Leen Droppert (Vlaardingen, 1930 – Vlaardingen, 2022) studied at the Amsterdam Graphic School and the Academy of Fine Arts in Rotterdam as an evening student. From the mid-1950s he worked as a visual artist and spatial designer, often in Rotterdam and the surrounding area. He is the author of several dozen sculptures in public spaces, including in Rotterdam, Capelle aan den IJssel, Schiedam, Rijswijk, Vlaardingen, Den Briel and Maassluis. In many cases he also designed the surrounding area. In addition to these monumental works, Droppert produced stained glass windows, mosaics and murals and reliefs in churches, schools and other public buildings. His oeuvre also consists of paintings, watercolors, book illustrations, graphics and small sculptures. The Geuzen monument (1983) in memory of the resistance group the Geuzen on the Market in Vlaardingen is his best-known work. In 2020, Museum Vlaardingen organized a retrospective exhibition for his ninetieth birthday and seventy years of artistry.
