Donald Bren is a billionaire in the United States real estate sector. The Irvine Company is the largest private real estate entity in the United States, possessing over 1,022 hectares of commercial and residential properties in California and New York.

Donald Bren was born in 1932 in Los Angeles to a family that combined art and commerce. His father was a film producer, while his mother was a lover of the theater arts. At the age of 10, Bren's parents split. His father subsequently wed an actress, while his mother espoused an affluent businessman. Bren spent his adolescence at Beverly Hills High School, where he and his brother labored as carpenters for their father's real estate development firm each summer. This practical experience cultivated a long-term perspective in him. “Holding real estate for the long term enables the creation of enduring value and provides demonstrable tangible assets,” he stated to the Los Angeles Times in 2011.

Athletic prowess was a significant aspect of Bren's adolescence. He obtained a partial scholarship to the University of Washington for skiing. Donald Bren was seen as a fashionable athlete and was chosen for the 1956 Olympic team, but subsequently could not compete due to an ankle ailment.

In 1955, Bren obtained a degree in Business Administration and Economics. He subsequently served three years in the Marine Corps as a reconnaissance officer, a period that refined his character and discipline.

Established a business utilizing borrowed funds at the age of 25.

In 1958, at 25 years old, Donald Bren undertook a risk by borrowing $10,000 to establish Bren Company and construct his inaugural residence on Lido Island, Newport Beach, California. Subsequently, he persisted in constructing and reselling properties, capitalizing on the real estate surge of the late 1960s.

From 1963 until 1967, he held the position of President of the Mission Viejo Company, a prominent urban development firm. This was the initial action that demonstrated his strategic planning capability.

In 1970, International Paper Company acquired Bren Company for $34 million. However, merely two years later, amidst a slump in the real estate industry, Bren reacquired his company for a mere $22 million—a transaction that exemplified the billionaire's foresight and audacity.

After over two decades of residence and employment in Orange County, Bren is pursuing the most substantial project in the region, Irvine Ranch. This territory encompasses 37,637 hectares, representing 20% of the total county area, and extends approximately 14.5 kilometers along the Pacific shoreline.

In 1977, he and five other shareholders, including the great-granddaughter of real estate magnate James Irvine, acquired the Irvine Company, the proprietor of Irvine Ranch, for $337.4 million. Donald Bren originally possessed one-third of the shares, but by 1983, he had augmented his holding to 86%. By 1996, he acquired sole ownership after investing no less than $80 million to purchase the remaining equity.

For over twenty years, Bren has managed the development of Irvine Ranch, becoming one of the most habitable communities in the nation with his “live-work-play” development strategy. The city is comprehensively interconnected with residential neighborhoods, commercial centers, parks, premier educational institutions, and offices housing almost one-third of the Fortune 500 firms.

The Los Angeles Times stated: "Throughout the years, Donald Bren influenced the design of contemporary suburbia in California and emerged as one of the most emulated urban developers in the United States."

In addition to urban development, Bren has significantly influenced sustainable development. The Irvine Company contributed over fifty percent of Irvine Ranch for enduring conservation, a significant portion of which was declared a National Natural Landmark in 2006.

The Irvine Company presently possesses numerous important real estate assets, including hundreds of office buildings, shopping centers, apartment complexes, hotels, marinas, and golf courses.

Although he is among the wealthiest real estate developers globally, Donald Bren maintains a highly discreet personal life. He is renowned for his charity endeavors. As of 2021, his cumulative philanthropic donations surpassed $1.3 billion.

He has consistently supported K-12 schools, the University of California, as well as initiatives in science, the arts, and conservation. The Donald Bren Foundation has contributed $200 million to education, as stated on its official website.

Compared to other real estate billionaires in the world, what makes Bren stand out is not only the amount of his assets but also the stability and sustainability in the way he developed and managed his properties. Unlike numerous other real estate firms that experience significant volatility owing to market conditions or financial leverage, the Irvine Company, under Bren's stewardship, has sustained stability and achieved consistent growth for decades.
