place in Wiltshire, Middle English Salesbury, Old English Searobyrg, Searesbyrig, Roman Sorbiodoni, Sorvioduni. The first element is a British Celtic word of uncertain sense; the second is *dunon "a hill, fort" or else Gaulish *duro- "fort, walled town." The first element was altered in Old English by folk etymology and the second replaced by its native translation, burh.
Salisbury steak (1885) is named for J.H. Salisbury (1823-1905), U.S. physician and food specialist, who promoted it.
In the Philadelphia Medical Reporter for January 10th, Dr. Hepburn describes the way in which the steak is prepared in the "Salisbury" treatment, which has acquired a great reputation in America for disordered digestion, and widely different diseases of a chronic kind, few drugs being employed simultaneously, and those chiefly of a tonic kind. The best slices of a round of beef are chopped off with dull knives, the object being rather to pound than to cut the meat. [from a report reprinted in several U.S. and British medical journals in 1885 that goes on to describe the method; this version from Homeopathic World, Aug. 1, 1885]
Incorrect use for "hamburger" generally traces to World War I and the deliberate attempt to purify American English of German loan words.
"black man," 1838, American English, originally the name of a black minstrel character in a popular song-and-dance act by T.D. Rice (1808-1860) that debuted 1828 and attained national popularity by 1832:
Wheel about, an' turn about, an' do jis so;
Eb'ry time I wheel about, I jump Jim Crow.
Where and how Rice got it, or wrote it, is a mystery. Even before that, crow (n.) had been a derogatory term for a black man. As an adjective from 1833, in reference to the song. Association with segregation dates from 1841, in reference to separate railroad cars for blacks in Massachusetts. Modern use as a type of racial discrimination is from 1943. Jim Crow also could be a reference to someone's change of (political) principles (1837, from the "jump" in the song) or reversible machinery (1875, "wheel about").
On his arrival in Boston, Mr. [Charles Lenox] R[emond] went to the Eastern rail-road depot, in order to visit his parents in Salem; but, instead of being allowed to ride with other passengers, he was compelled to take a seat in what is contemptuously called the "Jim Crow car," as though he were a leper or a wild animal!
