Task: Question Answering
Input (English): Passage: On the night of his father's death, Edward VIII summarily ordered that the clocks at Sandringham be returned to Greenwich Mean Time, ending the tradition of Sandringham Time begun by his grandfather over 50 years earlier. Edward had rarely enjoyed his visits to Sandringham, either in his father's time or that of his grandfather. He described a typical dinner at the house in a letter to his then mistress Freda Dudley Ward, dated 26 December 1919; "it's too dull and boring for words. Christ how any human beings can ever have got themselves into this pompous secluded and monotonous groove I just can't imagine". In another letter, evenings at the "big house" – Edward stayed at York Cottage with his father – were recorded as "sordidly dull and boring". His antipathy to the house was unlikely to have been lessened by his late father's will, which was read to the family in the saloon at the house. His brothers were each left £750,000 while Edward was bequeathed no monetary assets beyond the revenues from the Duchy of Cornwall. A codicil also prevented him from selling the late King's personal possessions; Lascelles described the inheritance as "the Kingship without the cash".Edward's concerns regarding his income led him immediately to focus on the expense associated with running his late father's private homes. Sandringham he described as a "voracious white elephant", and he asked his brother George to undertake a review of the management of the estate, which had been costing his father £50,000 annually in subsidies at the time of his death. The review recommended significant retrenchments, and its partial implementation caused considerable resentment among the dismissed staff. Edward spent a single night of his reign at the house, bringing Wallis Simpson for a shooting party in October 1936. The party was interrupted by a request to meet with prime minister Stanley Baldwin, and having arrived on a Sunday, the King returned to Fort Belvedere the next day. He never returned to Sandringham; and, his attention diverted by the impending crisis arising from his attachment to Simpson, within two months of his only visit to the house as King, he had abdicated. On his abdication, as Sandringham and Balmoral Castle were the private property of the monarch, it was necessary for King George VI to purchase both properties. The price paid, £300,000, was a cause of friction between the new King and his brother. 
Question: What is the full name of the person who ended the tradition of Sandringham Time begun by his grandfather?
