The following post is excerpted from Design Decoded.
The Fisher Space Pen was created by inventor, pen manufacturer, and (brief) JFK political opponent Paul C. Fisher. Fisher had been an innovator in the pen industry for years, even before he started his own company. His mastery of the ballpoint pen can be attributed in part to his experience working with ball bearings in a airplane propeller factory during World War II. Fisher also invented the “universal refill” ink cartridge, ultimately leading him to create the very first “Anti-Gravity” pen, the AG7, which was patented in 1966 and famously used by astronauts during the Apollo space missions. However, it’s a popular misconception that NASA invested millions of dollars into the development of the zero-gravity writing instrument. They didn’t. Nor did the space agency approach Fisher to develop a pen for use by American astronauts. According to a 2006 piece in Scientific American, the truth is that Fisher had been working on the design for years and had invested $1 million into the pen’s development. But Fisher wasn’t dreaming of astronauts writing postcards from Earth orbit, he was just looking to make a good pen that worked without leaking. After years of research and prototypes, he created what he believed to be the perfect pen – a pen with ink that wasn’t exposed to air and didn’t rely on gravity so it wouldn’t leak or dry up; a pen that could write underwater and function at temperatures ranging from -30 to 250 degrees Fahrenheit. Fisher’s breakthrough was perfectly timed with the space race and he offered the pens to NASA for consideration. After two years of testing, it was approved and Fisher’s pen accompanied Apollo 7 astronauts into space.
