The Walton family is among the richest families in the world. Their wealth inherited from Bud and Sam Walton, founders of the world's largest retailer, Walmart.[1] The three most prominent living members (Jim, Rob and Alice) have consistently been in the top ten of the Forbes 400 since 2001, as were John (d. 2005) and Helen (d. 2007) prior to their deaths. Christy Walton took her husband John's place after his death.
