Minoru Yamasaki was a prominent American architect. He is best known for designing the original World Trade Center in New York City. He was also a master practitioner of New Formalism. This architectural style emphasized grand shapes and decorative elements.

Throughout his three-decade career, his firm designed over 250 buildings. Yamasaki sought to combine structural strength with aesthetic beauty. His work left a lasting mark on the skylines of many cities.

Building massive skyscrapers requires solving complex engineering problems. For the World Trade Center, Yamasaki faced the challenge of soft soil near New York Harbor. To prevent flooding during excavation, his team used a slurry wall. This involved digging narrow trenches and filling them with a dense mixture of clay and water.

Concrete was then pumped into these trenches to reach the bedrock. This created a watertight concrete bathtub around the site. This method was rare for such a large-scale project in the United States.

Internal efficiency was another major goal for Yamasaki's tall towers. He developed a unique elevator system called a Skylobby. Instead of one large cluster of shafts, he created three separate, connected elevator systems. These systems served different zones of the building based on the floor selected. This innovation saved approximately 70% of the space usually required for traditional elevator shafts. The saved space was then repurposed for additional office areas.

To manage wind, Yamasaki and engineer Fazlur Rahman Khan used an external truss system. Most skyscrapers of that era used internal cross-bracing in the core. Yamasaki’s design used a network of vertical and horizontal structural elements on the exterior. This external support helped keep the lightweight steel and glass structures from swaying. It also reduced the need for large internal support pillars. This design allowed for vast, open office floors unimpeded by columns.

Yamasaki's early career included diverse and sometimes difficult projects. In 1955, he designed the Pruitt–Igoe public housing project in St. Louis. These buildings were stark, modernist concrete structures built on a tight budget. The project faced many problems and was eventually demolished. Some historians consider its destruction a symbolic end to modernist architecture. This period showed the challenges of balancing design with social and economic constraints.

His later work showcased more decorative and personal styles. The Pacific Science Center in Seattle featured iconic, lacy decorative arches.

He also designed the Dhahran International Airport in Saudi Arabia. That terminal was so well received it appeared on a one riyal bank note. Many of his buildings featured narrow vertical windows. This specific style was a personal choice because Yamasaki had a fear of heights. He also frequently used pointed arches inspired by Gothic architecture.

Yamasaki's life was shaped by his early experiences and education. He was born in 1912 to Japanese immigrants in Seattle, Washington. He worked in an Alaskan salmon cannery to pay for his architecture studies. He earned a Bachelor of Architecture from the University of Washington in 1934. He later received a master's degree from New York University. During World War II, he worked at a firm that designed the Empire State Building. He also used his position to help Japanese Americans affected by internment.

His architectural legacy remains a subject of study in the field. While some critics at the time were skeptical of his massive towers, his technical innovations were significant. He designed structures ranging from synagogues to university campuses. His work at Wayne State University incorporated many of his characteristic motifs. These included elevated bases, geometric patterns, and the use of white marble. Even as modernism declined, Yamasaki's influence on large-scale urban design remained evident.
