Born on this date in 1811 was Benjamin (Don Benito) Wilson, the namesake of Mt. Wilson, California, which is home to what were once the largest telescopes in the world, the 60″ Hale and the 100″ Hooker. Later, three solar telescopes were added on the mountain, two of which are still in use, as well as the CHARA array and active interferometers. It was here that Edwin Hubble first realized that the “spiral nebulae” were actually distant galaxies and discovered Cepheid variables in them.
