al-Kindi

Abu Yusuf Ya'qub ibn Ishaq al-Kindi (c. 801-873 CE / 185-260H) was the first major Muslim philosopher and is known as 'The Philosopher of the Arabs' (Faylasuf al-Arab). He served at the Abbasid court in Baghdad and was prolific across philosophy, mathematics, astronomy, medicine, music theory, and cryptography. He was among the first to attempt a synthesis of Greek philosophy with Islamic thought, but took a more theologically conservative approach than later philosophers. He wrote over 260 works, most of which are lost; surviving works include On First Philosophy and treatises on music theory where he extended Aristotelian physics. He was a devout Muslim who believed philosophy and theology were compatible.
