Ask any long-time stargazer who has had the greatest impact on amateur astronomy, and two names will surely come up.
The first is
Russel W. Porter, who (with help from Albert Ingalls of
Scientific American) jump-started amateur telescope making in the 1920s. Every year more than 1,000 amateur astronomers still gather atop Breezy Hill in southern Vermont, where Porter and the Springfield Telescope Makers first gathered to test-drive their glass-and-metal creations.
The other is John Dobson, who turned telescope making on its head during the 1960s and '70s by using simple materials to produce low-cost, large-aperture reflectors. Today millions of stargazers worldwide use Dobsonian telescopes to sweep the sky, though (as Dobson himself will tell you) these are really just Newtonian reflectors affixed to the simple alt-azimuth wooden mounts that he popularized.
Dobson turns 95 on September 14th, and astronomy activist Thilina Heenatigala wants everyone to join him in sending birthday wishes. You can either send a message to
