Johann Hieronymus Schroter (1745-1816) was a German astronomer who made important observations on the surface features of the moon and the planets. He was the first to describe lunar 'rilles' (cliff-like features on the moon's surface), and his ten year study of the moon resulted in the publication of 'Seleno-Topographische Fragmente' in 1802. His work and his observatory at Lilenthal, near Bremen, were destroyed by Napoleon's army under General Vandamme in 1813.
