Pierre I accompanied Étienne to Vienna in 1569 and there produced several portraits of him. Pierre was forced to enter Catherine de Medici shortly after Étienne, but his name only figures for the first time in the records of her court in 1583. Unlike his brother, he was not taken on by Henry IV of France, since in his will he always refers to himself as "painter and 'valet de feue' to the Queen Mother". He was then living in Paris on rue du Temple and left no issue.
