Geoffrey Taucer was the internet name of an American gymnast.
He competed at the Sand Dollar / Whitlow Invitational Invite. The first person I’ve seen compete this vault. Though the landing was very under-rotated … he did get credit for the vault from the judges. That means his feet hit first.

UPDATE: Geoffrey Taucer’s real name is Jeremy Waters. You can call it the “Waters”, not the Taucer.
