As William Berruyer (French: Guillaume Berruyer), he was a descendant of the family of the ancient Counts of Nevers.
He was educated under the care of Peter, Archdeacon of Soissons, his maternal uncle.
At an early age he learned to eschew the vanities of the world and to give himself with ardor to exercises of piety and to the acquisition of knowledge. Upon entering the ecclesiastical state he became a canon of Soissons and of Paris. Later he resolved to abandon the world and enter the Order of Grandmont.
He lived in this order for a period of time and practiced great austerities.
He took the habit at Pontigny, and after some time became abbot, first of Fontaine-Jean near Sens, and later of Chaalis near Senlis. He had a special devotion to the Blessed Sacrament and loved to spend much of his time at the foot of the altar.
In the year 1200, the clergy of the Church of Bourges elected him to succeed Henry de Sully, their archbishop. The news quite overwhelmed him with grief.
In his new office of archbishop, he continued his austerities, to the point of constantly wearing a hair shirt and never eating meat.
He was instrumental in the ongoing construction of the Gothic Cathedral of Saint Stephen, begun under his predecessor, Henry de Sully, in 1195. In the early part of his ecclesiastical reign, the lower half of the cathedral was completed and by December 1208, the choir was partially finished, at which time he was able to celebrate the Christmas liturgy. In his last will and testament he requested to be buried with his hair shirt and in ashes.
His feast day is commemorated on January 10.
Witnesses claimed that he performed eighteen miracles during his saintly life and that he performed another eighteen miracles after his death. Saint William was canonized on May 17, 1218, by Pope Honorius III. He is a patron saint of the University of Paris.
