Die Schwalbe (Germain magazine) write about him:

"The Austrian chess composer Konrad Erlinger (10.02.1856 - 31.12.1944) omitted the last three letters of his name (which is why they do not appear here in bold). He was one of the most important representatives of the old Viennese school, whose often overloaded, ponderous positions no longer quite correspond to today's taste. His three-move move shown here is a good example of the Viennese school, which focussed entirely on mate purity, but does not achieve the elegance of the Bohemian school. "
