Josquin des Prez
We know that he became a singer in the chapel of Aix-en-Provence, the chapel of the Duke of Anjou. After the duke's death in 1480 he worked for King Louis XI of France until he, too, died in 1483. We do not know where he worked after that, but he had some music published, including six chansons. He probably worked for some time in Milan.
