W. G. Grace
From Tardis Wiki, the free Doctor Who reference
W.G. Grace was a famous cricketer in the early 20th century. Sir Robert Muir compared the Fifth Doctor to him after a cricket game at Cranleigh Hall. Sir Robert referred to him as the Master, which momentarily confused the Doctor as he believed that he was talking about his enemy with the same name. (DW: Black Orchid)
