The Two Women Who Shaped The Oracle Of Omaha: Inside Warren Buffett's Unconventional Marriages With Susan And Astrid
Few billionaire love stories are as unconventional and enduring as that of Warren Buffett, the legendary "Oracle of Omaha." As of late 2025, the world's most famous value investor continues to live a remarkably frugal life in the same Omaha home he bought in 1958, a lifestyle heavily influenced by the two most important women in his life: his first wife, Susan Thompson Buffett, and his current wife, Astrid Menks. Their story is not a simple tale of two marriages but a complex, decades-long arrangement of mutual respect, shared family, and profound philanthropic impact that continues to shape the Buffett legacy today. The most remarkable detail? For years, the three maintained a singular, amicable household, a dynamic that remains one of the most unique in modern business history.
This deep dive explores the lives of Susan and Astrid, detailing their unique roles, their personal biographies, and the lasting influence they’ve had on one of the world's wealthiest men, providing the most current and fresh details on their intertwined lives and the massive philanthropic machinery they helped create.
The Wives of Warren Buffett: A Complete Biography and Timeline
Warren Buffett has been married twice. His marital history is defined by an extraordinary period where his first wife, his long-time companion, and he maintained a unique, loving, and public "threesome" arrangement that lasted until his first wife’s death in 2004.

- Unique Detail: She lived with Warren in his Omaha home from the late 1970s while he was still married to Susan, and the three of them sent out Christmas cards signed "Warren, Susie, and Astrid."
The Unconventional Arrangement: A Trio of Respect and Family
The relationship between Warren, Susan, and Astrid is arguably the most fascinating aspect of the Oracle of Omaha's personal life. It was a dynamic rooted in deep friendship and mutual respect, defying traditional expectations of marriage and separation. This arrangement began in 1977 when Susan Thompson Buffett, feeling unfulfilled in Omaha, decided to move to San Francisco to pursue her dream of becoming a nightclub singer.
Before leaving, Susan introduced Warren to Astrid Menks, a hostess she knew from the local cocktail lounge. Susan explicitly asked Astrid to move in with Warren and look after him, ensuring his well-being. This set the stage for one of the most amicable and unusual relationships in modern history. Warren and Susan never divorced; they remained legally married until Susan’s death in 2004. They continued to speak daily, and Susan even served as a board member for Berkshire Hathaway and was a major shareholder.
The public acknowledgment of this unique trio was perhaps best symbolized by their annual Christmas cards. For decades, the holiday greetings sent from the Buffett household were signed by all three: "Warren, Susie, and Astrid." This unconventional dynamic was a testament to the immense respect and love shared among the three individuals, proving that a family structure can be defined by connection rather than convention. The children—Susan Alice, Howard, and Peter Buffett—also acknowledged and accepted the arrangement, viewing Astrid as a permanent and welcome fixture in their father's life.
Astrid Menks: The Companion of Frugality and Stability in 2025
Astrid Menks, who officially became Mrs. Buffett in 2006, two years after Susan's passing, is the anchor of Warren Buffett’s famously humble life today. Her influence is often seen in the continued emphasis on frugality and practicality that defines the billionaire's image, a stark contrast to the opulence associated with most of the world's wealthiest individuals.
Astrid’s background as a Latvian immigrant and a former waitress instilled in her a sense of thrift that resonated deeply with Buffett's own value investing principles. This shared value system is often highlighted in anecdotes that surface in the media. For instance, a notable story from a recent Sun Valley conference recounted Astrid balking at the idea of paying $4 for a single cup of coffee, noting she could buy a pound of coffee for that price elsewhere. This small, current detail perfectly encapsulates the down-to-earth nature of the couple's life, even as the value of Berkshire Hathaway's stock soars. As of late 2025, Astrid continues to live with Warren in their modest Omaha home, providing the stability and companionship that the nonagenarian investor deeply values. Her presence at the annual Berkshire Hathaway shareholder meetings is a quiet, but constant, fixture.
Susan Buffett's Enduring Legacy: The Power of Philanthropy
While Astrid Menks provides the stability in Warren Buffett's personal life, Susan Thompson Buffett's legacy is the engine behind one of the largest and most influential philanthropic organizations in the United States. The Susan Thompson Buffett Foundation (STBF) is a massive private foundation that has received billions in funding from Warren Buffett.
The foundation’s recent activity underscores its enduring importance. In 2023 alone, the STBF provided over $695 million in grants, making it one of the largest grant-making foundations in the country. Its primary focus areas, which reflect Susan's lifelong passions, are:
- Reproductive Health: The foundation is a major funder of reproductive health care organizations, including those that support pro-abortion initiatives globally, a cause Susan championed.
- Nebraska Scholarships: For over 50 years, the foundation has offered highly competitive scholarships to college students in Nebraska, providing financial aid that has supported thousands of young people in the state.
Susan's death in 2004 was a turning point, not only personally for Warren but also for his philanthropic vision. Her passing led him to commit the vast majority of his wealth to charitable causes, primarily through the STBF and the Bill & Melinda Gates Foundation. The enduring work of the foundation, managed by the Buffett children, ensures that Susan’s social activism and passion for education continue to have a profound, multi-billion-dollar impact on the world, solidifying her status as far more than just the first wife of a billionaire. Her influence on his decision to give away nearly all his wealth cannot be overstated, a crucial piece of the Buffett family narrative that remains highly relevant in 2025.
