Abraham Ibn Ezrá (c. 1089-1167) spent his youth in al-Andalus (in Córdoba, Seville and Lucena) where he trained in Jewish culture in Arab.
In around 1140 he decided to abandon Sefarad to travel around the North of Africa, probably in the company of Yehudá ha-Leví, and Europe. He thus became a wandering wise man, well received for the knowledge he transmitted to the communities he visited: those of Beziers and Narbonne in France, Rome, England etc.
We are unaware whether he returned to Sepharad or whether he died in a European country. Howver, his multifaceted figure has left a deep mark on the whole intellectual life of the Jews of Europe. His biblical comments are some of the most highly appreciated in the Jewish world; his grammars are a common summary of the philological knowledge of Al-Andalus 11th century which it had not been possible to access up to then without knowing Arab and he introduced into the West the mathematical concepts of fractions and decimals.
He died in around 1167 according to some historians in Calahorra. His fame was so extensive that one of the craters on the moon, 42 kilometres in diameter, currently bears his name: Abenezrah.
