American businessman, oil magnate, university professor, attorney, and federal government official. He became a figure of controversy after marrying the voluptuous model Anna Nicole Smith in 1994.
He played soccer and tennis at both the high school and collegiate levels. He graduated from Yale Law School Magna Cum Laude in 1931.
He held a 16 percent stake in Koch Industries, which led to a dispute between him and his eldest son that ended with his son being removed from his estate plan.
His first two marriages lasted 30 years each and his final one to Smith was for just over a year. He had two sons named E. Pierce Marshall and J. Howard Marshall III. His relatives sued each other over complications in his will.
