The first human footsteps on the surface of the Moon were taken by Neil Armstrong and Buzz Aldrin on 20th July 1969, during the Apollo 11 mission. The United States and USSR were in a race to reach the Moon, and both had failed to accomplish the mission several times over. The famous Apollo 11 had several predecessors, none of which reached the Moon’s surface. The entire world praised the astronaut that spent almost an entire day on the surface of the Moon and who then brought 47.5 pounds of lunar material back to Earth for studies. None of this, however, would have been possible without Margaret Hamilton, the engineer that wrote the code that took humanity to the Moon. Margaret Hamilton was born on 17th August 1936, in Paoli, Indiana. After graduating from Hancock High School, Margaret began her studies at Earlham College where in 1958, she earned her BA in mathematics. The young and talented woman was forced to suspend her education and work as a high school teacher in order to support her husband who was studying law at Harvard.
