High Quality Content by WIKIPEDIA articles! Karl Rudolph Koenig (German: Rudolf Koenig; November 26, 1832 – October 2, 1901), known by himself and others as Rudolph Koenig, was a German physicist, chiefly concerned with acoustic phenomena. Koenig was born in Konigsberg (Province of Prussia), and studied at the University of Konigsberg in his native town. About 1852 he went to Paris, and became apprentice to the famous violin-maker, Jean Baptiste Vuillaume (1798-1875), and some six years later he started business on his own account. He called himself a "maker of musical instruments," but the instrument for which his name is best known is the tuning fork. Koenig's work speedily gained a high reputation among physicists for accuracy and general excellence. From this business Koenig derived his livelihood for the rest of his life. One of his last catalogs had 262 different items.
