When Theory Met the Stars: Albert Einstein’s Visit to Yerkes Observatory
In May 1921, Albert Einstein embarked on his very first tour of the United States. By this time, the German-born theoretical physicist was already a global celebrity. Two years earlier, during the solar eclipse of 1919, British astronomers led by Sir Arthur Eddington had successfully confirmed a key prediction of Einstein’s Theory of General Relativity: that massive objects like the Sun actually warp the space around them, bending the path of starlight passing nearby. As Einstein traveled across America to lecture at major universities and support scientific causes, his itinerary included a noteworthy excursion to a small, serene Midwest community: Williams Bay, Wisconsin. Located on the northern shore of Geneva Lake, this town was home to the Yerkes Observatory, one of the premier astronomical research institutions in the world.
