text: Stanley graduated cum laude from Princeton University in 1895 where he had also been a gifted athlete on the varsity tennis team. He had been showing signs of progressively worsening mental illness. In September 1906, he was hospitalized for over a year at McLean Hospital and was originally diagnosed with dementia praecox, an early label for what is now today known as schizophrenia.
  In June 1908, Stanley was moved to the McCormicks' Riven Rock estate in Montecito, California, where his schizophrenic older sister, Mary Virginia, had lived from 1898 to 1904 before being placed in a Huntsville, Alabama, sanitarium. While there, he was examined by the prominent German psychiatrist Emil Kraepelin and diagnosed with the catatonic form of dementia praecox. In 1909, Stanley was declared legally incompetent and his guardianship divided between Katharine and the McCormick family.
  Women's rights activist
  Katharine's plea for gender equality was apparent from early on. As an undergraduate at MIT, she confronted administration officials. MIT required that women wear hats (fashionably spruced up with feathers). Katharine refused. She argued that it was a fire hazard for feathered hats to be worn in laboratories. As a result, MIT's administration changed their policies.
  In 1909 McCormick spoke at the first outdoor rally for woman suffrage in Massachusetts. She became vice president and treasurer of the National American Woman Suffrage Association and funded the association's publication the Woman's Journal.
