The Space Pen (also known as the Zero Gravity Pen), marketed by Fisher Space Pen Company, is a pen that uses pressurized ink cartridges and is able to write in zero gravity, underwater, over wet and greasy paper, at any angle, and in a very wide range of temperatures.
The Fisher Space Pen was invented by American industrialist and pen manufacturer Paul C. Fisher and is manufactured in Boulder City, Nevada, United States of America. Paul C. Fisher first patented the AG7 "anti gravity" pen in 1965. Pens claiming some or all of the same abilities have also appeared on the market from other manufacturers.
Paul Fisher developed the Fisher Space Pen almost 40 years ago during a time when the 'race for space' was being fought. When astronauts began to fly they used ordinary pencils. The lead of these pencils could easily brake off causing dangerous situations when they floated around in the gravity-less space cabin. A safer and more reliable writing instrument was needed, the Fisher Space Pen. More than one million dollars went into the development of the Fisher Space Pen and in 1965 Paul Fisher successfully developed the first pressurized Fisher Space Pens.
