Question: When was the developer of Michigan State Integral Computer died?
Context: The 1993 Michigan State Spartans football team competed on behalf of Michigan State University in the Big Ten Conference during the 1993 NCAA Division I-A football season.  Head coach George Perles was in his 11th season with the Spartans.  Michigan State played their home games at Spartan Stadium in East Lansing, Michigan.  The Spartans went 6–6 overall and 4–4 in conference play.  Michigan State was invited to the 1993 Liberty Bowl and was defeated by Louisville, 7–18. Clarence Lester "Biggie" Munn (September 11, 1908 – March 18, 1975) was an American football player, coach, and college athletics administrator.  He was the head football coach at Albright College (1935–1936), Syracuse University (1946), and most notably Michigan State College (1947–1953), where his 1952 squad won a national championship.  Munn retired from coaching in 1953 to assume duties as Michigan State's athletic director, a position he held until 1971.  Each year, the Michigan State Spartans football team hands out the "Biggie Munn Award" to the team's most motivational player.  MSU's Munn Ice Arena, built in 1974, is named in his honor.  Munn was inducted into the College Football Hall of Fame as a coach in 1959, and, in 1961, he became Michigan State's first inductee into the Michigan Sports Hall of Fame.  He authored the coaching textbook "Michigan State Multiple Offense" in 1953. The 1966 Notre Dame vs. Michigan State football game is considered one of the greatest and most controversial games in college football history played between Michigan State and Notre Dame.  The game was played in Michigan State's Spartan Stadium on November 19, 1966.  Michigan State entered the contest 9–0 and ranked No. 2, while Notre Dame entered 8–0 and ranked No. 1.  Notre Dame elected not to try for a score on the final series; thus, the game ended in a 10–10 tie.  Notre Dame went on to win or share the national title in fourteen polls (including the AP and UPI); Michigan State won or shared in three minor polls, and Alabama, who finished with the only undefeated and untied record, won two minor polls. The Michigan State Spartans football program represents Michigan State University in college football at the NCAA Division I Football Bowl Subdivision level.  The Spartans are members of the Big Ten Conference.  Michigan State claims a total of six national championships (1951, 1952, 1955, 1957, 1965, and 1966); the AP Poll voted Michigan State as national champion one time (1952).  They have been named national champions twice in the Coaches Poll (1952 and 1965).  The Spartans have also won two Michigan Intercollegiate Athletic Association championships (1903 and 1905) and nine Big Ten championships (1953, 1965, 1966, 1978, 1987, 1990, 2010, 2013, and 2015). Michigan State University Observatory is an astronomical observatory owned and operated by Michigan State University.  It is located south of the Michigan State University campus in East Lansing, Michigan (USA), near the corner of Forest Rd and College Rd.  It has a Cassegrain telescope in its single dome.  Built by Boller and Chivens, the Michigan State University telescope was commissioned in 1969 and entered regular operation in 1970.  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.  Originally, single channel photoelectric photometry and photography using plates or film were the means of acquiring data.  The observatory was closed from 1981 until 1986, at a time when the university was having financial difficulties.  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.  Since the 1980s, a CCD camera has been employed as the main instrument and the Raytheon computer has been retired.  The International Astronomical Union has assigned the MSU Observatory identification code 766. Lyle James "Rocky" Rockenbach (March 1, 1915 – November 8, 2005) was an American football player.  He played college football for Michigan State College (later known as Michigan State University) from 1937 to 1939.  He blocked three punts in a single game against Temple in 1937.  He was a co-captain of the 1939 Michigan State team, and was also honored as the team's most valuable player.  After graduating from Michigan State, he became a high school coach in Howell, Michigan.  In the summer of 1943, he attempted a comeback as a professional football player for the Detroit Lions.  He appeared in nine games for the Lions during the 1943 NFL season. The 2006 Michigan State Spartans football team represented Michigan State University in the 2006 NCAA Division I FBS football season.  Michigan State competed as a member of the Big Ten Conference, and played their home games at Spartan Stadium in East Lansing, Michigan.  The Spartans were led by fourth-year head coach John L. Smith.  Smith had compiled a combined 18–18 record in his previous seasons at Michigan State, and he was fired after the 2006 season in which the team finished 4–8.  The Spartans did, however, set the record for the greatest comeback from a deficit in college football history. 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.  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.  Both teams are members of the Big Ten Conference.  The rivalry has been evidenced both on the court and off the court.  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. John von Neumann ( ; Hungarian: "Neumann János Lajos" , ] ; December 28, 1903 – February 8, 1957) was a Hungarian-American mathematician, physicist, and computer scientist.  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. 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.  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.
