Simbrisk is a town East of Moscow. In 1924 it was re-named Ul'ianovsk in honor of Vladimir Lenin whose birth surname was Ul'ianov.
The State Publishing House had its origins in Imperial Russia as the Royal Print Yard in St. Petersburg. As the Red Army controlled more provinces and cities in former Imperial Russia, the State Publishing House developed offices outside St. Petersburg. In 1924, Simbirsk (in western Russia) was renamed Ulyanovsk in honor of Vladimir Lenin (born Ulyanov) who was born in the city.
