Writing was once linked to an inkwell, a quill or a dip pen. Writers had to stop often to collect ink before continuing. This created problems for people who had to write long texts or take notes during lessons. In 1827, Petrache Poenaru developed a pen that stored ink inside its barrel. He was studying in Paris at the time. The French Government granted him a patent on May 25, 1827. The invention is regarded as the world's first patented fountain pen. It used a swan quill as an ink reservoir and allowed ink to reach the nib without repeated dipping. The invention became part of the history of writing instruments and later influenced the development of fountain pens.
