61 Hoe, Richard March
SUBJECT AREA: Paper and printing[br]b. 12 September 1812 New York, USAd. 7 June 1886 Florence, Italy[br]American inventor of the rotary printing press.[br]He was the son of Robert Hoe, a printer who improved the cylinder press invented by David Napier. At the age of 15 he entered his father's business, taking full control of it three years later. Newspaper publishers demanded ever-increasing speeds of output from the printing press, and Hoe was one of those who realized that the speed was limited by the reciprocating action of the flat-bed machine. In 1846 he constructed a rotary press in which a central cylinder carried the type and flat sheets of paper were fed to smaller impression cylinders ranged around it. This kind of press, with four impression cylinders, was first used to print the Philadelphia Public Ledger in 1847, and was able to print 8,000 papers per hour. Such presses reigned supreme for newspaper printing in many countries for twenty-five years: in 1857, for example, The Times had a ten-feeder machine making 20,000 impressions per hour. Even so, the quest for speed, now limited by the single-sheet feed, continued. William Bullock (1813–67) introduced continuous roll or web feed for the Philadelphia Inquirer in 1865, and the next year The Times followed suit with the web-fed Walter press. In 1871 Hoe devised a machine that combined all the advantages of the existing machines, producing a rotary, web, perfecting (printing on both sides of the paper at once) machine, first used in the office of the New York Tribune. Ten years later the Hoe Company devised a folding machine to fold the copies as they came off the press: the modern newspaper printing press had arrived. In addition to his contributions to the printing industry, Hoe was a good employer, arranging free evening classes and other welfare services for his apprentices.[br]Further ReadingR.Hoe, 1902, A Short History of the Printing Press, New York.

62 Mikoyan, Artem Ivanovich
SUBJECT AREA: Aerospace[br]b. 5 August 1905 Sanain, Armeniad. 9 December 1970 Moscow, Russia[br]Armenian aircraft designer.[br]Mikoyan graduated from the Zhukovsky Military Aircraft Academy in 1936. His first major design project was in response to an official requirement, issued in December 1940, for a single-engined fighter with performance equating to those then in service with the British, French and German air forces. In conjunction with M.L. Gurevich, a mathematician, and in a bare four months, he produced a flying prototype, with a top speed of 401 mph (645 km/h), that entered service as the MiG-1 in 1941. The Mikoyan and Gurevich MiG-3 and MiG-5 followed, and they then designed the MiG-7 high-altitude fighter; however, the latter never came into service on account of the decline of the German air force.The Second World War MiG fighters were characterized by high speed, good protection and armament, but they had poor manoeuvrability. In 1945, however, Mikoyan began to study Western developments in jet-powered aircraft. The result was a series of jet fighters, beginning with the MiG-9A, through the MiG-11, to the MiG-15 that gave the Allied air forces such a shock when it first appeared during the Korean War. The last in the series in which Mikoyan himself was involved was the MiG-23, which entered service in 1967. The MiG series lived on after both his and Gurevich's (1976) deaths, with one of the latest models being the MiG-31.[br]Principal Honours and DistinctionsDeputy to the Supreme Soviet 1950, 1954, 1958.
