       <p>In 1960 Margaret Hamilton got a job as a programmer at the MIT Instrumentation Lab to support her husband during his three-year study at Harvard Law. She originally planned to attend graduate school for mathematics after her husband finished school. However, Hamilton decided to stay in the lab and develop software for the Apollo space program. Hamilton was very successful as a programmer. Hamilton and her colleagues were the pioneers of systems programming and invented many core ideas in computer programming. </p>
        <p>
In 1965 Hamilton was put in charge of developing the onboard flight software on the Apollo computers. Programming was much different during the time that Hamilton was working with the Apollo space program. The software was made with punch card programming (<a href="https://www.youtube.com/watch?v=KG2M4ttzBnY" target="_blank"> more information about punch card programming</a>). This process was tedious and much slower than current processes. </p>
        <p>
On July 20th, 1969 there was an error on the Apollo computer just minutes before Apollo 11 touched down on the Sea of Tranquility. The computer was outputting many error messages during the landing because it was being overwhelmed doing a series of unnecessary calculations. During this moment, the technical arguments made by Hamilton and others saved the day. Before the Apollo 11 mission Hamilton added a code that would prevent a crash by making focusing on the highest priority job after her daughter had crashed a simulation by pressing a key. Thanks to the work done by Hamilton and her colleagues, the Apollo 11 mission was a success.
