7 Deceased Members and Friends William B. Whiddon - San Pedro, CA Longtime AAVSO Member, founding member of SBAS - The South Bay Astronomical Society (Redondo Beach, CA). William passed away in October of 2005 due to complications from acute leukemia. He taught astronomy labs at the North Texas observatory before joining TRW (later acquired by Northrop Grumman Space Technology). He earned a graduate certificate in astronautical engineering from the University of California at Los Angeles and for most of his career worked as a systems engineer on satellite programs. At the time of his death he was chief engineer for the James Webb Space Telescope. With his wife, Nina Whiddon, he photographed total solar eclipses throughout the world, including the 2003 eclipse over Antarctica. They returned to Antarctica in 2005 with a meteorite search team and traveled to the South Pole. One of Whiddons photographs of Comet Hale-Bopp appears in Robert Burnhams book Great Comets.
