Karl Schwarzschild's investigations of 'out-of-focus photometry' between 1897 and 1899 at Kuffner Observatory in Vienna

Peter Habison, Vienna

Abstract

From 1897 to 1899 Karl Schwarzschild worked at the Kuffner Observatory in Vienna. During these years he developed new measuring techniques in the field of photographic photometry, where he studied particularly the quantitative determination of the departure from the reciprocity law during photographic exposure. This paper concentrates on Schwarzschild's early work in this field and gives an overview of his important Viennese years.
