Telescope Designer and Astronomer John Dobson, 1915-2014

As noted by Sky & Telescope, SpaceWatchtower, and many other sources, astronomer and telescope innovator John Dobson died yesterday in Burbank, California, at the age of 98. He's famous as an inspiration for others to explore astronomy, in part through the San Francisco Sidewalk Astronomers, which he co-founded in 1967, and as designer of the telescope variety which bears his name.
