Biography

Abraham bar Hiyya was a Spanish Jewish mathematician and astronomer.

Jewish philosophy - Wikipedia

In the Hebrew of his time 'Ha-Nasi' meant 'the leader' but he is also known by the Latin name Savasorda which comes from his 'job description' showing that he held an official position in the administration in Barcelona.

Abraham bar Hiyya is famed for his book Hibbur ha-Meshihah ve-ha-Tishboret(Treatise on Measurement and Calculation), translated into Latin by Plato of Tivoli as Liber embadorum in 1145.

This book is the earliest Arab algebra written in Europe. It contains the complete solution of the general quadratic and is the first text in Europe to give such a solution. Rather strangely, however, 1145 was also the year that al-Khwarizmi's algebra book was translated by Robert of Chester so Abraham bar Hiyya's work was rapidly joined by a second text giving the complete solution to the general quadratic equation.
