Wilhelm Ostwald

Friedrich Wilhelm Ostwald, more commonly known as Wilhelm Ostwald, was an eminent Russian-German chemist and philosopher who was a key figure in the development of physical chemistry as a recognized branch of chemistry. He won the 1909 Nobel Prize for Chemistry for his groundbreaking research on chemical equilibria, chemical reaction velocities and catalysis.

Early Life and Education:

Born of German parents in Riga, Latvia in 1853, Wilhelm Ostwald received his early education at the city’s Realgymnasium, where he studied physics, chemistry, mathematics and natural history, while learning various languages such as French, English, Latin and Russian. His father wanted him to become an engineer but Ostwald had already developed an interest in chemistry.

After entering the Dorpat Landesuniversitiit in 1872, Ostwald studied physics under Arthur von Oettingen and chemistry under Karl Schmidt and Johann Lemberg. He received his Candidat in 1875, after writing an essay on the mass action of water. Oettingen consequently took him in as a helper in the physical laboratory. Ostwald received his master’s degree after analyzing the chemical affinity by physical means. He began to give lectures on physical chemistry at the University, and continued his research on affinity, while refining the scientific methods related to the process.

Ostwald earned a doctorate in 1878 and became Schmidt’s assistant in 1879.

Contributions and Achievements:

Wilhelm Ostwald came back to Riga in 1881 to join the Polytechnicum as the Professor of Chemistry, where he soon became a popular teacher and a creative researcher. He worked on two projects that gained him worldwide acclaim; “Lehrbuch Der Allgemeinen Chemie” and “Zeitschrift für Physikalische Chemie”. His works massively promoted the growing field of physical chemistry.

Ostwald went to Leipzig in 1887, where he assumed the chair of physical chemistry. There he carried out groundbreaking research on catalysis, while promoting the works of Arrhenius and van’t Hoff. He made Leipzig a world center for the study of physical chemistry. Moreover, he extensively studied and made important findings regarding energetics. Ostwald spent almost two decades at Leipzig.

Later Life and Death:

Wilhelm Ostwald went into semi-retirement in 1894, choosing to continue only as a research professor. He started focusing more towards “Naturphilosophie” and kept himself away from research in chemistry. He finally announced full retirement in 1906 and moved to his estate at Grossbothen, in Saxony, where he spent his last years as an independent scholar and freethinker, exploring the fields of energetics, scientific methodology, monism and pacifism and internationalism. He also developed a new physical theory of colors.

In 1909 he won the Nobel Prize in chemistry.

Ostwald died at “Landhans Energie” in 1932, after a short illness. He was 78 years old.
