Hendrika Johanna van Leeuwen (July 3, 1887 – February 26, 1974) was a Dutch physicist known for her early contributions to the theory of magnetism. She studied at Leiden University under the guidance of Hendrik Antoon Lorentz, obtaining her doctorate in 1919. Her thesis [1][2] explained why magnetism is an essentially quantum mechanical effect,[3] a result now referred to as the Bohr–Van Leeuwen theorem. (Niels Bohr had arrived at the same conclusion a few years earlier.) She continued to investigate magnetic materials at the "Technische Hogeschool Delft" (now called the Delft University of Technology), first as "assistant" between September 1920 and April 1947, and then she was promoted to "lector in de theoretische en toegepaste natuurkunde" (reader in theoretical and applied physics).[4][5]
Hendrika van Leeuwen was the sister-in-law of Gunnar Nordström, known as the "Einstein of Finland", who studied in Leiden with Paul Ehrenfest, the successor of Lorentz. Her sister Cornelia (Nel) also started a PhD in Leiden, under Willem Hendrik Keesom, but stopped when she married Nordström and moved with him to Helsinki.[5]
Van Leeuwen was present at the celebration of the golden anniversary of the doctorate of Lorentz, on 11 December 1925,[6] and on that occasion reported on the role of Lorentz as scientist and teacher.[7]

Many a great physicist enjoyed being one of Lorentz's students for a shorter or longer period of time. There is no better way to honor our great teacher, than to attempt to continue our own work with all our strengths, enthusiasm and care.
