IN: Toru Takemitsu (Wu Man Che , Takemitsu Toru, October 8, 1930 - February 20, 1996) pronounced [takemitsW to:rW] was a Japanese composer and writer on aesthetics and music theory. Largely self-taught, Takemitsu possessed consummate skill in the subtle manipulation of instrumental and orchestral timbre. He is famed for combining elements of oriental and occidental philosophy to create a sound uniquely his own, and for fusing opposites together such as sound with silence and tradition with innovation. He composed several hundred independent works of music, scored more than ninety films and published twenty books.

The influence of Olivier Messiaen on Takemitsu was already apparent in some of Takemitsu's earliest published works. By the time he composed Lento in Due Movimenti, (1950), Takemitsu had already come into possession of a copy of Messiaen's 8 Preludes (through Toshi Ichiyanagi), and the influence of Messiaen is clearly visible in the work, in the use of modes, the suspension of regular metre, and sensitivity to timbre. Throughout his career, Takemitsu often made use of modes from which he derived his musical material, both melodic and harmonic among which Messiaen's modes of limited transposition to appear with some frequency. In particular, the use of the octatonic, (mode II, or the 8-28 collection), and mode VI (8-25) is particularly common. However, Takemitsu pointed out that he had used the octatonic collection in his music before ever coming across it in Messiaen's music. In 1975, Takemitsu met Messiaen in New York, and during "what was to be a one-hour 'lesson' [but which] lasted three hours ... Messiaen played his Quartet for the End of Time for Takemitsu at the piano", which, Takemitsu recalled, was like listening to an orchestral performance. Takemitsu responded to this with his homage to the French composer, Quatrain, for which he asked Messiaen's permission to use the same instrumental combination for the main quartet, cello, violin, clarinet and piano (which is accompanied by orchestra). As well as the obvious similarity of instrumentation, Takemitsu employs several melodic figures that appear to "mimic" certain musical examples given by Messiaen in his Technique de mon langage musical, (see ex. 4). In 1977, Takemitsu reworked Quatrain for quartet alone, without orchestra, and titled the new work Quatrain II. On hearing of Messiaen's death in 1992, Takemitsu was interviewed by telephone, and still in shock, "blurted out, 'His death leaves a crisis in contemporary music!'" Then later, in an obituary written for the French composer in the same year, Takemitsu further expressed his sense of loss at Messiaen's death: "Truly, he was my spiritual mentor ... Among the many things I learned from his music, the concept and experience of color and the form of time will be unforgettable." The composition Rain Tree Sketch II, which was to be Takemitsu's final piano piece, was also written that year and subtitled "In Memoriam Olivier Messiaen".

IN: Herbert Alexander Simon (June 15, 1916 - February 9, 2001) was an American economist and political scientist whose primary interest was decision-making within organizations and is best known for the theories of "bounded rationality" and "satisficing". He received the Nobel Prize in Economics in 1978 and the Turing Award in 1975. His research was noted for its interdisciplinary nature and spanned across the fields of cognitive science, computer science, public administration, management, and political science. He was at Carnegie Mellon University for most of his career, from 1949 to 2001.

Simon was a pioneer in the field of artificial intelligence, creating with Allen Newell the Logic Theory Machine (1956) and the General Problem Solver (GPS) (1957) programs. GPS may possibly be the first method developed for separating problem solving strategy from information about particular problems. Both programs were developed using the Information Processing Language (IPL) (1956) developed by Newell, Cliff Shaw, and Simon. Donald Knuth mentions the development of list processing in IPL, with the linked list originally called "NSS memory" for its inventors. In 1957, Simon predicted that computer chess would surpass human chess abilities within "ten years" when, in reality, that transition took about forty years. In the early 1960s psychologist Ulric Neisser asserted that while machines are capable of replicating "cold cognition" behaviors such as reasoning, planning, perceiving, and deciding, they would never be able to replicate "hot cognition" behaviors such as pain, pleasure, desire, and other emotions. Simon responded to Neisser's views in 1963 by writing a paper on emotional cognition, which he updated in 1967 and published in Psychological Review. Simon's work on emotional cognition was largely ignored by the artificial intelligence research community for several years, but subsequent work on emotions by Sloman and Picard helped refocus attention on Simon's paper and eventually, made it highly influential on the topic. Simon also collaborated with James G. March on several works in organization theory. With Allen Newell, Simon developed a theory for the simulation of human problem solving behavior using production rules. The study of human problem solving required new kinds of human measurements and, with Anders Ericsson, Simon developed the experimental technique of verbal protocol analysis. Simon was interested in the role of knowledge in expertise. He said that to become an expert on a topic required about ten years of experience and he and colleagues estimated that expertise was the result of learning roughly 50,000 chunks of information. A chess expert was said to have learned about 50,000 chunks or chess position patterns. He was awarded the ACM Turing Award, along with Allen Newell, in 1975. "In joint scientific efforts extending over twenty years, initially in collaboration with J. C. (Cliff) Shaw at the RAND Corporation, and subsequentially [sic] with numerous faculty and student colleagues at Carnegie Mellon University, they have made basic contributions to artificial intelligence, the psychology of human cognition, and list processing."

Were these programs used by others later on?
