credited as the inventor of the Wartenberg wheel.. According to Wartenberg, this device, used to test skin sensitivity, was in widespread use in Europe when he lived in Germany. While he did not invent it, he found it "an indispensable part of the outfit for everyday neurologic practice," and recommended its use to his colleagues in the US. Personal life Wartenberg was born June 19, 1887. In 1929, he married Baroness Isabelle von Sazenhofen. After establishing his career in Germany, he left due to persecution by the Nazi regime and reestablished his career in San Francisco, California, USA. He eventually retired in 1954, to the status of emeritus professor of neurology. Following a period of poor health in his final years, Wartenberg died of a "heart ailment" at Herbert C. Moffitt Hospital on Nov. 16, 1956 at age 69. He was survived by his wife and his father-in-law, Baron Karl von Sazenhofen, with whom he lived.
