American real estate developer; chairman and owner of the Irvine Company

Donald Bren (born 11 May 1932) is an American property developer, chairman and sole owner of the Irvine Company, which owns about 129 million square feet of property, mostly in Southern California, including more than 590 office buildings and 125 apartment complexes.^[1]^[2] Forbes calls him America's wealthiest real estate baron.^[1] On 10 November 2026 the Forbes Real-Time Billionaires list ranked Donald Bren 137th in the world, with an estimated net worth of US$19.8 billion; Forbes lists the source of wealth as real estate.^[1]^[3] In the annual World's Billionaires list published in 2026, Forbes had ranked Donald Bren 144th, at US$19.2 billion.^[4] Bren joined a group of investors that bought the Irvine Company in 1977, bought out his partners and the Irvine heirs in 1983 after a long legal fight, and became sole owner in the 1990s.^[2]^[5]^[6] He has given more than 57,000 acres of the Irvine Ranch to be kept as open space.^[1] In 2023 Forbes estimated his lifetime giving at US$2.1 billion, but Inside Philanthropy reported in 2026 that his personal giving had slowed sharply.^[7]

Early life and education

Bren grew up in Bel-Air and Beverly Hills. His father, Milton Bren, was a property investor and the Hollywood producer of the "Topper" comedies, and in 1948 his father married the actress Claire Trevor.^[2] Forbes says Bren worked as a carpenter's helper on his father's buildings.^[1] He went to the University of Washington on a skiing scholarship and earned a degree in business and economics. He missed the chance to make the 1956 Olympic team when he broke his ankle.^[1]^[2] He then served as an infantry officer in the United States Marine Corps, leaving as a first lieutenant.^[2]

Early career

After leaving the Marines, Bren borrowed US$10,000 from a friend at a bank and started building homes, beginning with a waterfront plot on Lido Isle in Newport Beach.^[2] The Bren Co. grew quickly. In 1963 he persuaded the O'Neill family to let him build the new town of Mission Viejo, though they later bought him out.^[5] In 1969 he sold the Bren Co. to International Paper for US$35 million and bought it back three years later for US$28 million.^[5]

Irvine Company

In 1977 Bren and other investors bought a controlling interest in the Irvine Company, which owned the 93,000-acre Irvine Ranch, about a fifth of Orange County.^[2]^[8] In the early 1980s he borrowed US$560 million to buy out his partners and then moved to acquire the remaining shares held by members of the Irvine family.^[2] The heiress Joan Irvine Smith sued in 1983, alleging that he had cheated her out of her stock. In 1990 a court referee ruled that Bren should pay her US$149 million plus interest; she had sought US$330 million, and he had offered US$114 million.^[5] The Los Angeles Times later said the dispute ended with Bren paying her US$240 million, less than half what she had sought.^[2] The Los Angeles Times reported that he was sole owner by 1991, while the Orange County Business Journal dates sole ownership to 1996.^[2]^[6] Under Bren the company developed 44,000 acres of the ranch, including the master-planned city of Irvine and Newport Coast.^[9]^[6] Some plans met strong opposition: Laguna Laurel, a scheme for 3,200 homes in a canyon behind Laguna Beach, drew 8,000 protesters in 1989.^[5] The Orange County Business Journal reported in 2026 that the company's holdings included 590 office buildings, 125 apartment communities with 65,000 units, 40 retail centres, a coastal resort, three golf courses and five marinas, with about 35 per cent of the portfolio outside Orange County.^[6] Forbes reports that the company became sole owner of the MetLife Building in Manhattan when it bought the last 2.7 per cent stake in July 2024.^[1] Succession. In 2011 Bren told the Los Angeles Times that the Irvine Company would continue as a private company controlled by its independent board, which would choose a new chairman, and that "this is a private company that is set up to operate in perpetuity". He said the beneficiaries would be a combination of public and private entities, which he declined to name. The board then included Rick Caruso, Peter Ueberroth and former governor Pete Wilson.^[2]

Wealth

Forbes lists his source of wealth as real estate and classes him as self-made.^[1] In 1990 the Los Angeles Times noted that his suburban holdings had led to him being called a "horizontal Donald Trump".^[5]

Philanthropy

Land. Bren and the Irvine Company set aside about half of the Irvine Ranch as open space.^[8]^[9] In June 2010 Orange County accepted 20,000 acres from Bren and the company, which increased the county's parkland by more than half. The land is managed by the Irvine Ranch Conservancy, a non-profit set up by the Donald Bren Foundation.^[9] The Orange County Business Journal reports that he pledged US$50 million to the conservancy.^[6] Education. By 2011 he had given away US$1.3 billion, including US$200 million to the University of California.^[2] His gifts include US$20 million for a regional park in Irvine in 2004 and US$20 million for a law school at UC Irvine in 2007, and a US$100 million pledge to Caltech made in 2013 and reported in 2021.^[7] He has funded more than 60 endowed chairs at the University of California, Caltech and the Marine Corps University at Quantico.^[6] Since 2006 the Irvine Company and the Donald Bren Foundation have made a 20-year commitment of nearly US$50 million for arts, music and science teaching in the Irvine Unified School District, paid in instalments such as a US$2 million cheque in April 2025.^[10]^[7] Recent giving. Inside Philanthropy reported in September 2026 that Bren had not put any money into the Donald L. Bren Foundation, which held US$378 million, since 2013. The foundation has no employees listed in its IRS filings and now makes only two or three grants a year, mostly to Caltech. His wife joined its board in 2022. A spokesperson declined to answer the publication's questions.^[7] Bren has sat on the board of the Los Angeles County Museum of Art.^[2]

Political activity

In 2011 the Los Angeles Times reported that Bren and his wife are Republicans and that he describes himself as "a fiscal conservative and social moderate". He backed Pete Wilson's Senate campaign and gave to Meg Whitman's campaign for governor, but has also long supported the Democratic senator Dianne Feinstein.^[2] Pete Wilson later sat on the Irvine Company board.^[2]

Personal life

Bren is married to Brigitte Bren, a lawyer; Inside Philanthropy spells her name Brigette.^[2]^[7] In 2011 the Los Angeles Times reported that the couple lived mostly at a waterfront villa on Harbor Island in Newport Beach, a seven-minute drive from the company's headquarters, and also had a home in West Los Angeles and a ranch at Sun Valley, Idaho.^[2]^[8] The paper reported that he had six children. In 2010 two of them, born to a former girlfriend, sued him for US$130 million in retroactive child support, and the jury found in his favour.^[2] Forbes records seven children.^[1]
