Named in memory of Louis Zimmer (1888–1970), world-famous Belgian maker of astronomical clocks. Many of his clocks were made for crowned heads and political leaders all over the world. Today he is best remembered for his “wonderclock”, exhibited at the 1939 New York World Fair; his “Jubilee clock”, donated to his native town of Lier in 1930; and his Astronomical Studio. All three masterpieces were housed in or near the “Zimmer Tower”, which has subsequently become one of the main attractions of Lier. (M 11748) _ _.
