I want to know the answer to the following question:
When did Whitehead go to America?
All the background I'm provided with is that "He was elected Dean of the Faculty of Science at the University of London in late 1918 (a post he held for four years), a member of the University of London's Senate in 1919, and chairman of the Senate's Academic (leadership) Council in 1920, a post which he held until he departed for America in 1924.". Is that enough to answer the question?
Answer: yes
