Herbert Maryon

Herbert Maryon.
Herbert Maryon (1874–1965) was an English sculptor, conservator, goldsmith, archaeologist and authority on ancient metalwork. Maryon was the first director of the Arts and Crafts–inspired Keswick School of Industrial Art, then taught at the universities of Reading and Durham until 1939. During this time he designed the University of Reading War Memorial, excavated one of the oldest gold artefacts in Britain, and authored the standard Metalwork and Enamelling. Maryon left retirement to join the British Museum, and is best known for his conservation work on the Sutton Hoo ship-burial, including restorations of the shield, the drinking horns, and the iconic Sutton Hoo helmet. In other work he restored a Roman helmet, coined the term pattern welding, and wrote a paper influencing a painting by Salvador Dalí. Maryon was appointed to the Order of the British Empire in 1956; asked by Queen Elizabeth II what he did, Maryon responded: "Well, Ma'am, I am a sort of back room boy at the British Museum."

Valston Hancock

Valston Hancock.
Valston Hancock (31 May 1907 – 29 September 1998) was a senior commander in the Royal Australian Air Force (RAAF). A graduate of the Royal Military College, Duntroon, Hancock transferred to the RAAF in 1929 and qualified as a pilot. After fifteen years of occupying staff and training posts, he saw combat in the Aitape–Wewak campaign of the Pacific War during 1945. Flying Bristol Beaufort light bombers, he led No. 100 Squadron, and later No. 71 Wing, earning the Distinguished Flying Cross. After the war, Hancock became the inaugural commandant of RAAF College, followed by a succession of senior positions, before being promoted to air marshal and serving as Chief of the Air Staff from 1961 to 1965. He was knighted in 1962. In his role as the Air Force's senior officer, Hancock continued the policy of developing a chain of forward airfields in Northern Australia. He also evaluated potential replacements for the RAAF's English Electric Canberra bomber.

Rigel

Rigel.
Rigel is a blue supergiant star in the constellation of Orion, approximately 860 light-years (260 pc) from Earth. It is the brightest and most massive component of a star system of at least four stars that appear as a single blue-white point of light to the naked eye. A star of spectral type B8Ia, Rigel is calculated to be anywhere from 61,500 to 363,000 times as luminous as the Sun, and 18 to 24 times as massive. Its radius is over 70 times that of the Sun, and its surface temperature is 12,100 K. Rigel varies slightly in brightness, its apparent magnitude ranging from 0.05 to 0.18. It is classified as an Alpha Cygni variable. It is generally the seventh-brightest star in the night sky and is usually the brightest star in Orion, though it is occasionally outshone by Betelgeuse. With an estimated age of 7 to 9 million years, Rigel has exhausted its core hydrogen fuel, expanded and cooled to become a supergiant. It will end its life as a type II supernova.
