who invented the world's first fountain pen
Fountain pen An early historical mention of what appears to be a reservoir pen dates back to the 10th century. According to Al-Qadi al-Nu'man (d. 974) in his Kitab al-Majalis wa 'l-musayarat, the Fatimid caliph Al-Mu'izz li-Din Allah demanded a pen that would not stain his hands or clothes, and was provided with a pen that held ink in a reservoir, allowing it to be held upside-down without leaking.[2]
