"I'm sorry, but you have fallen prey to a common myth."The fountain pen dates back to 1827; it was invented by the Romanian Petrache Poenaru, who received a French patent for a pen with a replaceable ink cartridge..."Petrache Poenaru did not invent the fountain pen. As stated in French patent, No. 3208, issued to him on May 23, 1827, he patented an IMPROVEMENT on existing designs. And his pen did NOT have a replaceable ink cartridge. People who think it did have misunderstood his patent."
