Col. Radcliffe Thornberry, R.A.F., (Ret.) is the father of Nigel. Listening to him, it is easy to hear where his son Nigel got his trademark voice, as well as his sense of adventure. Radcliffe lives along with his wife Cordelia at Thornberry Manor in Scotland. A former member of the Royal Air Force, he enjoys hang gliding, playing the bagpipes, and loves a good adventure.
Many of Nigel's more admirable qualities can be traced back to his father, who helped his son nurse sick animals back to health when Nigel was just a little boy. Although he and Cordelia seem very different, he loves his wife tremendously but isn't afraid to go on a perilous adventure against her wishes. Both he and Nigel are voiced Tim Curry, which explains why Nigel's and Radcliffe's voices are the same.
