Who was the first woman to train and ride an AMERICAN horse in the Olympics?

Question

And which year was it??

Answer 1

I'm not sure about some of the other disciplines, but if I recall correctly, the first American woman to train and ride an Eventer was Lana Wright Turner, I think in 1952. With show jumping and dressage, I am not as sure. I do know that prior to 1952, women were largely prohibited from competing because of their gender- a sitiuation that has since been corrected, thank heavens !!
