Raphael
His mother Màgia died in 1491 when Raphael was eight, followed on August 1, 1494 by his father, who had already remarried. Raphael was thus orphaned at eleven; his formal guardian became his only paternal uncle Bartolomeo, a priest, who subsequently engaged in litigation with his stepmother. He probably continued to live with his stepmother when not staying as an apprentice with a master. He had already shown talent, according to Vasari, who says that Raphael had been "a great help to his father". A self-portrait drawing from his teenage years shows his precocity. His father's workshop continued and, probably together with his stepmother, Raphael evidently played a part in managing it from a very early age. In Urbino, he came into contact with the works of Paolo Uccello, previously the court painter (d. 1475), and Luca Signorelli, who until 1498 was based in nearby Città di Castello.
Raphael Levi Hannover
Raphael Levi Hannover (1685 – May 17, 1779) was a German mathematician and astronomer. The son of Jacob Joseph, Hannover was born at Weikersheim, Franconia in 1685. He was educated at the Jewish school of Hanover and at the yeshivah of Frankfurt am Main, and became bookkeeper in the firm of Simon Wolf Oppenheimer in Hanover. Here he attracted the attention of Leibniz, and for a number of years was one of his most distinguished pupils (including last secretary), and afterward teacher of mathematics, astronomy, and natural philosophy. He also corresponded with Moses Mendelssohn.
