Gianfrancesco Penni
Born in Florence to a family of weavers, Penni entered Raphael's workshop very early in his life, and collaborated with him on several works, including the famous Rooms of the Vatican Palace, as well as the frescoes of Villa Farnesina, both in Rome. Heinrich Wölfflin and some other writers credited him with the entire execution of the Raphael Cartoons, with Raphael only creating the initial design, though more recent writers believe Raphael did much of the work himself.
Joseph Raphael
Before long he adopted a style borrowed from French Impressionism, eventually using broader, freer, more Post-Impressionist brushstrokes. By 1912 he was married and living in Uccle, Belgium, a suburb of Brussels. He produced many paintings of the countryside near his home. As Raphael's international reputation grew, his family grew as well, to include four daughters and a son. His family frequently appeared in his figurative works. By the early 1930s Raphael and his family were living in a suburb of Leiden, Holland, and he painted often in nearby Bruges. In 1939, with World War II approaching, he returned to San Francisco, where he lived and maintained a studio on Sutter Street until his death on December 11, 1950.
