James Howard Marshall II was an American billionaire businessman, academic, and government official. He was involved with and invested in the petroleum industry via academic, government and commercial endeavors. He owned 16% of Koch Industries. Marshall was married to model and celebrity Anna Nicole Smith during the last 14 months of his life. His estate became the subject of protracted litigation, which was reviewed by the Supreme Court in Marshall v. Marshall and Stern v. Marshall. The court kept the will and testament intact and substantially all of the assets in Marshall's estate wound up in trusts for the benefit of his daughter-in-law, Elaine Tettemer Marshall, and her family.
