WALMART heir Rob Walton is part of America's richest family after his father Sam Walton founded the hugely successful retailer.
The first-ever Walmart store opened in July 1962 in Arkansas and would go on to become the world's largest retailer.
Its founder and his wife Helen Walton had four children - Rob, John, Jim, and Alice.
John passed away in 2005 in a plane crash but the three surviving siblings have been consistently listed in the top 20 of the Forbes 400 list since 2001.
According to Forbes, Rob Walton is the 18th richest person in the world and is currently worth $62.6billion.
His younger brother Jim is the 16th richest person with a net worth of $64billion and Alice is worth $61.7billion.

Rob, 78, took over as chairman following his father's death in 1992 but retired in 2015 to pass the role on to his son-in-law Greg Penner.
The Walmart heirs continue to own around 50 percent of the stock collectively.
Rob is a vintage car enthusiast with a collection that includes 12 Ferraris, six Porches, two Maseraties, and a 1963 Corvette Grand Sport Roadster.
The value of the collection is thought to exceed $300million and became ammunition against the former CEO over Walmart employee wages.

Bernie Sanders tweeted in 2021: "If Rob Walton, a key owner of Walmart, can afford an estimated $226 million for an antique car collection that includes 12 Ferraris, 6 Porsches, 2 Maseratis and a 1963 Corvette Grand Sport Roadster, you know what?
"Walmart can afford to pay at least $15/hour to all of its workers."
Rob's home in Paradise Valley, Arizona, outside Scottsdale, has been used as a location for protestors to flock to in order to demand better wages and conditions for Walmart workers.
Last year, the billionaire took his finances in a different direction by agreeing to purchase the Denver Broncos from the estate of Pat Bowlen for $4.65billion.
The Walton-Penner Family Ownership Group was approved for the purchase last summer which makes Walton the richest owner in the NFL.
Also that year, the Walton family took a huge financial hit after Walmart's share price plummeted by 10 percent in 2022.
The fall in shares due to the company's sale of its operations in the UK and Japan and a cut in profit expectations, saw the heirs lose over $27billion.
Rob's parents Sam and Helen set up the Walton Family Foundation in 1987 to honor the 25th anniversary of Walmart.
The philanthropic foundation would focus on family and finding solutions to the world's big problems.
Almost a decade after it was established, the foundation launched its Children's Scholarship Fund in 1998 and gave over $50million a year.

The foundation states that it focuses "on three core objectives: strengthening the connections between K-12 education and lifelong opportunity, protecting rivers, oceans and the communities they support, and advancing our home region of Northwest Arkansas and the Arkansas-Mississippi Delta."
Rob continues to serve as Chair of the Environment Program Committee of the Walton Family Foundation.
