The fourth richest woman in the U.S., according to the Bloomberg Billionaires Index, never even made the list of the richest individuals until this week. Elaine Tettemer Marshall, 70, is the daughter-in-law of the deceased business magnate J. Howard Marshall. Incidentally, that also makes her the daughter-in-law of the infamous Playboy model Anna Nicole Smith, who married J. Howard Marshall in 1994 when he was 89 and she was 26. He died a year later.
Smith died in 2007 from a prescription drug overdose after unsuccessfully fighting a legal battle to win an inheritance from her late husband's estate. You begin to get an idea of why Elaine Marshall and her husband Pierce, heir to the Marshall fortune, kept a low profile.
Elaine Marshall inherited $12.7 billion following the death of her husband in 2006. Her wealth comes from a 15 percent stake in Koch Industries, the second-largest closely held company in the U.S., according to Bloomberg. She shows up at No. 69 on the list of 100 billionaires; the fourth richest woman after the two heiresses to the Wal-Mart fortune, Alice and Christy Walton, and Jacqueline Mars, beneficiary of the Mars candy company.
Bloomberg told ABC News that they uncovered Elaine Marshall's wealth when they took a deeper look into the identity of the minority owner of Koch Industries. As for Marshall, she is sticking to a low profile and not making any public announcements.
