In the world of computing, one name that stands out is Katherine Johnson. Her extraordinary contributions to NASA’s space program have been well-documented, and the movie “Hidden Figures” brought her story to a wider audience. But few people know about another computer called Katherine, which played a crucial role in a significant moment in American history.
In the early 1960s, the United States was embroiled in the Cold War, and President John F. Kennedy had set his sights on putting a man on the moon. NASA was at the forefront of this endeavor, but there was a significant challenge that had to be overcome: the mathematical calculations necessary to determine the trajectory of the spacecraft were prohibitively complicated, and there was no computer powerful enough to perform them.
Enter Katherine, the computer. This was not a machine, but a group of mathematicians led by Katherine Strickland. Katherine had been hired by the National Advisory Committee for Aeronautics (NACA), which was the predecessor to NASA, and she had quickly proven her worth. She and her team had developed mathematical models that accurately predicted the behavior of airflows around aircraft, which was crucial for designing more efficient and effective flying machines.
When NASA realized that they needed help with their moonshot calculations, they turned to Katherine and her team. The timing was perfect. NASA had just acquired a powerful IBM mainframe computer, but it was still in the process of being programmed. In the meantime, Katherine and her colleagues performed the calculations manually, using slide rules and pencil and paper.
Their work was meticulous and precise, and it proved to be essential. In February 1962, John Glenn became the first American to orbit the Earth, and Katherine’s calculations had helped ensure that his spacecraft stayed on course. It was a significant triumph, not just for NASA, but for all of America. The space race had taken on a new level of urgency, and Katherine and her team would continue to play a crucial role in it.
The story of “A Computer Called Katherine” has largely been overlooked, but it is a reminder of the incredible contributions of so many unsung heroes in our history. Katherine Strickland and her team were trailblazers who broke down barriers and helped pave the way for future generations. Their work was meticulous, their dedication unwavering and their impact immeasurable. We owe them a debt of gratitude.
