Sir Henry Felix Clay, 6th Baronet (8 February 1909 – 8 June 1985), was an English engineer.
Clay was educated at Gresham's School, Holt, and Trinity College, Cambridge, graduating MA in 1935.
[2][3] The Clay family lived at number 18, Kensington Park Gardens, Notting Hill, London.
When Clay was thirteen, his first cousin once removed, Richard Meinertzhagen, came to live in the house next door, number 17.
Meinertzhagen was a well-known ornithologist and a distinguished soldier, but he was also a "colossal fraud", who stole bird specimens and described spurious species and who invented and exaggerated his military adventures.
