In plowing through stacks of saved magazines, I found a Smithsonian from 2012 devoted tho the London Olympics. Lots of good stories, including one about the origins of the modern games (see my Much Wenlock post for more on that). Another thread running through the Olympic history story (well-written by Frank de Ford in his inimitable style) is the story of dipping the American flag, or not, in the opening procession.
I won't go into the whole thing, but an shot-putter named Ralph Rose failed to dip the Stars and Stripes to King Edward at the first London Olympics in 1908. Whether it was out of patriotism or simple oversight is a matter of debate ( Mr . Ford clearly favors the latter) it became a custom supported by the notion that the "flag dips to no earthly king". But at the 1932 Lake Placid Olympics, American bobsledder Billy Fiske did dip the flag to then-governor Franklin Roosevelt, thereby becoming the last American Olympian to do so.
Fiske won two gold medals in his sport, in 1928 ( St. Moritz) and 1932, and also competed in 1936 (Munich). He married an Englishwoman and stayed in England after attending Cambridge. He managed to join the RAF by presenting Canadian papers, was hailed as one of the best pilots, and died in 1940 on a mission.

There is a memorial to him in St. Paul's, dedicated July 4, 1941. The article says it is in the crypt, not in the American Chapel behind the altar, a place I love to visit every time we are in London. It next time I will go look for the plaque in the crypt.
Take care and stay healthy, everyone.
