Horst Sigmund Rosenthal (10 August 1915 – 11 September 1942) was a German-born cartoonist of Jewish descent.^{[1][lower-alpha 1]} He is best known for his 1942 French comic book Mickey au Camp de Gurs (Mickey Mouse in the Gurs Internment Camp) which he created while he was a prisoner at the Gurs internment camp in France during World War II. He was later transferred to the Auschwitz concentration camp in German-occupied Poland, where he was murdered on arrival.^[4][5]

Rosenthal also created two other French comic books while incarcerated in Gurs, La Journée d'un Hébergé (A Day in the Life of a Camp Resident) and Petit Guide à travers le Camp de Gurs (Little Guide Through the Gurs Camp). The three books were first published in October 2014 by Calmann-Lévy and the Mémorial de la Shoah in Paris, 72 years after they were written.^[4]

Rosenthal was born to Jewish parents in 1915 in Breslau in what was then the German Empire.^{[lower-alpha 2]} With the rise of antisemitism in Germany in the early 1930s, he fled to France on 3 July 1933 after having obtained a visa to stay in Paris for two months. Rosenthal applied for political asylum in November 1933, but it was not until December 1936 that he received it.^[1][4] He worked as a draftsman in Paris until the outbreak of the Second World War. When Hitler invaded France in June 1940, Rosenthal was arrested because of his Jewish ancestry and spent time in four French concentration camps. On 28 October 1940 he was sent to the Gurs internment camp in Pyrénées-Atlantiques in Vichy France.^[1][4] A number of artists, including German-Jewish artist Charlotte Salomon, had also been incarcerated at Gurs.^[4][6]

Camp Gurs was a refugee camp in south west France near the Spanish border, built in 1939 to accommodate refugees fleeing the Spanish Civil War. In 1940 an armistice between Germany and the Vichy government resulted in the conversion of Gurs to a concentration camp to house Jews and other "undesirables".^[7] Living conditions at Gurs were difficult, but the detainees did their best to make life tolerable by engaging in artistic activities when they were able. They held concerts, staged plays and exhibited art created by inmates. Rosenthal, and others, often used humour in their work to cope with the brutal conditions of camp life.^[4][8]

In August 1942, after almost two years at Gurs, Rosenthal was moved to two other camps in France before being transferred to the Auschwitz concentration camp in German-occupied Poland on 11 September 1942. Rosenthal was murdered on the day of his arrival at Auschwitz. He was 27 years old.^[1][4]
