William Tell

Wilhelm Tell (in English William Tell) was an archer from the 13th and 14th century who lived in central Switzerland. He once instructed 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". (TV: 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. (AUDIO: The Settling)
