◼ Origin

Elaine Marshall, 84, resides in Dallas, Texas. She and her two sons (Preston Marshall and E. Pierce Marshall Jr.) hold an estimated 16% stake in Koch Inc. (formerly Koch Industries), the $125 billion-revenue conglomerate spanning petroleum refining, chemicals, fertilizers, building materials, and manufacturing. Her interest derives from her late husband E. Pierce Marshall (1939–2006), who was the older son of J. Howard Marshall II (1905–1995), an early Koch Industries partner. J. Howard Marshall II's death triggered one of the most litigated inheritance disputes in U.S. history after he died following his marriage to Playmate Anna Nicole Smith.
