Question: Which is the oldest place that Sandford was educated? Passage 1:St Jude's is constructed in yellow sandstone ashlar with a slate roof. Its plan is rectangular and consists of a nave and chancel in one cell with no division between them, a vestry attached to the east end of the chancel, and a bellcote on the gable at the west end. Above the bellcote is a canopy decorated with crockets. The west front contains a double door, above which is a triple lancet window with a circular window over it. At the corners are square turrets which become octagonal as they rise, and each is surmounted by a spire. On each side of the church are five pairs of lancet windows, each pair being separated by a buttress. Above the vestry at the east end is another triple lancet window, over which is a cricketed gable.
Passage 2:Folliott Herbert Sandford, the son of a barrister, was born on 28 October 1906. He was educated at Winchester College and New College, Oxford, where he obtained first-class degrees in Classics and in Law. He joined the Air Ministry as a civil servant in 1930, working as Principal Private Secretary to four Secretaries of State for Air between 1937 and 1940: Viscount Swinton, Sir Kingsley Wood, Sir Samuel Hoare and Sir Archibald Sinclair. In 1941 and 1942, he was attached to RAF Ferry Command in Montreal, Quebec, Canada; from 1942 to 1944, he was the secretary to the office of the Resident Minister for West Africa. He returned to the Air Ministry in 1944, rising from Assistant Under-Secretary of State to become Deputy Under-Secretary of State from 1947 to 1958. He was appointed a Companion of the Order of St Michael and St George (CMG) and a Knight Commander of the Order of the British Empire (KBE) in 1949. He became a Fellow of New College on his appointment as Registrar of the University of Oxford in 1958, succeeding Sir Douglas Veale, and held both positions until retiring in 1972. On his retirement, he was appointed an Honorary Fellow of New College and Wolfson College, and was awarded an honorary doctorate by the university. He was Master of the Skinners' Company from 1975 to 1976. He was twice married: to Gwendoline (nee Masters) from 1935 until her death in 1977, and then to Peggy Young (nee Odgear) from 1982 until her death in 1984. Sandford died on 5 July 1986. The historian Brian Harrison describes him as "unobtrusively providing expertise and continuity" and a hard worker, but one who "lacked Veale's vision and sense of proportion" and who suffered from having to try to match the standards set for the role by Veale.
Passage 3:In 2010, Deveron Projects commissioned Hamish Fulton to create a new walking work for Huntly. The resulting piece 21 Days in the Cairngorms (2010) featured two group slow-walks, as well as a group of walkers to see Fulton off on the first day of his twenty-day journey, and new and unusual experience for Fulton. This project inspired the development of the Walking Institute and a further focus on walking as an artistic medium. In 2012 Ethiopian artist Mihret Kebede developed Slow Marathon, an artistic project in response to her inability to walk from her hometown of Addis Ababa to Huntly. The project consisted of an accumulative marathon that included miles donated remotely by international participants, as well as two twenty-six mile walks in Huntly and Addis Ababa. Ultimately, over five-hundred individuals participated in the project and donated 14172.4 miles, a total of 540 marathons. The project has since become an annual event, created in conjunction with artists working with Devon Projects The 2013 Slow Marathon, Cabrach to Huntly, was held on John Muir Day and served as the official launch of the Institute. The 2014 event started at the Glenkindie on the edge of the Cairngorms National Park. Other Walking Institute projects have included: In the Footsteps of Nan Shepherd: a long distance walk looking by Simone Kenyon at issues, plights and pleasures of women walking in wilderness; Huntly Perambulator, a series of walks by Clare Qualmann looking at walking with prams; Hielan' Ways, a programme that included poetry (Alec Finlay), music (Paul Anderson) and art (Simone Kenyon, Gillian Russel). Hielan' Ways explored the old drover routes that cross north-east Scotland and culminated in a symposium with contributions from mountaineer Doug Scott , Turner Prize-winning artist Richard Long and the Cloud Appreciation Society. In 2015 Anthony Schrag completed The Lure of the Lost: A Contemporary Pilgrimage, a 2500km walk from Huntly to the Venice Biennale in Italy.
