Born 980 CE, died 1070 CE.
Abū 'Ubayd al-Jūzjānī (d.1070) (ابو عبيد جوزجانی) was a Muslim physician and chronicler from Guzgan (modern day Uzbekistan). He was the famous pupil of Avicenna, whom he first met in Gorgan. He spent many years with his master in Isfahan, becoming his lifetime companion. After Avicenna's death, he completed Avicenna's Autobiography with a concluding section. The historian Ibn Abi Usaibia refers Avicenna and his close companion Abu Ubayd lived together the residence of Sheikh al-Raiss (which is the title given to Avicenna) and were used to pass each night on studying one by one the Canon and Shifā's instructions.
