Biographical / historical:

The Mount Wilson 60" telescope began as a gift from George Ellery Hale's father, William Hale, in 1894. In 1904, funding to finish the project was obtained, and once built, it became one of the most prolific and important telescopes in astronomical history.

The 100" Hooker telescope, funded in part by John D. Hooker and the Carnegie Institute of Washington, was completed in 1917. It was used to measure the precise diameter of stars for the first time. Edwin Hubble's work indicating the existence of galaxies outside our own, and the phenomena of redshift, was also completed with the help of the 100" telescope.
