From CalTech website: "You will find the Norman W. Church Laboratory for Chemical Biology, a building with an unusual history. In the 1930s, when a horse named Proclivity—owned by Norman Church—won an important race at Santa Anita Race Track, it was claimed that Proclivity had been doped. To clear his name and that of his horse, Mr. Church called on Caltech’s Arnold Beckman,

then an assistant professor of chemistry, who found no evidence of any doping of the horse. Later, after reading about Caltech’s work in chemical biology, Norman Church donated the funds for this building. It was in this lab that the late Nobel laureate Roger Sperry discovered that the left and right hemispheres of our brains each have unique capabilities."
