To celebrate the beginning of our 20th year, we’ve set out to catalogue the contributions that Pittsburgh and western Pennsylvania have made to the world. The list has grown and grown, and despite our best efforts, we know we’ll leave out key contributors. I think you’ll find that this small city at the confluence of three rivers has played an astonishingly outsized role in the creation of this country and the world we inhabit. So, read on, and be inspired to pick up the gauntlet and take your turn in building this great American city – Douglas Heuck
Rosie the Riveter – We Can Do It!
Rosie was a cultural icon representing women in the workforce during World War II. J. Howard Miller depicted Rosie flexing her biceps on a poster with the title “We Can Do It!” that he created in 1942 for Westinghouse Electric. As factories shifted to wartime production, women took on roles traditionally held by men, including work in steel mills and munitions plants. In Pittsburgh, women were vital to the city’s contribution to the war effort, embodying the resilience and adaptability symbolized by Rosie.

The Donora Smog Inversion of 1948 and the Clean Air Act
Pittsburgh set the stage for the Clean Air Act during the mid-20th century, when the city was infamous for its severe air pollution caused by industrial emissions, particularly from steel mills and coal-burning plants. By the 1940s, the smog and soot were so dense that streetlights were needed during the day, and residents faced significant health risks. This dire situation spurred local leaders and citizens to demand change.
In 1946, Pittsburgh enacted the nation’s first comprehensive air pollution control legislation, the Smoke Control Ordinance, which introduced measures to reduce emissions, including requirements for cleaner-burning fuels. These efforts served as a model for other cities and demonstrated the feasibility of addressing air pollution through coordinated regulation and public support.
The Donora Smog Inversion of 1948 was one of the worst air pollution disasters in history, occurring in the industrial town of Donora along the Monongahela River near Pittsburgh. For five days in late October, a temperature inversion trapped pollutants from local steel and zinc plants, creating a toxic smog that blanketed the town. The smog was so bad that the crowd in the bleachers at the high school football game couldn’t see the players. Yet, the local populace was so inured to pollution that when ambulances arrived from Pittsburgh with people wearing gas masks, many residents denied there was a problem. The smog killed 20 people and caused respiratory distress in as many as 6,000 others.
The Donora incident gained international attention, sparking public outcry and scientific investigation into the health impacts of air pollution. It served as a wake-up call for policymakers and became a catalyst for the clean air movement. Today, the Donora Smog Museum commemorates the event’s role in shaping environmental awareness and policy, which led directly to the landmark federal Clean Air Act of 1970.
Dr. Jonas Salk – Saved the World from Polio
Dr. Jonas Salk, a researcher and physician based in Pittsburgh, achieved one of the most significant medical breakthroughs of the 20th century by developing the first effective polio vaccine. In the early 1950s, polio was a devastating disease, causing paralysis and death, particularly in children. Working at the University of Pittsburgh, Salk began researching the virus and sought a way to prevent its spread. His work focused on developing a vaccine using an inactivated form of the virus that could stimulate immunity without causing the disease.
In 1953, Salk announced successful preliminary results, which led to a massive clinical trial in 1954 involving nearly 2 million children, known as the “Polio Pioneers.” The trial, one of the largest in history, demonstrated the vaccine’s safety and efficacy. On April 12, 1955, the results were made public and the vaccine was hailed as a monumental success. Salk became a national hero for his role in eradicating a once-dreaded disease.
Unlike many scientists, Salk chose not to patent the vaccine, famously stating, “Could you patent the sun?” His altruistic decision ensured the vaccine’s widespread availability, saving millions of lives worldwide. The rollout of the vaccine was rapid, and within a few years, polio cases in the U.S. had dropped dramatically, marking the beginning of the disease’s eradication in many parts of the world.
The National Foundation for Infantile Paralysis, led by President Franklin D. Roosevelt, played a crucial role in funding the research, showcasing the power of community-driven initiatives, most notably in creating the March of Dimes campaign, a national model for decades.
Salk ultimately left Pittsburgh when then-University of Pittsburgh chancellor Edward Litchfield put up too many obstacles to Salk’s next goal. He built that goal in LaJolla, California, where the Salk Institute became a major economic generator in the biotech industry. The Institute’s building is one of the world’s great pieces of architecture, designed by Louis Kahn.
