Frederick Luke Val Fildes (13 June 1879 – 22 April 1970) was a British fencer, solicitor and company secretary.
He served with the Coldstream Guards but after being wounded on the Somme he became superintendent of physical and bayonet training at the Aldershot Command.
After the war he went into business rather than return to the Bar and became secretary of Lever Brothers Limited.
It is based partly on his father's correspondence and the diary of his maternal uncle Henry Woods R.A., who lived and painted in Venice.
Luke Val married Goscombe John's daughter Muriel eighteen months later in 1915.
