Two Englishmen, Henry Martin and Frederick Miles supported this idea. They then took part in the manufacture of this new stationery and were sold to the British Air Force requiring a leak-proof and overflowing stationery for use on aircraft used in World War II.
At the same time, in the United States, Milton Reynolds from Chicago purchased the new stationery. He then refined it and sold it to American soldiers. But the pen is not nearly as perfect as a ballpoint pen at the moment.
Franz Szech, a California resident, tried to find the perfect ink and managed to make the ink from his home kitchen. The ink was much more durable and durable in his pen, but unfortunately the ink gradually became dry when exposed to air.
After World War II was over, people gathered in the Gimbels storefront storefront in New York. In the storefront is provided a large water tank surrounded by visitors. This water tank is used to demonstrate the stationery of a pen used underwater. The pen was promoted using Szech's ink.
Before using a special ballpoint pen, the astronauts use ordinary carbon pencils because ordinary ballpoint pens will not be used due to the vacuum pressure in space that will suck up the ink.
The space-specific ballpoint pen designed by Paul C. Fisher, in July 1966. The pen test included underwater conditions, weightless space and vacuous pressure. The pen was first tested by Dr. Robert Gilruth, Director of NASA, in Houston, Texas. In 1967, the ballpoint pen passed the test and was chosen for use by Apollo astronauts
