Paul Walden was a Latvian-German chemist. He was born in Rozula parish near Cēsis in Latvia and initially studied at the Riga Polytechnicum and St. Petersburg before receiving his doctorate at the University of Leipzig in 1891 with Wilhelm Ostwald. Walden left Latvia after the Russian Revolution and accepted positions in Germany. The Walden inversion is named after him. Walden also invented ethylammonium nitrate as the first example of an ionic liquid.

Walden left Latvia after the Russian Revolution and accepted positions in Germany. The Walden inversion is named after him. Walden also invented ethylammonium nitrate as the first example of an ionic liquid. Walden is also known for his 1949 book, History of Chemistry, an excellent synthesis of contemporary historical research in the field.
- Paul Walden war ein lettisch-deutscher Chemiker.
- Paul Walden - chemik łotewski i niemiecki . Od 1894 prof. , m. in. politechniki w Rydze, laboratorium chemicznego Petersburskiej Akademii Nauk (również dyrektor od 1911). Po rewolucji październikowej 1917 wyjechał do Niemiec. W latach profesor uniwerstyetu w Rostocku, od 1947 w Tybindze. Od 1910 członek Petersburskiej Akademii Nauk. Najważniejsze prace dotyczyły stereochemii (1895 odkrył zmianę konfiguracji związków organicznych, tzw. inwersja Waldena), elektrochemii, historii chemii. W latach odkrył zależność między przewodnictwem elektrycznych wodnych roztworów soli, a ich ciężarem cząsteczkowym oraz izometrii optycznej.
- Павел Иванович Вальден (Пауль Вальден); 14 июля 1863, Розулская волость, Латвия — 22 января 1957, Гаммертинген, Германия) — латышский химик, профессор Рижского Политехнического института (1894—1918), член Петербургской АН, иностранный почетный член АН СССР. Труды по электрохимии растворов, оптической изомерии (открыл т. н. вальденовское обращение), истории химии.
- Paul Walden, född 1863, död 1957, var en tysk-baltisk kemist. Walden var professor i Riga 1899-1919, i Rostock 1919-1934 och honorärprofessor i Tübingen 1947-1953. Han gav via Emil Fischer upphov till benämningen Walden-omlagring. Walden invaldes 1928 som utländsk ledamot av Kungliga Vetenskapsakademien.
