Dr. Francis Pinchot was a scientist who worked at Comstock House. He interviewed Daisy Fitzroy over a period of a week. After Daisy scored even higher on an intellect test than Dr. Pinchot himself, it was suggested that the scientists at Comstock House should perform a lobotomy on Daisy to make her more servile.
As Daisy's lobotomy was planned, Dr. Pinchot tried to intervene. Despite his help, Daisy shot and killed him before escaping.
