The History of the Fisher Space Pen

During NASA's early missions, astronauts used pencils. Paul S. Fisher of Fisher Pen Co. developed a ballpoint pen that works in the unique environment of space—without funding from NASA, using an investment of about $1 million from his own funds.

In 1967, NASA approved the pens for the Apollo missions. In February 1969, the Soviet Union also purchased 100 pens and 1,000 refills for the Soyuz spaceflights. American astronauts and Russian cosmonauts continue to use them today.
