Dennis Raoul Whitehall Silk CBE (8 October 1931 – 19 June 2019[1]) was an English first-class cricketer and a public school headmaster, latterly as Warden of Radley College (1968—1991).

He went on to play first-class cricket for Somerset as an amateur during the school summer holidays, but gave priority to his teaching career.

[12] Oliver Popplewell wrote that his sons Nigel and Andrew "thrived" at Radley under Silk.

[14] During the early 1950s, Silk was introduced to the cricket-loving poet Siegfried Sassoon by a mutual acquaintance, Edmund Blunden.

[16] The cricket writer David Foot likened Silk to Sassoon, describing him as "a gentle, rounded, civilised man, a scholar without ostentation, literate, a lover of poetry and someone with a similar sense of quiet fun".

[17] Dennis Silk sat for the sculptor and former Radley College pupil Alan Thornhill, for a portrait in clay.

[18] The correspondence file relating to the Silk portrait bust is held as part of the Thornhill Papers (2006:56) in the archive of the Henry Moore Foundation's Henry Moore Institute in Leeds, while the terracotta remains in the collection of the artist.

[20] Dennis Silk's death was marked by a Service of Thanksgiving held in Southwark Cathedral; 1,200 people attended, with representatives from Radley, Marlborough and the MCC.
