William of Ockham or Occam was an English Franciscan friar, scholastic philosopher, apologist, and Catholic theologian, who is believed to have been born in Ockham, a small village in Surrey. He is considered to be one of the major figures of medieval thought and was at the centre of the major intellectual and political controversies of the 14th century. He is commonly known for Occam's razor, the methodological principle that bears his name, and also produced significant works on logic, physics and theology. William is remembered in the Church of England with a commemoration on the 10th of April.

The Franciscans are a group of related mendicant religious orders of the Catholic Church. Founded in 1209 by the Italian saint Francis of Assisi, these orders include three independent orders for men, orders for nuns such as the Order of Saint Clare, and the Third Order of Saint Francis open to male and female members. They adhere to the teachings and spiritual disciplines of the founder and of his main associates and followers, such as Clare of Assisi, Anthony of Padua, and Elizabeth of Hungary. Several smaller Protestant Franciscan orders or other groups have been established since late 1800's as well, particularly in the Anglican and Lutheran traditions.
