The Brit equivalent of FLW might be Charles Voysey; in the 1900s both were building houses for the rich in a style that everybody copied for years to come:-
He wasn't as innovative as FLW and in fact you have to bit a bit of a specialist to see that they're innovative at all. Also, he never got a song written about him either, so if this is an Architecture Wars thread, I'll concede this round to the USA.
