Pièce 17 - Letter, from A. F. Lascelles to Susan Buchan

Sir Alan Frederick "Tommy" Lascelles was a British courtier and civil servant who held several positions in the first half of the twentieth century, culminating in his position as Private Secretary to both King George VI and to Queen Elizabeth II. He wrote the Lascelles Principles in a 1950 letter to the editor of The Times, using the pen-name "Senex". Lascelles was born on 11 April 1887 in the village of Sutton Waldron in Dorset, England, the sixth and youngest child, and only surviving son of Commander Hon Frederick Canning Lascelles and Frederica Maria Liddell, and the grandson of Henry Lascelles, 4th Earl of Harewood. He was thus a cousin of Henry Lascelles, 6th Earl of Harewood, who married Mary, Princess Royal, sister of his employers, Edward VIII and George VI. His mother was the daughter of Sir Adolphus Liddell, son of Thomas Liddell, 1st Baron Ravensworth.
After attending school at Marlborough College, followed by Trinity College, Oxford, Lascelles served in France with the Bedfordshire Yeomanry during the First World War, where he rose to the rank of Captain and was awarded the Military Cross, after which he became the aide-de-camp to his brother-in-law Lord Lloyd, the Governor of Bombay from 1919 to 1920.
