Hanns In der Gand was the pen name of Ladislaus Krupski (25 February 1882 in La Vernaz, France (formerly Savoy) – 24 May 1947 in Zumikon, canton of Zurich) was a Swiss folklorist and collector of traditional and military songs. Born to a Polish father and a German mother, he held citizenship of Schleinikon in the canton of Zurich. He was educated in Lucerne, he studied in Neuchatel and was educated as a singer in Frankfurt am Main and Munich. He worked as an actor at the court of Altenburg, but returned to Switzerland in the First World War.
He was active collecting traditional folk songs and instrumental music in all parts of Switzerland in the interbellum period. His pseudonym suggests a native of Uri, the surname being taken from the name of a character in a novel by Ernst Zahn, Albin Indergand. He used this name in order to more easily gain the confidence of his rural informants from whom he collected the songs. He used to perform the songs he collected, accompanying himself on the lute. During both world wars he was employed as a singer in the Swiss Army.
