Radó, Sándor (Alexander Rado)

Summary

The text comprises a biographical entry on Sándor Radó and part of an entry on railroad maps. Radó (1899–1981) used cartography for news communication and pro-Soviet propaganda, while his European cartographic agencies provided cover for Soviet intelligence work. Summoned to Moscow in 1945 and sent to a Siberian labor camp, he returned to Hungary in 1955 and subsequently led state cartographic activities. He promoted school, national, and regional atlases, served as chief editor of the international 1:2,500,000 world map, and founded Cartactual and Cartinform. Parts of his life, especially after World War II, remain undocumented. The railroad-map entry surveys the diversification of twentieth-century railway cartography. It distinguishes public schematics emphasizing station sequence and transfers, engineering maps requiring accurate surveying, and signaling diagrams preserving track and switch connections. It also describes railway maps displayed on promotional objects, station murals, and relief installations.
