I’d say that Marlin Fitzwater is arguably the most famous Kansas State University grad.
Or maybe Kirstie Alley.
But here’s a list:
From my High School - Independence, Kansas -
Vivian Vance - actress, various TV shows
William Inge - playwright
From Bellaire High School in Houston, TX… Brent Spiner, also know as Data from Star Trek: The Next Generation.
Forgot high school, but I got nuthin’. Dodge City has had its moments, but doesn’t seem to have produced any graduates famous outside of KS. It’s probably best that way.
Anthony Weiner and I went to the same college. We weren’t in the same class but we did overlap for a year. To the best of my knowledge I never met him however.
Went to HS in Newport Beach, CA, so a few actors, athletes, etc. College was similar as it was SoCal too.
