Jonas Salk Biography


Before the introduction of a vaccine, epidemic outbreaks of polio, a disease that primarily affected children, often resulted in thousands being paralyzed, with many succumbing to the disease due to respiratory failure. In one of the worst years, 1952 saw 60,000 children infected, thousands paralyzed, and over 3,000 passed away.

Each summer, when outbreaks were most common, uncertainty and fear loomed large. Cities would close public pools, theaters, and other gathering places to curb its spread. The specter of children in iron lungs, devices designed to help polio victims breathe, became haunting symbols of the disease’s devastating impact. 

Dr. Jonas Salk, a groundbreaking medical researcher, forever changed lives and the course of medical history by developing the first effective polio vaccine. The vaccine transformed this feared global epidemic into a preventable disease. 

Early Years

Born in New York City on October 28, 1914, Jonas grew up in a working-class neighborhood as the eldest of three sons. His parents, Daniel and Dora Salk, were Russian-Jewish immigrants, who, like many of their contemporaries, sought a better life in America. They valued education deeply and instilled this belief in their children. And despite the family’s economic challenges, his parents were determined to provide their children with every possible educational opportunity.

From an early age, Jonas exhibited an aptitude for academia. His keen mind and diligent work ethic were evident throughout his schooling. As a young student, he attended the local public schools, where his dedication and passion for learning became increasingly evident. In the words of a classmate, Jonas “was known as a perfectionist…who read everything he could lay his hands on.” 

But in those school years, Jonas did not display any particular interest in science or medicine. In his words, upon reflecting,

“As a child I was not interested in science. I was merely interested in things human, the human side of nature, if you like, and I continue to be interested in that.”

After excelling in his early education, Jonas pursued undergraduate studies at City College of New York. A free public college known for its rigorous academic programs, City College was an ideal fit for the ambitious young man. 

Upon completing his undergraduate degree, Jonas was admitted to the New York University School of Medicine. This was a significant achievement, given the competitive nature of medical school admissions. At NYU, his experiences and interactions with faculty members and peers deepened his commitment to pursuing research to have a broader impact on public health.

With his medical degree, Jonas began his professional journey as an intern at Mount Sinai Hospital in New York. This initial foray into hands-on medicine offered him invaluable insights, but Jonas’s true passion remained in research. Recognizing this calling, he soon transitioned from direct patient care to a more research-oriented path.

During that time, the world was in turmoil as World War II raged, bringing many medical challenges. One such challenge was influenza. Working alongside Dr. Thomas Francis, a renowned virologist, Jonas gained critical experience in vaccine development and helped develop a vaccine that was used at U.S. army bases.

In 1947, Jonas was offered a lab at the University of Pittsburgh School of Medicine. There, with financial support from the National Foundation for Infantile Paralysis, Jonas began focusing on polio. Unlike many of his contemporaries experimenting with live-virus vaccines, Jonas believed in a different approach. He championed the idea of using a “killed” or inactivated virus, which, if successful, could provide immunity without the risk of causing the disease.

By 1954, after intensive research and development, Jonas and his team launched the first large-scale polio vaccine trial. “When you inoculate children with a polio vaccine, you don’t sleep well for two or three months,” Jonas would comment about some of his feelings during the trials. 

The following year brought a momentous announcement: the vaccine was deemed safe and effective. On April 12 came the announcement. “Safe, effective, and potent.” On April 13 came the first vaccines. Jonas Salk became a celebrated figure worldwide. Yet, with characteristic humility, he declined to patent the vaccine. When a reporter asked Jonas who owned the patent to the vaccine, he famously replied, “Well, the people, I would say. There is no patent. Could you patent the sun?”

Later Years

Jonas continued working for many more years. His insatiable curiosity and commitment to improving human health propelled him into further research, leading to the establishment of the Salk Institute for Biological Studies in La Jolla, California, in 1963. This research facility would become a hub for scientific exploration, fostering innovative studies in various fields of biology and medicine. Jonas passed away in La Jolla, California, in 1995.
