7873 Böll           Discovered 1991 Jan. 15 by F. Borngen at Tautenburg.
Named in honor of Heinrich Böll (1917-1985), outstanding German writer. In his work he described the reality of World War II and the postwar era, mostly through the fate of ordinary people. A democrat with great historical farsightedness, he defended the liberty of the mind whenever it was endangered. In 1971-1974, he was president of the International PEN club. His receipt of the Nobel Prize in literature in 1972 was the visible sign of his appreciation worldwide.
