243536 Mannheim           Discovered 2010 Mar. 15 by E. Schwab at the Tzec Maun Observatory, Moorook.
Mannheim is a German city in the federal state of Baden-Württemberg, where Karl Benz appeared on the streets with his first car in 1886. The Mannheim Observatory, which was in operation from 1772 to 1880, was visited by well-known people, such as Wolfgang Amadeus Mozart and Benjamin Franklin.
