The Old Man is gone.

Richard Harrison, fondly known as "The Old Man" on History's "Pawn Stars," died Monday morning. His son Rick Harrison shared the sad news with TMZ. There was no mention of the cause of death. He was 77.

The Old Man was Rick's father, Corey's grandfather, and co-founder/co-owner of the Gold & Silver Pawn Shop in Las Vegas. He was a 20-year veteran of the U.S. Navy, which he occasionally referenced on the show.

"He was my hero and I was fortunate to get a very cool 'Old Man' as my dad," Rick told TMZ.

Here's the pawn shop's announcement:

"Pawn Stars" premiered in 2009 and became The History Channel's highest-rated show. It has aired 15 seasons and more than 520 episodes to date.

A rep for The History Channel shared a statement with TMZ:

"We are deeply saddened by the loss of our friend Richard 'The Old Man' Harrison, a beloved member of the HISTORY and 'Pawn Stars' family. He will be greatly missed for his wisdom and candor."
