Astronomer mathematician physician
Ahmad ibn Yusuf was born in Baghdad and moved with his father to Damascus in 839.
He later moved to Cairo, but the exact date is unknown: since he was also known as al-Misri, which means the Egyptian, this probably happened at an early age. Eventually, he also died in Cairo.
He probably grew up in a strongly intellectual environment: his father worked on Mathematics, Astronomy and Medicine, produced astronomical tables and was a member of a group of scholars.
