Which of these events occurred FIRST: the computer chip was patented, the Berlin Wall was erected, the birth control pill was OK'd by the US Food and Drug Administration

The computer chip was patented first among the three events listed, with Jack Kilby filing his patent application for the integrated circuit on February 6, 1959. This groundbreaking invention, also independently conceived by Robert Noyce, revolutionized electronics by integrating multiple transistors and other components onto a single semiconductor material. It laid the foundation (Review) for virtually all modern electronic devices, from computers to smartphones, making them smaller, faster, and more affordable.

Just over a year later, on May 9, 1960, the U.S. Food and Drug Administration (FDA) approved the birth control pill, Enovid, for contraceptive use. This approval marked a significant moment in reproductive health and women's rights, offering women unprecedented control over their fertility. The pill quickly gained widespread use, profoundly influencing societal norms and individual freedoms in the decades that followed.

The last of these pivotal events occurred on August 12–13, 1961, when the Berlin (Review) Wall was erected. Constructed by East Germany, this barrier physically divided East and West Berlin, becoming a potent symbol of the Cold War's ideological and political divisions. Its purpose was to prevent the mass exodus of East Germans to the West, and it stood for nearly three decades before its fall in 1989.
