Wander Johannes de Haas (born March 2, 1878 in Lisse near Leiden , † April 26, 1960 in Bilthoven ) was a Dutch physicist and mathematician .

After giving up his initial plan to become a notary, de Haas studied physics in Leiden. There he became the assistant of Heike Kamerlingh Onnes and received his doctorate from him in 1912 on the compressibility of hydrogen at and below the boiling point . In 1911 he went to Berlin, where he studied magnetism . As a research assistant at the Physikalisch-Technische Reichsanstalt there, he worked with Albert Einstein , which in 1915 led to the verification of the so-called Einstein-de-Haas effect . After returning to the Netherlands in 1916 he became a foundation curator, in 1917 professor of physics at the Technical University of Delft , in 1922 at the University of Groningen and in 1925 at the University of Leiden . There he succeeded his doctoral supervisor and director of the Kamerlingh Onnes Institute.

With the Russian physicist Lev Wassiljewitsch Schubnikow, who was staying in Leiden as a guest scientist , he discovered the Schubnikow-de-Haas effect in the 1920s .

He was a member of the Royal Netherlands Academy of Sciences (KNAW) and, since 1938, of the Académie des Sciences in Paris.

De Haas was the son-in-law of the physicist Hendrik Lorentz .
