NET WORTH: $2 billionAGE: 98RESIDENCE: Hancock ParkSOURCE OF WEALTH: InsuranceLAST YEAR: $2 billionCHANGE: 0%THE MONEY: The founder of Mercury General Corp., Joseph saw Mercury’s share price fall roughly 30% between July 2019 and July 2020. The company was hit hard by the Covid-19 pandemic, recording a $140 million loss in the first quarter. In the second quarter, Mercury sent $63 million in auto insurance rebates to customers. The decline in Joseph’s stake was mostly offset by the boost from a cumulative increase in dividend payouts. Joseph, who holds 34% of Mercury’s stock, is by far the company’s largest shareholder. THE BUZZ: Joseph founded Mercury, which specializes in low-cost policies, in 1961 after working as a door-to-door salesman. Last year, the insurer employed 4,400 and wrote more than $3.7 billion in premiums. Joseph is the fourth-oldest billionaire in the world, according to Forbes, and the oldest billionaire in the United States. He was still putting in appearances at Mercury’s Mid-Wilshire headquarters well into his 90s. Joseph was a navigator on a B-17 bomber during World War II and went on to earn a pair of degrees from Harvard University. He and his wife, Vicky, have homes in Hancock Park and Santa Barbara. Their philanthropic causes include USC, Harvard, Cal State Fullerton, Cedars-Sinai and Good Samaritan Hospital.
