The Ledger / Robert Bass

Robert Bass

Net worth unknownFinancialsForbes #605US

◼ Origin

Robert Bass (born 1948, Fort Worth, Texas) is the son of Sid Bass and great-nephew of oil wildcatter Sid Richardson, whose Permian Basin fortune passed through two generations to produce one of Texas's largest family fortunes. Robert manages the family's share through Keystone Group LP, a private Austin-based holding company spanning oil and gas, real estate, financial services, and manufacturing. Unlike his brother Lee Bass, Robert operates largely out of public view.

◼ Self-Made Verdict — INHERITED

His fortune derives from the Bass family oil wealth inherited through his father Sid Bass and great-uncle Sid Richardson; he manages, rather than built, the family's capital base.
