William Tell

William Tell was an archer from Switzerland who once instructed an unknown incarnation of the Doctor in archery. After successfully using a Sevateem crossbow to sever a length of rope, the Fourth Doctor credited the Swiss for his skill, and added that Tell was a "charming man". (DW: The Face of Evil)

The Seventh Doctor once told his companion Ace that he had met Tell, though she believed that he may have been joking. (BFA: The Settling)
