* Letters to the Mount Wilson Observatory are the subject of a permanent exhibition at the [[Museum of Jurassic Technology]] in [[Los Angeles, California]].

These letters were also collected in the book ''No One May Ever Have the Same Knowledge Again: Letters to Mt. Wilson Observatory 1915–1935'' ({{ISBN|0-9647215-0-3}}).

* The English poet [[Alfred Noyes]] was present for the "first light" of the Hooker telescope on November 2, 1917. Noyes used this night as the setting in the opening of ''Watchers of the Sky,'' the first volume in his trilogy ''The Torchbearers'', an epic poem about the history of science. According to his account of the night, the first object viewed in the telescope was Jupiter, and Noyes himself was the first to see one of the planet's moons through the telescope.<ref>{{cite book |title=Watchers of the Sky |url=https://archive.org/details/watcherssky00noyegoog |last=Noyes |first=Alfred |author-link=Alfred Noyes |date=1922 |publisher=New York, Frederick A.
