Dachau: town in Bavaria, Germany, from Old High German daha "clay" + ouwa "island," describing its situation on high ground by the Amper River. Infamous as the site of a Nazi concentration camp nearby, opened in 1933 as a detention site for political prisoners and surrendered to the U.S. Army April 29, 1945. Not a death camp per se, but as it was one of the places where inmates from other camps were sent as the Reich collapsed at the end of the war, and as it was one of the few large camps overrun by British or American forces, it has come to symbolize Nazi atrocities in many minds in the West. "Arbeit Macht Frei" was spelled out in metal on the gate (as it was on other concentration camps, such as Gross-Rosen, Sachsenhausen, Theresienstadt).

When the word fell from polite usage, collateral casualties included the enormously popular children's book "The Story of Little Black Sambo" (by Helen Bannerman), which is about an East Indian child, and the Sambo's Restaurant chain, a U.S. pancake-specialty joint originally opened in Santa Barbara, Calif., in 1957 (the name supposedly from a merging of the names of the founders, Sam Battistone and Newell "Bo" Bohnett, but the chain's decor and advertising leaned heavily on the book), which once counted 1,200 units coast-to-coast. Civil rights agitation against it began in 1970s and the chain collapsed, though the original restaurant still is open. Many of the defunct restaurants were taken over by rival Denny's.
