“the guy” who invented the space pens is a whole entire company that makes many things and is staffed by many people.
The “space pens” are just their normal pens but with pressurized ink cartridges and special ink (and the development was paid in full by Fisher) but they were bought at MSRP by NASA. And because everything NASA does is public domain, you can actually see the original PO for the pens! They spent $2.25/pen in November 1967 which would be worth about $28 today.
