Russell Lincoln Ackoff (February 12, 1919 – October 29, 2009) was an American organizational theorist, consultant, and Anheuser-Busch Professor Emeritus of Management Science at the Wharton School, University of Pennsylvania. Ackoff was a pioneer in the field of operations research, systems thinking and management science. Biography Russell L. Ackoff was born on February 12, 1919, in Philadelphia to Jack and Fannie (Weitz) Ackoff. He received his bachelor degree in architecture at the University of Pennsylvania in 1941. After graduation, he taught at Penn for one year as an assistant instructor in philosophy. From 1942 to 1946, he served in the U.S. Army in the Philippines. He returned to study at the University of Pennsylvania, where he received his doctorate in philosophy of science in 1947 as C. West Churchman’s first doctoral student. He also received a number of honorary doctorates, from 1967 and onward. From 1947 to 1951 Ackoff was assistant professor in philosophy and mathematics at the Wayne State University. He was associate professor and professor of operations research at Case Institute of Technology from 1951 to 1964. In 1961 and 1962 he was also visiting professor of operational research at the University of Birmingham. From 1964 to 1986 he was professor of systems sciences and professor of management science at the Wharton School at the University of Pennsylvania. Nicholson and Myers (1998) report that, in the 1970s and 1980s, the Social Systems Sciences Program at the Wharton School was "noted for combining theory and practice, escaping disciplinary bounds, and driving students toward independent thought and action. The learning environment was fostered by distinguished standing and visiting faculty such as Eric Trist, C. West Churchman, Hasan Ozbekhan, Thomas A. Cowan, and Fred Emery". Beginning in 1979, Ackoff worked together with John Pourdehnad as consultants in a broad range of industries including aerospace, chemicals, computer equipment, data services and software, electronics, energy, food and beverages, healthcare, hospitality, industrial equipment, automotive, insurance, metals, mining, pharmaceuticals, telecommunications, utilities, and transportation. From 1986 to 2009, Ackoff was professor emeritus of the Wharton School, and chairman of Interact, the Institute for Interactive Management. From 1989 to 1995 he was visiting professor of marketing at Washington University in St. Louis. Ackoff was president of Operations Research Society of America (ORSA) from 1956 to 1957, and he was president of the International Society for the Systems Sciences (ISSS) in 1987. In 1965 Ackoff was elected as a Fellow of the American Statistical Association. He was elected to the 2002 class of Fellows of the Institute for Operations Research and the Management Sciences. He was awarded an honorary Doctor of Science at the University of Lancaster, UK in 1967. He got a Silver Medal from the Operational Research Society in 1971. Other honors came from the Washington University in St. Louis in 1993, the University of New Haven in 1997, the Pontificia Universidad Catolica Del Peru, Lima in 1999 and the University of Lincolnshire & Humberside, UK in 1999. That year from the UK Systems Society he got an Award for outstanding achievement in Systems Thinking and Practice. Ackoff married Alexandra Makar on July 17, 1949. The couple had three children: Alan W., Karen B., and Karla S. After his wife's death, Ackoff married Helen Wald on December 20, 1987. Between 2003 and 2007, Ackoff delivered an annual series of public lectures, both half-day and full-day, for which the Ackoff family has granted permission for public viewing at this link. Russell L. Ackoff died unexpectedly Thursday, October 29, 2009, after complications of hip replacement surgery. Work Throughout the years Ackoff's work in research, consulting and education has involved more than 250 corporations and 50 governmental agencies in the U.S. and abroad. Operations research Russell Ackoff started his career in operations research at the end of the 1940s. His 1957 book Introduction to Operations Research, co-authored with C. West Churchman and Leonard Arnoff, was one of the first publications that helped define the field. The influence of this work, according to Kirby and Rosenhead (2005), "on the early development of the discipline in the USA and in Britain in the 1950s and 1960s is hard to over-estimate". In the 1970s Ackoff became one of the most important critics of the so-called "technique-dominated Operations Research", and starting proposing more participative approaches. His critiques, according to Kirby and Rosenhead (2005), "had little resonance within the USA, but were picked up both in Britain, where they helped to stimulate the growth of Problem Structuring Methods, and in the systems community world-wide", such as soft systems methodology from Peter Checkland. Purposeful systems In 1972 Ackoff wrote a book with Frederick Edmund Emery about purposeful systems, which focused on the question how systems thinking relates to human behaviour. "Individual systems are purposive", they said, "knowledge and understanding of their aims can only be gained by taking into account the mechanisms of social, cultural, and psychological systems". Any human-created systems can be characterized as "purposeful system" when its "members are also purposeful individuals who intentionally and collectively formulate objectives and are parts of larger purposeful systems". Other characteristics are: "A purposeful system or individual is ideal-seeking if... it chooses another objective that more closely approximates its ideal". "An ideal-seeking system or individual is necessarily one that is purposeful, but not all purposeful entities seek ideals", and "The capability of seeking ideals may well be a characteristic that distinguishes man from anything he can make, including computers". According to Kirby and Rosenhead (2005), "the fact that these systems were experiencing profound change could be attributed to the end of the "Machine Age" and the onset of the "Systems Age". The Machine Age, bequeathed by the Industrial Revolution, was underpinned by two concepts – reductionism (everything can in the end be decomposed into indivisible parts) and mechanism (cause-effect relationships)". Hereby "all phenomena were believed to be explained by using only one ultimately simple relationship, cause-effect", which in the Systems Age are replaced by expansionism and teleology with producer-product replacing cause-effect. "Expansionism is a doctrine maintaining that all objects and events, and all experiences of them, are parts of larger wholes." According to Ackoff, "the beginning of the end of the Machine Age and the beginning of the Systems Age could be dated to the 1940s, a decade when philosophers, mathematicians, and biologists, building on developments in the interwar period, defined a new intellectual framework". ....
