Yes, she should be recognized at this Olympics. Many people became famous after they die. The U.S. should still honor this person even though she didn't know she was an Olympian. It doesn't matter if she knew she was an Olympian. We know that she was an Olympian, so we should recognize her as such.
Recognize her as an Olympian, even though it is a posthumous gesture. The earliest modern Olympics were in 1896, so I don't think they were perfect in event orchestration at the time. It will be nice especially if any of this woman's descendants are alive. They can now say their ancestor was an Olympian!
Margaret Abbott deserves acknowledgement for being the first American woman to win an Olympic gold medal. Her own family did not know the significance of her victory until nearly a century later. This summer's Olympic games are the perfect time to recognize her because it's the first time since her win that women will be competing in an individual golf event.
Now that the truth is out, her accomplishments need to be honored. She is one of the first people to win an Olympic medal and one of the first women to win. This is a big deal, and even though she is not here to be honored, young women and men need to know.
