S. Robson Walton, better known as Rob Walton, is an American businessman and the eldest son of the founder of Walmart, Sam Walton. 

Rob Walton has a net worth of $68 billion. In addition to being a Walton heir, Rob played a central role in the operation of the Walmart business and acted as Chairman from 1992 to 2015.

This sets him apart from his siblings and fellow heirs, as very few of them have ever worked within the business of Walmart. In recent years, Rob has been one of the 15 richest people in the world.

Despite his sensational net worth, Rob Walton lives a very quiet life and rarely gives interviews. Not much is known about his personal life as a result. Many of the other Walton heirs are the same in this regard.

Samuel Robson "Rob" Walton was born on October 28th of 1944 in Tulsa, Oklahoma.

 He is the eldest son of Sam Walton, the founder of Walmart. Rob was raised alongside many other heirs and heiresses of the Walton fortune, including siblings Jim, Alice, and John – the latter of which passed away in 2005.

Rob's father founded Walmart after establishing a number of successful grocery stores across the United States.

Walmart became massively influential during the 80s, and Sam Walton was considered the richest man on the planet at one point. Walmart has since expanded across the globe.
