Short Summary
Heike Kamerlingh Onnes was a pioneering Dutch physicist renowned for his groundbreaking work in low-temperature physics. He is most famous for his discovery of superconductivity in 1911, a phenomenon where electrical resistance in certain materials completely disappears at very low temperatures. Onnes' meticulous experimentation and innovative techniques in cryogenics significantly advanced the field of physics, earning him the Nobel Prize in Physics in 1913. His work laid the foundation for future scientific and technological developments in superconductor research.
Early Life & Education
Born on September 21, 1853, in Groningen, Netherlands, Heike Kamerlingh Onnes was the eldest son in a family with a strong academic tradition. His father, Harm Kamerlingh Onnes, was a respected brick manufacturer, and his mother was Anna Gerdina Coers. Heike exhibited a keen interest in science from a young age, which led him to pursue studies at the University of Groningen. He later attended the University of Heidelberg, where he studied under notable physicists such as Robert Bunsen and Gustav Kirchhoff. Onnes completed his doctoral studies back at the University of Groningen in 1879, focusing on the theory of elasticity.
Career Highlights
After completing his education, Heike Kamerlingh Onnes joined the University of Leiden in 1882 as a professor of experimental physics.
