On January 9, 1894, George S. Parker received U.S. Patent No. 512319 on a Fountain Pen:

George Safford Parker was a sales agent for the John Holland Gold Pen Company before founding the Parker Pen Company in 1888. He received his first fountain pen related patent in 1889 (U.S. Patent No. 416944). In 1894, Parker received the ‘319 patent on his “Lucky Curve” fountain pen feed, which was designed to draw excess ink back into the pen barrel when the pen was not in use. He patented improvements to the Lucky Curve design (U.S. Patent No. 606,231). Parker’s first successful pen was the Parker Jointless, introduced in 1899, which included the Lucky Curve feed. The Lucky Curve feed was used in various forms until at least 1928.
