Robert Millikan was born on March 22, 1868, in Morrison, Illinois. He was the son of a Congregational minister and a former college dean. Growing up in a religious and academic household, Millikan developed a strong interest in science from a young age.
Millikan attended high school in Maquoketa, Iowa, where his passion for physics continued to grow. He went on to study at Oberlin College and later received his Ph.D. in physics from Columbia University. After completing his education, Millikan began his career in academia, teaching at various universities before eventually settling at the University of Chicago.
During World War I, Millikan was heavily involved in research related to aeronautics and meteorology, contributing to advancements in military technology. However, it was his work in measuring the charge of the electron that would ultimately earn him the Nobel Prize in Physics in 1923, making him the second American to receive this prestigious award.
One of Millikan's most famous experiments was the oil-drop experiment, which involved suspending small droplets of oil in mid-air using a magnetic field. This groundbreaking research helped to further our understanding of the fundamental properties of atoms and molecules.
Millikan also made significant contributions to the study of cosmic rays, pioneering research into radiation of extraterrestrial origins. His work laid the foundation for future advancements in astrophysics and space exploration.
Outside of his scientific pursuits, Millikan was a devoted family man and a respected member of his community. He passed away on December 19, 1953, leaving behind a lasting legacy in the field of physics.
Robert Millikan's impact on the world of science cannot be overstated. His pioneering research and groundbreaking discoveries have paved the way for future generations of physicists to continue pushing the boundaries of human knowledge.
