Elaine Tettemer Marshall, 77, has been named the fourth richest woman in America, but has been unknown to billionaire hunters and celeb-watchers until now because of her laid-back lifestyle, despite her father-in-law being the notorious J. Howard Marshall, who married Smith when he was 89 years old and she was just 26.
"She's extremely low-key," Peter Newcomb, editor in charge of the Americas for Bloomberg News's Billionaire Index , told ABCNews.com.
Despite her estimated worth that only puts her behind two Walmart heiresses, Alice and Christy Walton, and candy company beneficiary Jacqueline Mars, Elaine is not flamboyant with her huge fortune, the size of which has come as a great shock to financial experts.
The skill at which Elaine and her late husband, E. Pierce Marshall, have avoided the spotlight is a sharp contrast to the tabloid world that his father was catapulted into when he walked down the aisle with former stripper, Smith.
The source of Marshall's billions is Wichita's Koch Industries, second-largest closely-held company in the U.S., which Pierce Marshall owned 15 percent of, although he tried to downplay his family's mammoth wealth. “Forbes’ calculation of my father’s wealth is a wildly inflated fantasy,” Pierce Marshall claimed in a statement before his death in 2006.
Anna Nicole and Pierce previously viciously battled over the Marshall fortune when her elderly oil tycoon husband died in 1995, but the pinup was eventually beaten out by the legal powerhouse of the Texan tycoons and she not only lost the bitter legal wrangling but also died owing $300,000 in back taxes.
