Pen name “O Henry” (1862-1910) US author. Born in Greensboro, North Carolina, Porter left home at an early age. Settling in Texas, he was convicted of embezzlement 1899 and served several years in prison. It was then that he began to write short stories under the distinctive pen name “O Henry.” After his release 1902, he moved to New York City, where he contributed stories, many with surprise endings, to the New York World. Among the published collections of O Henry’s most famous stories are ‘The Four Million’ (including “The Gift of the Magi”) 1906, ‘The Voice of the City’ 1908, and ‘Rolling Stones’ 1913.
(1917-1985) English biochemist. In 1962 he proposed a structure for human immunoglobulin (antibody) in which the molecule was seen as consisting of four chains. He was awarded the 1972 Nobel Prize for Physiology or Medicine.
Porter was born in Liverpool and studied there and at Cambridge. He became professor of immunology at St Mary's Hospital Medical School, London, 1960; from 1967 he was professor of biochemistry at Oxford.
Basing his research on the work of US immunologist Karl Landsteiner, Porter studied the structural basis of the biological activities of antibodies, proposing in 1962 a structure for gamma-globulin. He also worked on the structure, assembly, and activation mechanisms of the components of a substance known as complement. This is a protein that is normally present in the blood, but disappears from the serum during most antigen–antibody reactions. In addition, Porter investigated the way in which immunoglobulins interact with complement components and with cell surfaces.
(1947-) US management theorist and expert on competitive strategy. His first book, Competitive Strategy 1980, set out his theory on strategies for competitive advantage and is regarded by many as the definitive work in the field. He applied the same theory to countries in his Competitive Advantage of Nations 1990 to explain why some countries are richer than others.
His “competitive strategy” theory is based on an analysis of a company’s competitive position within its environment, using the “five forces” that drive competition. These forces are: the relative strength of buyers or customers; the relative strength of suppliers; the relative ease with which potential new competitors can enter the market; the potential availability of substitutes; and rivalry between competing firms.
Porter is professor of management at Harvard Business School.
He further identified five generic descriptions of industries —fragmented, emerging, mature, declining, and global— and two generic competitive strategies: cost and leadership, and differentiation. A firm can establish cost leadership by providing comparable buyer value more efficiently than others in the market, and differentiation advantage by performing activities at a comparable cost to competitors but in a unique way that creates more buyer value and hence commands a premium price.
(1890-1980) US writer. She published three volumes of short stories (Flowing Judas 1930, Pale Horse, Pale Rider 1939, and The Leaning Tower 1944); a collection of essays, The Days Before 1952; and the allegorical novel Ship of Fools 1962 (filmed 1965). Her Collected Short Stories 1965 won a Pulitzer Prize.
Born in Indian Creek, Texas, Porter began her writing career after high school, working on newspapers and as a freelance, and lived in Mexico and then in Europe. Her short stories are notable for a depth and complexity usually found only in novels. Her correspondence is collected in Letters of Katherine Anne Porter 1990.
(1911-1984) Australian novelist, short-story writer, playwright, and poet.
He is best known for his short stories, collected in seven volumes, and for his three autobiographical works The Watcher on the Cast-Iron Balcony 1963, The Paper Chase 1966, and The Extra 1975.
(1920-) English chemist. From 1947 he and Ronald Norrish developed a technique by which flashes of high energy are used to bring about extremely fast chemical reactions. They shared a Nobel Prize 1967.
Porter was born in Stainforth, Yorkshire, and studied at Leeds. After World War II he carried out research at Cambridge under Norrish. Porter was professor at Sheffield 1955–66, director of the Royal Institution 1966–85, and president of the Royal Society 1985–90. In the 1960s he made many appearances on British television.
Porter began using quick flashes of light to study transient species in chemical reactions, particularly free radicals and excited states of molecules. In 1950 he could detect entities that exist for less than a microsecond; by 1975, using laser beams, he had reduced the time limit to a picosecond (10-12 sec). His early work dealt with reactions involving gases (mainly chain reactions and combustion reactions), but he later extended the technique to solutions and also studied the processes that occur in the first nanosecond of photosynthesis in plants. He developed a method of stabilizing free radicals by trapping them in the structure of a supercooled liquid (a glass), a technique called matrix isolation.
(1869-1941) US director, a pioneer of silent films. His 1903 film The Great Train Robbery lasted an unprecedented 12 minutes and contained an early use of the close-up. More concerned with the technical than the artistic side of his films, which include The Teddy Bears 1907 and The Final Pardon 1912, Porter abandoned filmmaking 1916.
(Albert) (1891-1964) US composer and lyricist of witty musical comedies. His shows include The Gay Divorce 1932 (filmed 1934 as The Gay Divorcee), Anything Goes 1934, Kiss Me, Kate 1948, and Silk Stockings 1955. He also wrote movie musicals, such as Born to Dance 1936 and High Society 1956.
Born in Indiana of an affluent family, Porter attended Yale and Harvard universities, then did military service during World War I. He became a member of the fashionable set in Europe during the 1920s and established himself with the revue Paris 1928. His clever, sophisticated lyrics and appealing melodies have made many of his songs standards, including ‘Night and Day’, ‘I Get a Kick Out of You’, ‘Begin the Beguine’, ‘My Heart Belongs to Daddy’, and ‘You’re the Tops’.
