A quick google reveals that Marion Lucy, Walter's wife, was the designer of the Unitarian Church of All Souls, Evanston, Illinois... I don't know about Walter himself... But yes, I did know he was a Georgist..

Interestingly, I believe the vietnamese did actually consider buying up britain's mad cows in order to clear fields of cluster bombs

Now I though that was a laconic joke from Phonmh Penh!
