Louis Agassiz was a 19th-century Swiss-American biologist and geologist whose contributions to natural history were immense. He popularized the concept of ice ages and was a towering figure in American science during his lifetime. Stanford mounted the marble statue on the exterior of Building 420 -- then known as Jordan Hall -- in the Main Quad, honoring his legacy. Agassiz stared down from the second floor at passing students, a stone reminder of scientific achievement. That arrangement lasted until the earth decided otherwise.

The 1906 earthquake devastated much of the Stanford campus. Memorial Church lost its steeple. The new library, still under construction, was destroyed. And Agassiz pitched forward from his façade and buried his head in the ground. The New York Times later noted that the photograph of the great scientist upside-down, his body jutting into the air, became an iconic image of the earthquake. The statue itself survived without damage -- marble is surprisingly resilient when it lands on its head -- and was eventually reinstalled on the building. But the image endured longer than the statue's second mounting, a visual joke the campus never forgot.

Agassiz's scientific achievements coexisted with beliefs that history would judge harshly. He was a vocal proponent of polygenism -- the discredited theory that human races had separate biological origins, used to justify racial hierarchy and slavery. For over a century, this aspect of Agassiz's legacy was acknowledged but did not affect his place of honor on the Stanford campus. That changed in 2020, when the Stanford Department of Psychology, which now occupied the building, requested the statue's removal. The university complied, and in October 2020 the marble figure was taken down from the façade where it had stood (and fallen, and been reinstalled) for more than a hundred years. The removal came amid a broader national conversation about which historical figures deserve public commemoration, but the specifics of Agassiz's case -- his use of science to support racial hierarchy -- made the decision particularly pointed for a research university.

Building 420 still stands in Stanford's Main Quad, but the spot where Agassiz once gazed down is bare. The statue exists but is no longer on public display. What remains most vividly is the photograph from 1906: the great man inverted, his certainties literally upended, his head planted in the ground he once studied. It is an image that works on multiple levels now -- as earthquake documentation, as dark comedy, and as an unintentional metaphor for a scientific reputation that could not withstand closer examination. The pun about being great in the abstract but not in the concrete has outlasted every other piece of the story.
