The precise date of Robert Campin's birth is unknown, but a document of 1422 gives his age as forty-seven, making his birthdate c. 1375. He was active in Tournai (now in Belgium) by 1406. He purchased citizenship there in 1410, which has been taken as an indication that he was born elsewhere, though this need not be the case. He evidently enjoyed a prosperous career, receiving a number of civic commissions and taking on several apprentices. He must also have had some court contacts, as the countess of Hainaut interceded on his behalf after he had been sentenced for immoral behavior in 1432. He died in 1444.
