Charles G. Chaddock

Charles Gilbert Chaddock (born November 14, 1861 in Jonesville , Michigan , † July 20, 1936 ) was an American neurologist and psychiatrist .

Life

The son of a doctor studied at the College of Medicine and Surgery at the University of Michigan until 1885 . He then worked in Traverse City at the Northern Michigan Asylum (later Traverse City State Hospital), interrupted by a study visit to Munich in 1888/1889 . In 1892 Chaddock moved to St. Louis , where he became professor of neurology and psychiatry at the Marion Sims-Beaumont College of Medicine and worked at various hospitals. From 1897 to 1899 he stayed in Paris as an assistant to Joseph Babinski , and further trips to France followed. He was also on friendly terms with Santiago Ramón y Cajal .

From 1914 Chaddock withdrew - probably due to increasing hearing loss - from clinical work.

Chaddock was married to Adelaide Gowans MacPherson († 1937) from 1890.

Act

Working at Babinski had aroused Chaddock's interest in pyramidal signs such as the Babinski reflex , which he wanted to use to distinguish between neurological and psychiatric diseases. In 1911 he described the clinical sign later called the Chaddock reflex , a modification of the Babinski reflex , as the “external malleolar sign” . In the following year he described a similar sign ("wrist sign") on the upper extremity.

Chaddock translated various writings by European neurologists and psychiatrists into English. These translations include the writings of Joseph Babinski, Richard von Krafft-Ebings, and Albert von Schrenck-Notzings . As a translator of the work sexual psychopathology von Krafft-Ebing Chaddock led perhaps the term "homosexuality" ( " homosexuality a") in the English language.
