working of the process and the genetic regulation.

She was born to a very humble family in Virginia and her destiny as a black woman seemed decided (The racial segregation laws only let her to be teacher). But Katherine soon start to stand out for her control of the numbers and the mathematics: her intelect let her to graduate in Maths and French at the young age of 18. She worked as a teacher during years and in 1953 she started to work at Calcule department of the NACA (former NASA), where she made all the operations that the aeronautic engineers needed. Her curiosity and numerical control led to calculate everything from Mercury project, becoming the responsible of the  parabolic trajector y of the first manned flight into space . She also calculated the traject of Apollo 11 which sent the first men to the Moon and was the key of the return of Apollo 13.

Lovelance was the first person to develop a cumputering code and ahead of her time. She discovered that, through a serie of mathematical symbols and rules, large serie of numbers could be calculated,  bring forward in that way the capacities that later on machines adquired. Her mother was a  political activist mathematic and her father was George Byron poet, thanks to her social position she met important scientists, what caused her educational development.
