“In 1968 I offered to write for the National Air and Space Museum in Washington D. C. – without fee – the official monograph on Whitehead. [ ] But in the unsavoury atmosphere that has now arisen, I have felt it my duty to relieve the Museum of their acceptance of my offer, as I did not want to see my friends and colleagues there get caught up in a shabby political brawl. For some member of Congress might well have felt it his duty to inquire why a respected national museum dared have a scoundrelly and bigoted old English historian write on one of Connecticut’s most favoured sons - indeed a son who now has his own 'day' in the State Calender, the 'Gutave Whitehead Day'.”
