Abu 'Ubayd al-Juzjani

Abu 'Ubayd al-Juzjani (died 1070) was a Muslim physician and chronicler from Guzgan, which the source places in modern Uzbekistan. He was a pupil of Avicenna, whom he first met in Gorgan, and he spent many years with his master in Isfahan, where he became his lifetime companion. After Avicenna's death he completed Avicenna's autobiography with a concluding section. The historian Ibn Abi Usaibia describes the two men living together in the residence of the Sheikh al-Raiss, the title given to Avicenna, and spending each night studying one of the instructions of the Canon and the Shifa. The source gives no birth date, so this entry records only his death year, his teacher, his companionship with Avicenna and his completion of the autobiography.
