Helmar Lerski (18 February 1871, in Strasbourg – 19 September 1956, in Zürich) was a photographer who laid some of the important foundations of modern photography. His works are on display in the USA, Germany, Israel and Switzerland. He focused mainly on portraits and the technique of photography with mirrors. In 1932, he emigrated with his second wife to Mandate Palestine, where he continued to work as a photographer, cameraman, and film director. On 22 March 1948, they left what was by then Israel and settled again in Zürich.
