Tozzoli died Saturday in Myrtle Beach, S.C. His death was announced by the World Trade Centers Association, an organization dedicated to furthering global trade that he founded in 1970 and led for four decades.
As director of World Trade Center Development for the Port Authority in the 1960s, Tozzoli oversaw the design and construction of the 110-story towers that were the world's tallest buildings from their dedication in 1973 until the terrorist attack that felled them.
Tozzoli was credited with bringing Japanese architect Minoru Yamasaki to the project. He also fought for the famous Windows on the World restaurant to be included in the north tower, and it was his idea to use the dirt excavated for the trade center as landfill to build Battery Park City.
Current Port Authority Executive Director Patrick Foye called Tozzoli a groundbreaking pioneer.
"His dedication to the WTC site was instrumental in fostering world trade and economic development as a critical part of the Port Authority's mission to create jobs and stimulate economic activity for the region," Foye said.
Tozzoli joined the Port Authority in 1946 and spent his entire career there except for two years of military service during the Korean War.
Tozzoli was given the task of planning and building the World Trade Center in 1962. He coordinated construction of the massive project and then focused on leasing it.
"It will be a city with a working population of 50,000 and a landmark that will attract 80,000 visitors daily," Tozzoli said in an interview during that time. "The center's 10 million square feet of space will make it larger than Rockefeller Center. And it's going to mean a worldwide selling job on our part to get tenants to occupy it."
Tozzoli retired from the Port Authority in 1986 but maintained an office at the trade center, where the agency was headquartered. He spent three hours trapped in a staircase when terrorists set off a truck bomb in 1993.
Tozzoli was about to enter the Holland Tunnel heading into Manhattan from New Jersey when hijacked planes struck the towers on Sept. 11, 2001. He saw the smoking north tower and then watched in horror as the second plane hit the south tower, destroying the project that had been his life's work.
