Adrian Willaert
In July 1515, Willaert worked for the Cardinal Ippolito I d'Este of Ferrara.  Ippolito liked to travel, and he often took Willaert and other musicians with him to places such as Hungary, where he probably spent two years, from 1517 to 1519.  When Ippolito died in 1520, Willaert worked for Duke Alfonso d'Este of Ferrara.  In 1522 Willaert had a job at the court chapel of Duke Alfonso; he stayed there until 1525.
