Paul Marie Oudin (1851–1923) was a French physician and medical researcher. He was born, and later died, in Épinal. He conducted research in the Victorian era medical field of high frequency electrotherapy, the application of radio frequency electric currents to the body, and collaborated with the founder of the field, pioneering physiologist and biophysicist Dr. Jacques Arsene d'Arsonval. In 1893 he modified d'Arsonval's electrotherapy equipment by the addition of a wire coil resonator to produce higher potentials, inventing the Oudin coil. This device, very similar to a Tesla coil, could produce very high voltages from several hundred thousand to a million volts. In use, the brush discharges from a pointed electrode attached to the high voltage terminal of the coil would be played over various parts of the body to treat a variety of medical conditions. The Oudin coil was used in electrotherapy and diathermy through the 1920s.

Karl/Carl Wendling ([ventling]) (10 August 1875, Strasbourg – 27 March 1962, Stuttgart) was a German violinist and musical educator.
He studied in his hometown with Heinrich Schuster and Florián Zajíc, and later in Berlin with Carl Halir and Joseph Joachim. From 1902 on he was concertmaster at the Bayreuth Festival. In 1907 and 1908, he was concertmaster with the Boston Symphony Orchestra under Karl Muck. He had his own string quartet, "The Wendling Quartet". From 1909 on, he was a teacher at the Royal Stuttgart Conservatory, where he became director in 1929.
