Thomas Becket was the archbishop of Canterbury.  He was at odds with the king for trying to remove the church from royal jurisdiction, and was eventually murdered by four knights in Canterbury Cathedral.

Thomas Becket is typically dressed in his boshop's robe (as can be seen here), and sometimes carries a crosier.  He often also hold the palm branch of martyrdom.
