Lajos von Horváth, the younger brother of the playwright and writer Ödön von Horváth, worked as an illustrator and caricaturist. Between 1933 and 1937 he worked for the magazines "Jugend" and "Simplicissimus". He created illustrations for François Rabelais' "Gargantua and Pantagruel" (1937), for Jonathan Swift's "Gulliver's Travels" (1947), for Selma Lagerlöf's "The Wonderful Journey of Nils Holgersson with the Wild Geese" (1949) and for his brother Ödön von Horváth's "Sports Fairy Tales". As a wedding present for his friend and former brother-in-law Heiner Emhardt - Lajos von Horváth had married his sister Auguste ("Gustl") Emhardt in 1925 - Lajos von Horváth painted two small boxes, which he and his parents filled with gifts of money for the bride and groom. The Emhardt siblings had already met the Horváth brothers in Munich in 1913 and spent a lot of time with them in Murnau. In 1945, Lajos von Horváth moved to Vienna, where his parents already lived. He also worked as a German teacher for British officers and as a translator from Hungarian. In 1959 he married Elisabeth zu Leiningen-Westerburg. In 2002, the Castle Museum dedicated a special exhibition to Ödön von Horváth's younger and lesser-known brother. Erna Emhardt later created reverse glass paintings, including those with direct reference to the motifs of the Blue Rider. Some of them are in the museum’s reverse glass painting collection.
