Lecture Tonight

In the days before electronic mass-media, ordinary people who wanted to learn about things outside of a school or college could do so one of two ways: read about it, or attend a public lecture. Back in 1926, my great-grandfather Elbert H. Clarke offered a series of lectures on the stars, illustrated with lantern slides made using the 100-inch Hooker telescope on Mt. Wilson, which had been completed just eight years previously and was at the time the largest in the world. For his lectures, he charged just 25 cents, the equivalent of about $3.50 today.
