Larry Silverstein and Albert Bourla built their careers in different industries. Silverstein founded a major real estate company and became a central figure in rebuilding the World Trade Center. Bourla trained as a veterinarian before rising through Pfizer to become its chairman and chief executive officer.
Their names also appear together in articles about business leadership, but the connection needs careful explanation. A documented overlap involves a 2022 America-Israel Friendship League awards program honoring Bourla and executives from Silverstein’s company. That event does not establish a personal partnership or family relationship between the two men.
Their individual biographies tell much broader stories, stretching from Brooklyn and Thessaloniki to positions of substantial influence in American business.

What Connects Larry Silverstein and Albert Bourla?
The clearest documented institutional connection comes from the America-Israel Friendship League’s 2022 gala.
According to the organization’s announcement, Pfizer and Bourla received the Kenneth J. Bialkin Leadership Award. Teva Pharmaceuticals and its then-CEO, Kåre Schultz, also received that award.
The Partners for Democracy Award went to Danna Azrieli and two Silverstein Properties leaders: Lisa Silverstein and Tal Kerret. Lisa is Larry Silverstein’s daughter.
This distinction matters. The announcement names Lisa Silverstein and Kerret as honorees, rather than Larry Silverstein personally. It places Bourla and Silverstein Properties within the same awards program, but it does not demonstrate that Bourla and Larry jointly operated a business.
The reliable records reviewed for this biography do not establish a family relationship or direct business partnership between them. Their shared presence in discussions of New York business, Jewish heritage, and philanthropy should therefore remain separate from claims of a closer connection.
Larry Silverstein’s Brooklyn Childhood and Legal Education
Larry A. Silverstein was born in Brooklyn on May 30, 1931, and grew up in a Jewish family. His father, Harry G. Silverstein, worked in real estate, giving him an early introduction to the business that would shape his adult life.
In a recollection published by Brooklyn Law School, Silverstein described listening to family discussions about properties in Lower Manhattan. Much of that activity centered on the manufacturing and industrial neighborhood now known as SoHo.
He also developed an interest in classical music and played the piano. Before entering the property business full time, he attended New York’s High School of Music and Art and graduated from New York University in 1952.
His legal education deserves particular attention because some biographical summaries describe it incompletely. Brooklyn Law School identifies Silverstein as a 1955 graduate, rather than simply someone who attended classes.
Silverstein explained that he studied law in the morning and worked in his father’s office during the afternoon. Although he never practiced law, he credited that training with helping him understand negotiations, contracts, and the legal consequences of business decisions.
Building Silverstein Properties and Rebuilding the World Trade Center
Silverstein entered real estate through the family business. In 1957, he established the enterprise that became Silverstein Properties with his father and his brother-in-law, Bernard Mendik.
After Harry Silverstein died in 1966, the younger partners continued the company. Larry and Mendik eventually separated their business interests in 1977.
Over the following decades, Silverstein expanded his involvement in Manhattan office buildings and development. His connection to the World Trade Center began before the transaction that later made him internationally recognizable: he developed the original 7 World Trade Center during the 1980s.
The 2001 lease and its aftermath
In July 2001, Silverstein signed a 99-year lease for the World Trade Center in a transaction valued at approximately $3.2 billion. The Port Authority remained the underlying owner; the agreement gave his group long-term leasehold interests.
The September 11 terrorist attacks destroyed the Twin Towers and other buildings in the complex only weeks later.
Reconstruction became the defining undertaking of Silverstein’s career. It required negotiations among public authorities, insurers, architects, lenders, and prospective tenants, alongside intense public debate about how the site should commemorate the victims.
Insurance disputes added years of difficulty. Silverstein Properties and the Port Authority ultimately received approximately $4.55 billion in insurance proceeds. Those proceeds concerned the destroyed property and redevelopment obligations; they should not be described as Silverstein’s personal earnings.
The rebuilt 7 World Trade Center opened in May 2006. His company subsequently opened 4 World Trade Center in 2013 and continued its involvement in the wider redevelopment.
Silverstein’s role was substantial, but rebuilding the site was a collective undertaking involving numerous public institutions, companies, designers, and construction teams.
Larry Silverstein’s Marriage, Children, and Public Contributions
Silverstein met his future wife, Klara, while working at a summer camp during his college years. They married on July 1, 1956.
The couple have three children: Sharon, Lisa, and Roger. Several family members have worked in the real estate business, making the company a multigenerational enterprise.
Silverstein Properties marked Larry and Klara’s 70th wedding anniversary in July 2026. Its family profile also records eight grandchildren and one great-grandchild.
Their public contributions extend beyond property development. They have supported education, medical research, humanitarian causes, and the arts.
POLIN Museum of the History of Polish Jews identifies the couple as distinguished benefactors who joined that group in January 2013. Silverstein has also held longstanding leadership and advisory roles connected with New York University and real estate education.
His memoir, The Rising, appeared in 2024 and recounts the prolonged effort to rebuild the World Trade Center. In March 2026, Brooklyn Law School recognized him as its Alumnus of the Year.

Albert Bourla’s Early Life in Thessaloniki
Albert Bourla was born on October 21, 1961, in Thessaloniki, Greece. He grew up in the city’s Jewish community, with Sephardic family roots.
His parents, Mois and Sara, survived the Holocaust. Their experiences belonged to a devastating chapter in Thessaloniki’s history, when Nazi persecution nearly destroyed the city’s Jewish population.
In accounts of his family history, Bourla has described his father surviving through concealment and his mother narrowly escaping execution. These are his parents’ wartime experiences; Bourla himself was born years after World War II.
Speaking to the Posse Foundation, he described a household with limited resources but enough to meet the family’s needs. He associated his mother with determination and his father with caution and careful consideration.
Bourla studied veterinary medicine at Aristotle University of Thessaloniki. He earned a Doctor of Veterinary Medicine degree and a doctorate in the biotechnology of reproduction.
His qualifications established a scientific foundation for his career. He trained as a veterinarian, rather than as a physician treating human patients.
From Pfizer’s Animal Health Business to Chief Executive
Bourla joined Pfizer in 1993. His early career included animal health responsibilities, followed by increasingly broad international management positions.
His progression took him across different countries and business divisions. Between 2010 and 2013, he led Pfizer’s Established Products business, which included medicines facing the commercial challenges associated with lost patent protection.
He later oversaw vaccines, oncology, and consumer healthcare. By 2016, he was leading Pfizer Innovative Health, with responsibilities spanning several major therapeutic areas.
Pfizer appointed him chief operating officer effective January 2018. He became CEO in January 2019 and chairman in January 2020.
These appointments followed more than two decades within the company. Bourla did not found Pfizer; he rose through an established multinational organization.
Leadership during the pandemic
The COVID-19 pandemic brought extraordinary public attention to his role. Under Bourla, Pfizer partnered with Germany’s BioNTech to develop and commercialize an mRNA vaccine.
Bourla’s contribution centered on executive leadership, resource allocation, manufacturing commitments, and commercial decisions. The scientific achievement belonged to teams across the collaborating organizations, alongside clinical investigators and trial participants.
The pandemic also brought scrutiny of pharmaceutical pricing, access, corporate profits, and executive compensation. His later leadership has included the challenge of developing Pfizer’s business beyond its pandemic-era products.
Albert Bourla’s Family, Citizenship, and Recognition
Bourla is married to Myriam, and they have two children. Public profiles identify the family with New York, although his international career involved numerous relocations.
His Greek birthplace, Jewish heritage, and American citizenship describe different aspects of his background. Carnegie’s Great Immigrants profile records that he became a U.S. citizen and has spoken appreciatively about opportunities in America.
In 2022, Bourla received the Genesis Prize for his leadership during the vaccine effort. He asked the foundation to direct the $1 million award toward establishing a Holocaust museum in Thessaloniki.
That decision connected his international recognition with the history of his hometown and his parents’ survival.
His other documented honors include the Golden Cross of the Order of the Redeemer and the Bower Award for Business Leadership. His institutional responsibilities also include chairing the Pfizer Foundation.
Wealth and Their Latest Documented Work
Silverstein’s wealth primarily comes from real estate ownership, development, and investment. Forbes estimated his net worth at approximately $1 billion as of October 30, 2026.
That is an estimate of personal wealth, not the value of every property his company has developed or managed. Large development costs, company assets, and insurance proceeds cannot simply be added together as personal net worth.
Bourla’s finances are more clearly documented through executive compensation disclosures. Pfizer’s 2026 proxy statement reports $27,585,301 in total compensation for 2025, including a $1.8 million salary.
The total includes equity awards and other compensation components. It is neither an all-cash salary nor a verified estimate of his net worth. The records reviewed do not establish a reliable comprehensive personal net-worth figure for him.
As of November 2026, official company profiles continue to identify Silverstein as founder and chairman of Silverstein Properties and Bourla as Pfizer’s chairman and CEO.
Pfizer’s current account of Bourla’s work emphasizes cancer treatments, its 2023 acquisition of Seagen, its expansion into obesity and metabolic disease following the 2025 acquisition of Metsera, and the use of artificial intelligence in medicine development.
Silverstein’s recent documented milestones include his 2024 memoir and 2026 law school honor. His career now spans the growth of a family property business into decades of development and reconstruction.
Read together, their biographies show two distinct forms of business responsibility: financing and rebuilding physical places, and directing an organization that develops medicines. Understanding those separate histories—and the precise limits of their documented connection—offers a clearer picture than treating their names as evidence of a shared enterprise.
