The passing of Maurice Tempelsman at the age of 95 marks the end of an extraordinary life, one that traversed the landscapes of international commerce, high-stakes politics, and deeply private personal relationships. Known to the broader public primarily as the longtime companion of Jacqueline Kennedy Onassis, Tempelsman was a figure of considerable influence, whose biography is as intricate as it is compelling.
A Belgian-born diamond tycoon, Tempelsman cultivated an impressive fortune and wielded significant sway in global markets, particularly in the critical diamond trade from Africa. His life story is not merely a chronicle of personal achievement but also a reflection of the geopolitical shifts of the 20th century, from fleeing Nazi-occupied Europe to becoming a pivotal intermediary in United States strategic material acquisition.
His journey highlights a remarkable blend of entrepreneurial acumen, diplomatic finesse, and a steadfast commitment to his personal relationships, especially with the former First Lady. This detailed account explores the foundational elements of his multifaceted career and the formative experiences that shaped him into the private yet powerfully connected individual he became.
1. **Maurice Tempelsman’s Passing at 95**Maurice Tempelsman, the longtime partner of Jacqueline Kennedy Onassis until her death, passed away on August 23, 2025, at the age of 95. His son, Leon, confirmed to The New York Times that his father’s death, which occurred in Manhattan, was due to complications from a fall. The news marked the conclusion of a life characterized by both immense private achievement and a discreet public presence.
His passing brought to light again the depth of his relationship with Mrs. Onassis, a bond that had captivated public attention in her final years. Despite his prominence in business and politics, Tempelsman remained a remarkably private individual, a trait he shared with the former First Lady.
2. **Early Life and Escape from Nazi-Occupied Europe**Born in Antwerp, Belgium, in August 1929, Maurice Tempelsman’s early life was dramatically shaped by the tumultuous events of World War II. His family, who were Orthodox Jews, was forced to flee Europe in 1940 as Nazi Germany initiated its invasion of Belgium. This harrowing experience undoubtedly instilled in him a resilience and a drive to build a new life.
The Tempelsman family sought refuge and eventually settled in New York City, joining other refugees who had escaped the escalating conflict in Europe. This move from a war-torn continent to the vibrant, growing metropolis of New York laid the groundwork for his future endeavors and provided a new environment for his family to rebuild.
3. **The Genesis of a Diamond Magnate: Education and Early Career**Upon arriving in New York City, Tempelsman pursued higher education, enrolling at New York University. He attended the university for two years, acquiring foundational knowledge before making a pivotal decision that would define his career trajectory. His formal academic pursuits were cut short as he chose to immerse himself in the world of commerce.
He joined his father’s newly established diamond merchant company, Leon Tempelsman & Son. It was within this family enterprise that Tempelsman quickly demonstrated his innate entrepreneurial flair and began his ascent in the diamond industry. This hands-on experience in the diamond trade proved to be far more influential than his brief stint in academia, quickly propelling him towards an internationally recognized position.
4. **Influencing US Strategic Policy through Diamonds**By the early 1950s, while barely in his twenties, Maurice Tempelsman achieved a significant breakthrough that would have lasting implications for both his firm and national policy. He successfully persuaded the United States government to begin purchasing industrial diamonds from Africa. His foresight highlighted the critical importance of these materials.
Furthermore, Tempelsman convinced government officials of the necessity to stockpile these African industrial diamonds as strategic materials, crucial for national emergencies and defense during the Cold War era. This pivotal role transformed him into a vital middleman, facilitating deals between African suppliers and the U.S. government, solidifying his firm’s position in global trade and national security.
5. **Building an Empire: The African Diamond Trade and Beyond**Through his strategic dealings and keen understanding of the global market, Tempelsman rapidly amassed a multi-million-dollar fortune. He became a central figure, acting as the intermediary for years between African diamond suppliers and the United States government. His early entry into newly decolonized nations like Ghana and Zaire (now the Democratic Republic of the Congo) showcased his understanding of emerging opportunities.
He understood that decolonization would loosen colonial control over resources, opening doors for energetic outsiders. His firm, Leon Tempelsman & Son, grew into a diversified company, active in mining, industry, and agriculture. In 1984, he further solidified his empire by becoming the chief executive of Lazare Kaplan International in New York, one of the largest companies specializing in the import, cutting, and sale of diamonds, expanding its reach to include stakes in various mines and major diamond operations across Africa.
6. **Deep Political Engagement and Democratic Party Support**Throughout his life, Maurice Tempelsman maintained close ties with the government and distinguished himself as an ardent supporter of the Democratic Party. From the 1950s onwards, he became one of its most trusted donors and insiders, consistently contributing to its causes and maintaining a prominent role as a fundraiser. His financial contributions were substantial, with approximately $500,000 donated in the 1990s alone.
His dedication to the Democratic Party extended beyond financial support, fostering a vast network of connections within Washington’s most prominent circles. This deep engagement allowed him to cultivate close personal friendships with several influential Democratic leaders, establishing his presence as a respected figure in the political landscape.

7. **An Early Connection to the Kennedy Family**Maurice Tempelsman’s extensive political network provided him with opportunities to forge relationships with some of the most prominent figures in American history. Notably, he developed close personal friendships with several Democratic leaders, including Jacqueline Onassis’s late husband, President John F. Kennedy. Their paths first crossed in the late 1950s, when Kennedy was still a U.S. senator from Massachusetts with presidential aspirations.
Tempelsman, leveraging his formidable reputation in African mining interests and his proximity to leading Democrats like Adlai E. Stevenson II, arranged a gathering for Senator Kennedy with representatives of the South African diamond industry. Later, he played a crucial role in setting up a meeting at the Carlyle Hotel in Manhattan between President-elect Kennedy and Harry Oppenheimer, the chairman of the Anglo American Corporation and of De Beers, further solidifying his early, significant connection to the Kennedy family before his more intimate relationship with Jacqueline blossomed decades later.
Following his early, yet significant, encounters within the Kennedy orbit, Maurice Tempelsman’s life took an even more compelling turn, weaving his formidable business acumen and political gravitas into a profound personal relationship that captivated public attention, all while his complex global dealings continued to shape his legacy. This section examines the evolution of his intimate bond with Jacqueline Kennedy Onassis, his crucial roles as her financial steward and unwavering caregiver, the intricate and at times controversial landscape of his African business ventures, and his later significant philanthropic commitments.

8. **The Evolution of His Relationship with Jacqueline Kennedy Onassis**Although Maurice Tempelsman and Jacqueline Kennedy Onassis had known each other for a significant period—approximately three decades in total—their relationship did not deepen into a romance until the final chapter of her life. Following the passing of her second husband, Greek shipping magnate Aristotle Onassis, in 1975, Tempelsman’s connection with Mrs. Onassis evolved from a professional association into a deeply personal one. By the early 1980s, the pair began making public appearances together, marking the blossoming of their bond.
Those who knew them observed that Tempelsman possessed many qualities that deeply appealed to Mrs. Onassis. He was urbane, reserved, and shared her belief that discretion was a paramount virtue, a characteristic they both exemplified. Their mutual interests extended to a shared love for art, culture, and music, and they often conversed in fluent French during their regular walks through Central Park. These shared intellectual and cultural pursuits formed a rich foundation for their companionship, fostering an environment of mutual respect and understanding.
Tempelsman was also fiercely protective of the former First Lady, a trait that became particularly evident in their public life. He was famously known to shoo away photographers who attempted to capture images of them during their frequent strolls in Central Park. This steadfast commitment to her privacy was widely admired, as Mrs. Onassis herself was revered for the dignity she maintained throughout her life, particularly after the assassination of President Kennedy. There seemed to be an unspoken public consensus that she was entitled to her privacy and personal happiness, a sentiment Tempelsman diligently upheld.

9. **Financial Stewardship and Quadrupling of Fortune**Beyond his role as a devoted companion, Maurice Tempelsman assumed a pivotal position as Jacqueline Kennedy Onassis’s financial adviser after the death of Aristotle Onassis. Her inheritance from the Greek shipping magnate amounted to a substantial $26 million. Under Tempelsman’s astute guidance and strategic financial management, this fortune was reportedly quadrupled, a testament to his unparalleled expertise in the world of high finance and investment.
His stewardship ensured not only the growth of her assets but also their prudent management, reflecting his deep understanding of global markets and his commitment to her financial security. This financial acumen was a significant aspect of their partnership, providing Mrs. Onassis with peace of mind and demonstrating the profound trust she placed in him. His ability to navigate complex financial landscapes brought substantial benefits, allowing her to live comfortably and securely.
Upon her passing in 1994, Tempelsman was further entrusted with her legacy, serving as a co-executor of her will alongside lawyer Alexander Forger. In a poignant gesture, Mrs. Onassis bequeathed to him “my Greek alabaster head of a woman,” a deeply personal item that underscored the depth of their bond and the special place he held in her life. This act symbolized not just their shared aesthetic appreciation but also the quiet, enduring affection that characterized their relationship.
10. **Caregiver in Her Final Years**The depth of Maurice Tempelsman’s commitment to Jacqueline Kennedy Onassis was most profoundly demonstrated during her final illness. In the winter of 1993, after Mrs. Onassis was diagnosed with lymphatic cancer, Tempelsman unequivocally embraced the role of her primary caregiver. This challenging period saw him move his office directly into her Fifth Avenue apartment, allowing him to be constantly by her side, offering unwavering support and practical assistance during her battle with the disease.
He diligently escorted her to and from the hospital for her treatments, providing a steady presence and a comforting hand during a profoundly difficult time. His dedication ensured that she received continuous care and companionship, reflecting a bond that transcended mere romance and evolved into one of profound mutual reliance and devotion. His presence offered immense comfort and stability during a period of great vulnerability.
When Mrs. Onassis succumbed to her illness in May 1994 at the age of 64, Tempelsman was at her bedside. He stood united with her children, Caroline Kennedy Schlossberg and John F. Kennedy Jr., at her funeral at the Church of St. Ignatius Loyola on Park Avenue, and later at her burial in Arlington National Cemetery. During the funeral service, he delivered a moving eulogy, reading from C.P. Cavafy’s poem “Ithaka,” which speaks of life’s journey and discovery. He added his own poignant farewell: “And now the journey is over, too short, alas, too short. It was filled with adventure and wisdom, laughter and love, gallantry and grace. So farewell, farewell.” His steadfast presence and heartfelt words underscored the immense personal loss felt by those close to her and offered a public testament to their deep connection.

11. **The Nuances of His African Engagements: Cold War Politics and Controversies**Maurice Tempelsman’s extensive involvement in the African diamond trade, while establishing his fortune, also entangled him in complex geopolitical dynamics, particularly during the Cold War. His business strategies often extended beyond purely commercial interests, leading to allegations of meddling in African politics to secure favorable conditions for his ventures. This included supporting leaders who were deemed “business-friendly” and aligning with Western interests, sometimes at the expense of nationalist or socialist-leaning governments.
Declassified Kennedy administration documents, as cited by Insight magazine, indicated that Tempelsman’s representatives in Ghana played a leading role in pressing for the removal of the nationalist leader Kwame Nkrumah, whose socialist economic policies threatened the diamond market. Nkrumah was eventually deposed in a 1966 military coup. Similarly, Tempelsman became an early and ardent supporter of Colonel Joseph Mobutu in what became Zaire (now the Democratic Republic of the Congo), and was credited with helping to facilitate Western backing for the autocratic leader. This relationship later paid dividends when Mobutu awarded the copper and cobalt concession at the vast Tenke Fungurume mine to Tempelsman, bypassing a previously promised Belgian group.
These actions, while perhaps seen as politically astute at the time, later drew significant criticism as Mobutu’s leadership grew increasingly corrupt and repressive. One of Tempelsman’s employees in Africa was Lawrence Devlin, a former C.I.A. station chief in pre-Zaire Congo, who continued to pass information to the intelligence agency while working for Tempelsman, further intertwining his business with covert operations. The intersection of mining and political interests in volatile countries made Tempelsman an object of ample curiosity and conspiracy theorizing. He even sued the author and publisher of a book for claiming he was “close to the C.I.A.” In 1984, a French judge ruled the allegation was not defamatory but awarded him a symbolic one franc for invasion of privacy, underscoring the delicate balance between his public influence and intensely private persona.
12. **A Diamond Sightholder and Global Industry Influence**Maurice Tempelsman’s strategic prowess in the diamond industry culminated in his acquisition of Lazare Kaplan International in New York in 1984. This move propelled him to an even higher echelon of global influence, transforming the company into one of the largest specializing in the import, cutting, and sale of diamonds, with prestigious customers including Tiffany’s and Cartier. This acquisition significantly expanded his empire, diversifying Leon Tempelsman & Son into a multifaceted company active in mining, industry, agriculture, and putting together consortiums to mine diamonds and other minerals.
His stature in the global diamond trade was further solidified by his exclusive status as one of only 160 diamond sightholders in the world. This designation placed him within an elite club of individuals and companies privileged to buy rough diamonds directly from the De Beers cartel, which has historically maintained a near-monopoly on the world’s diamond supply. This direct access to the source of global diamond production underscored his unparalleled influence and deep entrenchment in the industry’s most exclusive networks.
Through these vast networks and strategic holdings, Tempelsman not only amassed considerable wealth but also maintained a pivotal role in shaping the trajectory of the international diamond market. His firm held stakes in various mines across Africa and had significant investments in major diamond operations on the continent, affirming his position as a preeminent figure whose decisions resonated across the global gem trade and beyond.
13. **Philanthropic Leadership and African Development Initiatives**Despite the controversies that occasionally shadowed his business dealings in Africa, Maurice Tempelsman also dedicated significant efforts to promoting African development and fostering positive international relations. He chaired influential organizations such as the Africa America Institute and the Corporate Council on Africa, both established with the aim of fostering economic development and strengthening ties between the continent and Western nations. In these roles, he remained at the forefront of Westerners with entrenched personal and business relationships at the pinnacle of African power, whether engaging with right-wing or Marxist governments.
Tempelsman was, at times, a strong supporter of African liberation movements, demonstrating a nuanced approach to the continent’s complex political landscape. A notable instance of his commitment was his financial support for Nelson Mandela’s historic first visit to the United States in 1990, just months after Mandela’s release from 27 years of imprisonment under the apartheid regime. This support highlighted a desire to contribute positively to Africa’s future, balancing his multifaceted history with tangible contributions to its progress.
His work with these institutes and his support for figures like Mandela illustrate a broader commitment to engagement and development. He utilized his extensive networks and deep knowledge of Africa not just for commerce but also for diplomatic and humanitarian ends, seeking to bridge divides and promote understanding between diverse cultures and political systems. This dimension of his work provided a counterpoint to the more contentious aspects of his commercial ventures.

14. **Later Philanthropic Efforts: Combating AIDS in Africa and Jewish Philanthropies**In his later years, Maurice Tempelsman channeled his considerable energy and influence into significant philanthropic endeavors, most notably in the realm of public health. He served as chairman of the international advisory council of the Harvard AIDS Institute, a prominent public health program dedicated to combating the global AIDS epidemic. In this role, he marshaled the extensive networks that had characterized his business career, connecting politicians, scientists, and other stakeholders to strengthen research efforts and intervention strategies aimed at ending the AIDS epidemic in Africa.
Tempelsman believed in the power of collaboration across different sectors to achieve impactful results. As he once told The Times, “The important thing is to mobilize the different parties that can make contributions. Each of them lives in a different universe.” This philosophy underscored his pragmatic approach to philanthropy, focusing on bringing together diverse talents and resources to address complex global challenges effectively. His dedication to this cause reflected a deep concern for the continent that had been so central to his professional life.
Beyond his work in global health, Tempelsman was also actively involved in Jewish philanthropies, reflecting his heritage and commitment to community. His life, which began with the harrowing escape from Nazi-occupied Europe, concluded with a legacy that spanned the intricate worlds of international commerce, strategic politics, and deeply personal relationships. Maurice Tempelsman was a figure of immense complexity and influence, whose impact on global trade, political landscapes, and the lives of those closest to him, including Jacqueline Kennedy Onassis, leaves a distinct and enduring mark on history.
Maurice Tempelsman’s passing marks the end of an era, not just for the global diamond trade but for a unique chapter in American history, intertwined with one of its most iconic figures. His story is a testament to resilience, ambition, and the profound, often quiet, influence one individual can exert across the spheres of business, politics, and personal devotion. He leaves behind a legacy defined by both the scale of his achievements and the depth of his discretion, a true titan whose life reflected the intricate dance of power and privacy on the world stage.
