Catherine Lozick

Catherine Lozick inherited an estimated 65% stake in Swagelok, a valve-making business her father, Fred Lennon, cofounded in 1947.

Lennon (d. 1998) started Swagelock with a $500 loan; he first appeared on The Forbes 400 list of richest Americans in 1990.

Lennon left his son, John Lennon, a much smaller inheritance ($25 million) than his daughter.

John's son William sued Lozick and her trustees in 2002, exposing the details of the family's finances.

Lozick settled the suit, agreeing to pay each of Lennon's grandchildren an additional $1.25 million.
