In reply to Form follows beauty:
Visiting Glasgow, one expects a lot of Mackintosh, but he was marginal and designed few major buildings...
No doubt, but he was well felt across the pond ... no more so than in F.Ll.W's Prairie School.
Tomas Jefferson also had the right 'clients' didn't he tho ... and a very far reaching architectural influence at that.
One of my all time favorite architects from times past is Hawksmoor ...a London architect. His Westminster Abby towers are f'n awesome. Even tho he was schooled by Wren I consider Nicholas Hawksmoor to be a transitional architect who indeed had a crazy influence. In all his stuff there's a distinct edge to his ordering.
You don't get that with Niemeyer's work nor with his protégés such as Hadid and company ... ;)
