who invented fountain pen and in which year
Fountain pen Progress in developing a reliable pen was slow until the mid-19th century because of an imperfect understanding of the role that air pressure plays in the operation of pens. Furthermore, most inks were highly corrosive and full of sedimentary inclusions. The Romanian inventor Petrache Poenaru received a French patent on May 25, 1827, for the invention of the first fountain pen with a barrel made from a large swan quill.[8]
