Katherine Johnson

Katherine JohnsonWikipedia.orgKatherine Johnson, born on August 26th, 1918 in Virginia, America, is an African-American mathematician who played a big role in the first space flights during her 35-year career at N.A.S.A. She was the genius who made the complex manual calculations and helped the space agency pioneers to use computers to perform the task in a racist and sexist country at that time. Her work included calculating trajectories launch windows and emergency return paths for project Mercury space flights. She is considered as a hero and a pioneer for space science and computing. For all those reasons and her total application in science, she received many awards and the Presidential Medal of Freedom. She is my hero because her determination and her courage for science always gives me strength when I want to give up, because it makes me realize that just because you are a woman doesn't mean you can’t change the world in science, and that the key of the success is hardwork and courage.
