You're thinking of Willie Robertson, from the A&E reality TV series Duck Dynasty; Robertson is the CEO of Duck Commander, however it wasn't Harvard University, it was Harding University in Searcy, Arkansas.
In fact not only did Willie go to Harding, his wife Korie Robertson went there as well. Both Willie and Korie returned to Arkansas in November 2012 to speak at the Benson Auditorium on Harding University's campus.
Willie was the one that graduated with a degree in business, and that helped him take the Duck Commander company from a "living room operation" to a million dollar business.
Of interest, Phil Robertson attended Louisiana Tech University in the ’60s, playing football ahead of Terry Bradshaw.
Now in season three, Willie just recently told Parade magazine that so many orders came into the Duck Commander business during the first season that he had to hire forty more employees to handle the volume!
