Biography
Walther Hermann Nernst was a German physical chemist known for his groundbreaking work in thermodynamics and electrochemistry, making him one of the leading scientists of the early 20th century. He was born on June 25, 1864, in Briesen, Prussia (now Wąbrzeźno, Poland), and studied at several top European universities. He took physics and math courses at the University of Zurich, University of Graz, Humboldt-Universität zu Berlin, and University of Würzburg, earning his doctorate in 1887. He achieved habilitation at Leipzig University in 1889, starting his academic journey.
Nernst's key scientific contribution was developing the Nernst heat theorem, which laid the groundwork for the third law of thermodynamics. This theorem says that the entropy of a perfect crystal nears zero as it reaches absolute zero temperature, offering important insights into matter's behavior at extremely low temperatures. This work earned him the Nobel Prize in Chemistry in 1920. He also created the Nernst equation in 1887, detailing the link between electrode potentials and concentrations in electrochemical reactions, making it a vital tool in electrochemistry and physical chemistry.
Throughout his career, Nernst made significant contributions to areas such as solid-state physics and thermodynamics. He held positions at various German universities and was an important figure internationally. His research not only focused on theory but also practical applications, earning him a place in the National Inventors Hall of Fame in 2011, long after his death.
Nernst married Emma Lohmeyer and received numerous prestigious awards, like the Pour le Mérite for Sciences and Arts, the Bunsen Medal in 1914, the Franklin Medal in 1928, and was elected a Foreign Member of the Royal Society in 1932. He also gave the Silliman Memorial Lectures in 1906. Nernst died on November 18, 1941, in Bad Muskau, Germany, leaving a scientific legacy that still impacts modern chemistry and physics.
Before Fame
Nernst grew up during a time of significant scientific progress in Europe, especially in physical chemistry, which was becoming its own field. Born when Dmitri Mendeleev was organizing the periodic table and James Clerk Maxwell was working on electromagnetic theory, Nernst began university in the 1880s as German universities led in scientific research and innovation.
His path through multiple universities was common for ambitious German students then, letting him learn from top scientists and explore different approaches to physics and chemistry. The late 19th century was a time of deep investigation into matter and energy, paving the way for Nernst's later work in thermodynamics and electrochemistry.
