Larry Silverstein’s Career and Business Success
Larry Silverstein started building his real estate career with his father and later established Silverstein Properties in 1957. Over the years, the company expanded its portfolio through investments in office buildings, residential properties, hotels, and retail developments.
His business approach focused on identifying valuable locations and developing properties that could serve businesses and communities for many years. Through consistent investments, his company became an established name in the American real estate industry.
One of the most significant moments in his career came in July 2001, when he signed a 99-year lease for the World Trade Center complex. The agreement became one of the most discussed real estate transactions in New York’s history.
However, only a few weeks later, the September 11 terrorist attacks destroyed the original World Trade Center buildings. The tragedy changed the direction of his professional life and placed him at the center of an enormous rebuilding effort. <sup>Source: Silverstein Properties and Brooklyn Law School.</sup>
Larry Silverstein and the World Trade Center Rebuilding
The rebuilding of the World Trade Center became the defining project of Larry Silverstein’s career. Following the September 11 attacks, he remained involved in plans to redevelop the site and restore its importance to New York City.
The project required cooperation between government organizations, architects, engineers, construction companies, investors, and other stakeholders. It also involved complex financial arrangements and years of planning.
The new World Trade Center complex introduced modern office buildings, public spaces, transportation facilities, and memorial-related developments. Seven World Trade Center was among the major buildings completed during the rebuilding process.
For Silverstein, the project represented more than another commercial investment. It became a long-term commitment to rebuilding an important part of Manhattan and supporting the area’s economic recovery.
His involvement in the development helped establish his name beyond the traditional real estate industry. Today, his career remains closely associated with the transformation of Lower Manhattan.

Before becoming CEO, Bourla held several senior positions, including Group President of Pfizer’s Innovative Health business and Chief Operating Officer. These roles provided experience in commercial strategy, manufacturing, research, and product development.

Pfizer worked with German biotechnology company BioNTech to develop an mRNA-based COVID-19 vaccine. The collaboration became one of the most important pharmaceutical developments during the pandemic.
The vaccine received its first emergency authorization in December 2020 in the United Kingdom, followed by authorization in the United States. Its development involved extensive scientific research, clinical trials, manufacturing arrangements, and international distribution.
Bourla became a prominent public figure during this period because of his leadership role and frequent communication about vaccine development.
Pfizer also developed Paxlovid, an oral antiviral treatment for eligible patients at risk of severe COVID-19. These developments brought international attention to the company and its research capabilities.
However, the pandemic also created discussions about vaccine access, public trust, pricing, and pharmaceutical responsibilities. These issues remain important parts of the wider conversation about global healthcare.
