Iowa has sent at least one wrestler to every Summer Olympics since 1920. Thomas Gilman is the latest.

Three things in life are certain: Death, taxes and Iowa wrestlers competing in the Olympics.

Seriously.

Since 1920, at least one wrestler either born in Iowa or competing collegiately in Iowa has represented Team USA wrestling in the Olympics. That's 24 straight Olympics, for those counting at home. Former Hawkeye wrestler Thomas Gilman is the latest, wrestling at 57 kilograms in the Tokyo Summer Olympics.

Out of those Olympic wrestlers from Iowa, 13 have won gold medals. Seven of those came in the last nine Olympics (Jake Varner in 2012, Cael Sanderson in 2004, Tom Brands in 1996, Kevin Jackson in 1992, and Lewis Banach, Ed Banach and Lou Banach in 1984).

Here's a list of every wrestler from Iowa to compete in the Olympics:
