Al-Samawal al-Maghribi

Al-Samawʾal ibn Yaḥyā al-Maghribī (Arabic: السموأل بن يحيى المغربي, c. 1130 – c. 1180), commonly known as Samawʾal al-Maghribi, was a mathematician, astronomer and physician.

[2] His father was a rabbi from North Africa named Yehuda ibn Abūn.

[3][4] Al-Samaw'al wrote the mathematical treatise al-Bahir fi'l-jabr, meaning "The brilliant in algebra", at the age of nineteen.

[5] He also wrote a famous polemic book in Arabic debating Judaism known as Ifḥām al-Yahūd (Confutation of the Jews).

A Latin tract translated from Arabic and later translated into many Western languages, titled Epistola Samuelis Marrocani ad R. Isaacum contra errores Judaeorum, claims to be authored by a certain R. Samuel of Fez "about the year 1072" and is erroneously connected with him.
