Dennis Tito is a United States multimillionaire who gained celebrity status by becoming the first space tourist to pay for his own ticket.
In 1972 he founded Wilshire Associates, a leading provider of investment management, consulting and technology services in Santa Monica, California, and he serves an international clientele representing assets of $12.5 trillion. Wilshire relies on the field of quantitative analytics, which uses mathematical tools to analyze market risks - a methodology Tito is credited with helping to develop by applying the same techniques he used to determine a spacecraft's path at JPL.
Through an arrangement with space tourism company Space Adventures, Ltd., Tito joined Soyuz TM-32 on April 28th, 2001, spending 7 days, 22 hours, 4 minutes in orbit, and docked with the ISS. He performed several scientific experiments in orbit that should be useful for his company and business. Tito paid $20 million for his trip.
He was appointed to the Los Angeles Department of Water and Power Board of Commissioners in the 1990s and led the board to support the landmark 1994 state ruling protecting Mono Lake from excessive water diversions by the city.
Since returning from space, he has testified at the Senate Committee on Commerce, Science & Transportation, Subcommittee on Science, Technology, and Space and the House Committee on Science, Subcommittee on Space & Aeronautics Joint Hearing on "Commercial Human Spaceflight" on July 24, 2003
