International Language and Science Considerations on the Introduction of an International Language into Science

Louis Couturat

1868–1914

A brilliant French thinker who moved easily between logic, mathematics, philosophy, and language, he is best remembered for helping shape the planned language Ido. His work also helped bring symbolic logic and Leibniz studies to a wider audience in the years before the First World War.

Otto Jespersen

1860–1943

A pioneering Danish linguist, he helped reshape the study of English with clear, lively ideas about grammar, language change, and how speech really works. His books made serious language study feel practical and readable for students as well as scholars.

A pioneer of physical chemistry, he helped explain how molten salts behave under electricity and built a career at leading centers in Zurich and Frankfurt. His work made a difficult, highly specialized field clearer and more reliable for the scientists who followed.

Wilhelm Ostwald

1853–1932

A founder of physical chemistry, he helped turn a young science into a modern discipline and later won the 1909 Nobel Prize in Chemistry. His work on catalysis, reaction rates, and chemical equilibria shaped how chemists understand change itself.
