St George's Preparatory School was a school located in Ascot.
In his youth, Winston Churchill attended the school. He was not fond of or good at learning Latin, and because of this, he was assigned a special tutor that lived in a cubby. Churchill found the new teacher strange, but at the same time very wise and good for conversation. On one occasion, Churchill asked why "Mensa" meant both "table" and "O table". The figure frowned and responded that one could use the latter to address a table. Churchill was highly amused by this.
On the morning of 18 March 1882, Churchill was sad to learn that the teacher had disappeared with no sign of where he had gone. (PROSE: The Lost Diaries of Winston Spencer Churchill)
