Question: When was the developer of Michigan State Integral Computer died?

<P0-S0>  He made major contributions to a number of fields, including mathematics (foundations of mathematics, functional analysis, ergodic theory, representation theory, operator algebras, geometry, topology, and numerical analysis), physics (quantum mechanics, hydrodynamics, and quantum statistical mechanics), economics (game theory), computing (Von Neumann architecture, linear programming, self-replicating machines, stochastic computing), and statistics. <P0-S1> John von Neumann ( ; Hungarian: "Neumann János Lajos" , ] ; December 28, 1903 – February 8, 1957) was a Hungarian-American mathematician, physicist, and computer scientist. <SEP> <P1-S0> The Michigan–Michigan State basketball rivalry is a college basketball rivalry between Michigan Wolverines men's basketball and Michigan State Spartans men's basketball that is part of the larger intrastate rivalry between the University of Michigan and Michigan State University that exists across a broad spectrum of endeavors including their general athletic programs: Michigan Wolverines and Michigan State Spartans. <P1-S1>  On the field, the athletic rivalry includes the Paul Bunyan Trophy and the Michigan–Michigan State ice hockey rivalry, but extends to almost all sports and many other forms of achievement. <P1-S2>  Both teams are members of the Big Ten Conference. <P1-S3>  The rivalry has been evidenced both on the court and off the court. <P1-S4>  Among the off the court elements of the rivalry, recruiting of basketball talent has resulted in battles, the most notable of which turned into the University of Michigan basketball scandal when both schools sought the services of Mateen Cleaves. <SEP> <P2-S0> Michigan State University Observatory is an astronomical observatory owned and operated by Michigan State University. <P2-S1>  It is located south of the Michigan State University campus in East Lansing, Michigan (USA), near the corner of Forest Rd and College Rd. <P2-S2>  It has a Cassegrain telescope in its single dome. <P2-S3>  Built by Boller and Chivens, the Michigan State University telescope was commissioned in 1969 and entered regular operation in 1970. <P2-S4>  In 1974, what was at the time a state-of-the-art Raytheon Microcomputer was installed to function as a data gathering and control system. <P2-S5>  Originally, single channel photoelectric photometry and photography using plates or film were the means of acquiring data. <P2-S6>  The observatory was closed from 1981 until 1986, at a time when the university was having financial difficulties. <P2-S7>  It was reopened in the spring of 1986 on the occasion of the return of Comet Halley and has been in regular operation ever since. <P2-S8>  Since the 1980s, a CCD camera has been employed as the main instrument and the Raytheon computer has been retired. <P2-S9>  The International Astronomical Union has assigned the MSU Observatory identification code 766. <SEP> <P3-S0> The MISTIC, or "Michigan State Integral Computer", was the first computer system at Michigan State University and was built by its students, faculty and staff in 1956. <P3-S1>  Powered by vacuum tubes, its design was based on ILLIAC, the supercomputer built at University of Illinois at Urbana-Champaign, a descendent of the IAS architecture developed by John von Neumann.
