Outside of Shannon's academic pursuits, he was interested in juggling, unicycling, and chess. He also invented many devices, including a Roman numeral computer called THROBAC, and juggling machines. He built a device that could solve the Rubik's Cube puzzle. Shannon also invented flame-throwing trumpets, rocket-powered frisbees, and plastic foam shoes for navigating a lake, by wearing which it would appear to an observer as if Shannon were walking on water. Shannon designed the Minivac 601, a digital computer trainer to teach business people about how computers functioned. It was sold by the Scientific Development Corp starting in 1961. He is further considered the co-inventor of the first wearable computer along with Edward O. Thorp. The device was used to improve the odds when playing roulette.
=== Personal life === Shannon married Norma Levor, a wealthy, Jewish, left-wing intellectual in January 1940. The marriage ended in divorce a year later. Levor later married Ben Barzman. Shannon met his second wife, Mary Elizabeth Moore (Betty), when she was a numerical analyst at Bell Labs. They were married in 1949. Betty assisted Claude in building some of his most famous inventions. They had three children. Shannon presented himself as apolitical and an atheist.
=== Tributes and legacy ===
There are six statues of Shannon sculpted by Eugene Daub: one at the University of Michigan; one at MIT in the Laboratory for Information and Decision Systems; one in Gaylord, Michigan; one at the University of California, San Diego; one at Bell Labs; and another at AT&T Shannon Labs. The statue in Gaylord is located in the Claude Shannon Memorial Park. After the breakup of the Bell System, the part of Bell Labs that remained with AT&T Corporation was named Shannon Labs in his honor. In June 1954, Shannon was listed as one of the top 20 most important scientists in America by Fortune. In 2013, information theory was listed as one of the top 10 revolutionary scientific theories by Science News. According to Neil Sloane, an AT&T Fellow who co-edited Shannon's large collection of papers in 1993, the perspective introduced by Shannon's communication theory (now called "information theory") is the foundation of the digital revolution, and every device containing a microprocessor or microcontroller is a conceptual descendant of Shannon's publication in 1948: "He's one of the great men of the century. Without him, none of the things we know today would exist. The whole digital revolution started with him." The cryptocurrency unit shannon (a synonym for gwei, one billion wei) is named after him. Shannon is credited by many as single-handedly creating information theory and for laying the foundations for the Digital Age. His achievements are considered to be on par with those of Albert Einstein, Sir Isaac Newton, and Charles Darwin. A Mind at Play, a biography of Shannon written by Jimmy Soni and Rob Goodman, was published in 2017. They described Shannon as "the most important genius you’ve never heard of, a man whose intellect was on par with Albert Einstein and Isaac Newton". Consultant and writer Tom Rutledge, writing for Boston Review, stated that "Of the computer pioneers who drove the mid-20th-century information technology revolution—an elite men’s club of scholar-engineers who also helped crack Nazi codes and pinpoint missile trajectories—Shannon may have been the most brilliant of them all." Electrical engineer Robert Gallager stated about Shannon that "He had this amazing clarity of vision. Einstein had it, too – this ability to take on a complicated problem and find the right way to look at it, so that things become very simple." In an obituary by Neil Sloane and Robert Calderbank, they stated that "Shannon must rank near the top of the list of major figures of twentieth century science". Due to his work in multiple fields, Shannon is also regarded as a polymath. Historian James Gleick noted the importance of Shannon, stating that "Einstein looms large, and rightly so. But we’re not living in the relativity age, we’re living in the information age. It’s Shannon whose fingerprints are on every electronic device we own, every computer screen we gaze into, every means of digital communication. He’s one of these people who so transform the world that, after the transformation, the old world is forgotten." Gleick further noted that "he created a whole field from scratch, from the brow of Zeus". On April 30, 2016, Shannon was honored with a Google Doodle to celebrate his life on what would have been his 100th birthday. The Bit Player, a feature film about Shannon directed by Mark Levinson premiered at the World Science Festival in 2019. Drawn from interviews conducted with Shannon in his house in the 1980s, the film was released on Amazon Prime in August 2020. Claude, the large language model developed by artificial intelligence research company Anthropic, is partially named in honor of Shannon.
== The Mathematical Theory of Communication ==
=== Weaver's Contribution === Shannon's The Mathematical Theory of Communication, begins with an interpretation of his own work by Warren Weaver. Although Shannon's entire work is about communication itself, Warren Weaver communicated his ideas in such a way that those not acclimated to complex theory and mathematics could comprehend the fundamental laws he put forth. The coupling of their unique communicational abilities and ideas generated the Shannon-Weaver model, although the mathematical and theoretical underpinnings emanate entirely from Shannon's work after Weaver's introduction. For the layman, Weaver's introduction better communicates The Mathematical Theory of Communication, but Shannon's subsequent logic, mathematics, and expressive precision was responsible for defining the problem itself.
