Passage: He was a founder of the St. Louis Art Museum and the State Historical Society of Missouri, president of the St. Louis Public Library, and a director of the St. Louis World's Fair (Louisiana Purchase Exposition) of 1904, in which he was host of the Universal Congress of Jurists and Lawyers. He was a bibliophile and he collected rare first editions of Charles Dickens, Robert Burns and others, and artworks of Aubrey Beardsley, George Cruikshank and Thomas Rowlandson. He and industrialist William K. Bixby started the Burns Society; he was twice president of the University Club of St. Louis. He had a remarkable (possibly eidetic) memory—when writer Henry James visited his house, Lehmann could recite whole works that James himself had written but forgotten. For most his life Lehmann was in demand as a public speaker, which he thoroughly enjoyed. His published works included: John Marshall (1901); The Lawyer in American History (1906); Abraham Lincoln (1908); Conservatism in Legal Procedure (1909); Prohibition (1910); and The Law and the Newspaper (1917).

Passage: Four days before the end of the Second World War, undefended Bergen was occupied by the Red Army on 4 May 1945. After the German Democratic Republic (East Germany) was founded, the new government pressed ahead with further industrialization. In 1952, construction began on the industrial area on the town's western outskirts. From 1953 to 1958, the dairy was established, which furnished 300 tonnes of milk daily. In 1955/1956 came the establishment of the VEB Brot- und Backwaren (Bread and Baked Goods). In 1957/1958, the slaughterhouse and meat plant went into production. An efficient food industry was set up in Bergen, supplied from the island and parts of the mainland. Since Reunification and East Germany's accession into the Federal Republic, the town has undergone a number of marked changes. The population dwindled from its former level of almost 20,000 to 16,500. Many prefabricated concrete structures, common in the former Warsaw Pact countries, were modernized and adapted to new demands. In addition, a few schools were closed and new hotels built. Historical downtown was completely renovated and decorated, giving it a new appeal.

answer:
What countries were part of the pact that saw prefabricated concrete structures modernized?
