Professor Joseph Schüngel (1844-1922) was a teacher of mathematics and physics at the Rijks HBS in 's-Hertogenbosch and director of that school from 1906-1913. He also taught at the Stedelijk Gymnasium in that town. He is known for his textbooks on physics, which were also used at the Gemeentelijke HBS in Maastricht. Several editions from his textbooks are part of Maastricht University’s Special Collections, such as Leidraad bij het onderwijs in de natuurkunde. Schüngel’s books are scarce in the Netherlands. Maastricht scientist and winner of the Nobel Prize in Chemistry Peter Debye (1884-1966) gained his first knowledge of physics from Schüngel’s books.
