In celebration of Polish American Heritage Month, we recognize the economic, cultural, political, and social contributions of notable immigrants and refugees who’ve helped shape America’s vibrant tapestry. Today, we spotlight world-renowned Polish American, Nobel Prize-winning scientist, Dr. Israel Rabi.
Israel Isaac Rabi was born in Rymanów, Poland. When he was one year old, his family immigrated to the United States and settled in a small, one-room apartment in Manhattan. As a child, Israel developed a keen interest in science, often visiting his local public library to borrow books. While still in elementary school, he authored his first paper on a radio condenser design, which Modern Electronics Magazine published.
After high school, he attended Cornell University, first to study engineering and later chemistry, graduating in 1919. Rabi returned to Cornell and later transferred to Columbia University, where he earned a Ph.D. in physics, focusing on the magnetic properties of crystals.
After spending two years in Europe, Columbis hired Dr. Rabi as a professor. In 1940, he became Associate Director of the Radiation Laboratory at the Massachusetts Institute of Technology. He later returned to Columbia to head its physics department. During World War II, Rabi helped develop the atomic bomb, then advocated for peace and limiting the use of nuclear weapons.
While Israel’s early work focused on crystals, he later began studying the magnetic properties of atomic nuclei, while building on Dr. Otto Stern’s groundbreaking work on the molecular beam method to enhance its capabilities. His methods and creations enabled him to detect the single states of rotation of atoms and molecules, thereby determining the mechanical and magnetic moments of nuclei. When the beam was exposed to radio waves, the direction of rotation could be changed, but only in certain stages, in accordance with quantum mechanics. When the atoms returned to their original positions, they emitted electromagnetic radiation with uniquely characteristic frequencies.
While his work was foundational to the technology that subsequently led to today’s widely used medical diagnostic technology, Magnetic Resonance Imaging (MRI), in 1940, he was also awarded the Nobel Prize “for his resonance method for recording magnetic properties of atomic nuclei.”
Dr. Rabi held an honorary Doctor of Science from Harvard and Birmingham Universities. He was a fellow of the American Physical Society and a member of the National Academy of Sciences, the American Philosophical Society, and the American Academy of Arts and Sciences. In 1988, he died of cancer in his Manhattan home.
