The Oppenheimer Family Tree is not just a lineage of business magnates—it’s a story of resilience, innovation, and a commitment to making a difference. Let’s dive into their fascinating journey.


The Oppenheimer Family Tree: From Humble Beginnings to Global Dominance

Explore the Oppenheimer Family Tree, a legacy of diamonds, power, and philanthropy that shaped South Africa and the global diamond industry.
Oppenheimer Family Tree

The Oppenheimer Family Tree begins with Eduard Oppenheimer, a German cigar merchant, and his wife, Nanette Hirschhorn. Their son, Sir Ernest Oppenheimer, would become the architect of the family’s fortune. Born in 1880, Ernest moved to South Africa in his early 20s, where he quickly mastered the diamond trade. By 1917, he was chairman of De Beers, the company that would become the cornerstone of the family’s wealth.

Ernest and his wife, Mary Lina Pollak, had two sons: Harry Frederick Oppenheimer and Frank Oppenheimer. While Harry would go on to become one of the most influential businessmen of the 20th century, Frank’s life was tragically cut short at the age of 24. Despite this loss, the family’s legacy continued to grow under Harry’s leadership.

Harry married Bridget McCall, and they had two children: Mary Oppenheimer and Nicholas (Nicky) Frank Oppenheimer, born on 8 June 1945, was destined to carry forward the family’s legacy. Educated at Harrow School in England and later at Christ Church, Oxford, Nicky earned a Master’s degree in politics, philosophy, and economics. While he famously joked about not working very hard at university—earning a third-class degree—his time at Oxford was formative, shaping his worldview and preparing him for the challenges ahead.

Nicky married Orcillia “Strilli” Lasch in 1968, and the couple had one son, Jonathan Oppenheimer, who would later become the heir to the family empire. Nicky’s leadership marked a new era for the Oppenheimer family, as he modernized the family business and navigated the complexities of a changing global economy.

In 1983, Nicky became the deputy chairman of Anglo American, and by 1998, he was appointed chairman of De Beers. Under his leadership, De Beers evolved from a traditional mining company into a modern, diversified enterprise. Nicky played a pivotal role in establishing the Kimberley Process Certification Scheme, a global initiative to prevent the trade of conflict diamonds.

Despite his immense wealth and influence, Nicky is known for his humility and reserved nature. With a net worth of approximately $9.5 billion, he is one of the richest men in Africa, yet he remains deeply committed to philanthropy and conservation. His passion for the environment is evident in his ownership of over 720 square miles of conservation land across Southern Africa.


The Oppenheimer Family’s Influence in South Africa

The Oppenheimers didn’t just build a business—they shaped a nation. Through De Beers and Anglo American, the family became a driving force in South Africa’s economy. But their influence extended far beyond diamonds.

Harry Oppenheimer, a vocal opponent of apartheid, used his wealth and influence to support anti-apartheid movements. He financed the Progressive Federal Party, which later merged with the Democratic Alliance. His commitment to social justice and economic development earned him respect both locally and internationally.

The family’s philanthropic efforts are equally remarkable. The Oppenheimer Memorial Trust, established by Harry, continues to fund education and research in South Africa. Nicky Oppenheimer, too, has made significant contributions to conservation, owning over 720 square miles of protected land across Southern Africa.


The Oppenheimer Family Net Worth

The Oppenheimer family’s net worth is a testament to their dominance in the diamond and mining industries. At its peak, the family’s fortune was estimated at over $10 billion, making them one of the wealthiest families in Africa.

Much of this wealth was built through De Beers, which controlled up to 90% of the global diamond market at one point. The family also held a significant stake in Anglo American, one of the world’s largest mining companies.

In 2011, the Oppenheimers sold their 40% stake in De Beers for $5.1 billion, marking the end of an era. Despite this, the family remains incredibly wealthy, with Nicky Oppenheimer alone boasting a net worth of approximately $9.5 billion as of recent estimates.


The Oppenheimer Family and South African Presidents

The Oppenheimers have long been influential figures in South African politics, maintaining relationships with several presidents. Harry Oppenheimer was known for his opposition to apartheid and his support for progressive policies. He had a close relationship with Nelson Mandela, who admired Harry’s commitment to social justice and economic equality.

Nicky Oppenheimer also worked closely with Mandela, particularly in promoting ethical practices in the diamond industry. The family’s efforts to establish the Kimberley Process Certification Scheme were supported by Mandela, who recognized the importance of eliminating conflict diamonds.

The Oppenheimers’ influence continues today, with Jonathan Oppenheimer engaging with current leaders on issues like conservation and economic development.


The Heir to the Oppenheimer Family

Today, the Oppenheimer Family Tree is carried forward by Jonathan Oppenheimer, the son of Nicky Oppenheimer. Born in 1969, Jonathan has seamlessly stepped into his role as the family’s torchbearer.

Jonathan Oppenheimer

Jonathan is the executive chairman of Oppenheimer Generations, a family-owned investment firm. He previously served as an executive at De Beers and a vice-president at Anglo American. Like his predecessors, Jonathan is deeply committed to conservation, continuing the family’s tradition of environmental stewardship.

Jonathan was married to Jennifer Ward until her passing in 2017. In 2022, he remarried, though the identity of his new spouse remains private. He is a father of three and continues to uphold the family’s legacy of excellence and responsibility.

The Enduring Legacy

The Oppenheimer Family Tree is more than a lineage of wealth and power—it’s a testament to vision, resilience, and a commitment to making a difference. From Ernest’s pioneering spirit to Harry’s fight against apartheid, and from Nicky’s modernization of the family business to Jonathan’s focus on conservation, the Oppenheimers have left an indelible mark on the world.
