Between 1939 and 1993, Arnold Odermatt (born 1925) documented car accidents in Nidwalden for the Swiss police office. His poignant, unpeopled, sometimes funny and always strange atmospheric photographs call to mind such precedents as Weegee's crime pictures from the 1930s and 40s. They were introduced to the art world when Harald Szeeman exhibited them at the 49th Venice Biennale.
