Spanish-born Sephardi Jewish astronomer, astrologer, mathematician, rabbi and historian who served as Royal Astronomer in the 15th century to King João II of Portugal. The crater Zagut on the Moon is named after him.
Zacuto developed a new type of astrolabe, specialized for practical determination of latitude while at sea, in contrast to earlier multipurpose devices intended for use ashore.
Abraham Zacuto's principal claim to fame is the great astronomical treatise, written while he was in Salamanca, in Hebrew, with the title Ha-ḥibbur ("The Great Book"), begun around 1470 and completed in 1478.
In 1504, while in Tunisia, Abraham Zacuto wrote a history of the Jewish people, Sefer yuḥasin, since the Creation of the World until 1500, and several other astronomical/astrological treatises.
He died in Damascus, probably in 1515.

Cantera Burgos, The Jewish Quarterly Review, New Series, Vol. 24, No. 1 (July 1933), p. 87: "PROFESSOR F. Cantera Burgos ... suggests that Zacuto was born not about 1450, as is usually stated, but at three o'clock in the afternoon of August 12, 1452."
