"Heinrich Kley (15 April 1863 in Karlsruhe – 1945 in Munich) was a German illustrator, editorial illustrator and painter.
Kley studied "practical arts" at the Karlsruhe Akademie and finished his studies in Munich. His early works were conventional portraits, landscapes, still lifes, city scenes and historical paintings. From about 1892 he won a reputation as an "industry artist", painting manufacturing scenes in oils and watercolors. They proved his deep understanding of the modern machine world. Kley attained greater notoriety with his sometimes darkly humorous pen drawings, published in Jugend and the notorious Simplicissimus." - (en.wikipedia.org 28.01.2022)
