One of the most famous radio works in Russia. Founded in 1853 as "Siemens & Halske Telegraph Depot". Best known thru its history as "Kozitsky Works" (Zavod Kozitskogo). By late 1930s was renamed to "Works No. 210". Current official name ZAO "Kozitsky Works", member of "Raduga" Industrial Association.

Founded: 1855
Founded in 1853 as "Siemens & Halske Telegraph Depot". From 1898 part of Association of S&H Works in Russia. From 1919 - "Petrograd Telegraph Works". From March to August, 1922, member of Low Current Factories Trust. From August, 1922, "Petrograd Radioapparatus Kozitsky Works" (Kozitsky was the name of one of Communist Party active members).
By late 1930s the plant was renamed in a military style and has become "Works No. 210". In July, 1941, because of approaching Wehrmacht troops, most part of the plant was moved to Siberua where the same "Works No. 210" name was used in the city of Omsk. Since that time there is "Omsk Kozitsky Devices Works" in existence.
Small part of "Works No. 210" has remained in Leningrad in 1941, and there were some radios produced even though the city was completely blocked by German Wehrmacht troops for 900 days. A well-known example was "Sever" two-way compact radio delivered to the Red Army by airplanes.
In the post-war period there were some military-style designations used to identify Leningrad Kozitsky plant (PO Box 823, PO Box A-1782) but from 1960 it was named "Kozitsky Works" again (in Russian - "Zavod imeni Kozitskogo"), and kept that name ever since.
