You probably didn’t realize it, but Robert Leo Hulseman has been partying with you for years…

The Red Solo Cup has been a staple at every kegger, Frat party and tailgate since the 1970’s, when Hulseman crafted the 16oz plastic cup that changed college parties forever.

People reports:

“Hulseman, 84, died December 21. A devoted Christian and family man who was married to his late wife Sheila for nearly 60 years, Hulseman is owed a debt of thanks by virtually every American (and quite a few imbibers overseas) for his now-ubiquitous invention, the red Solo cup.”

Pour one out for Robert Leo Hulseman… Rest in Peace
