VEF, Latvian acronym for Valsts elektrotehniskā fabrika (State Electrotechnical Factory), was a manufacturer of electrical and electronic products in Riga, Latvia. It was founded in 1919. Before World War II, it manufactured a large variety of goods, including Minox — then the world's smallest camera. After the war, it was the leading communication technology producer in the Soviet Union and the largest factory in the Latvian SSR. History VEF was established in April 1919 as The Main Workshops of the Latvian Post and Telegraph Department ( (PTVGD)), where, initially, the five mechanics were the only employees. In 1924 the factory was moved for the first time, and in 1928 moved again to its VEF's current location. The factory buildings were built in late 19th and early 20th century and span a city block. Before World War I the buildings were owned by 1887-established Russian-Baltic factory UNION, established by Heinrich Dettmann. The company was renamed to VEF in 1932. In 1922 PTVGD started to manufacture phones. In 1924 it started producing crystal-detector radios. In 1928 it began producing automatic telephone exchanges. They bought the license from Mix & Genest to produce small volume (for 100, 200, 300 numbers) and large volume (1000, 2000 numbers) switchboards. Telephone exchange in Riga and Latvia's populated places were upgraded with equipment manufactured by PTVGD until 1940. During the 1930s the monthly production of PTVGD included 500 phones and 400 exchanges. By the 1930s the factory produced all electronics that had any market demand - communication devices, phones, light bulbs, cameras, irons, radios, flashlights, as well as photo paper, work-tables, and even airplanes. They also repaired cars. VEF entered the world market in 1936 with the development of the Minox subminiature camera, designed by Walter Zapp (). It was the world's smallest camera at the time. Between 1928 and 1933 VEF also produced a small, inexpensive car. During World War II the factory was looted and several buildings were destroyed by explosions. The factory was repaired after the war and it quickly recovered. During the 1960s VEF produced seven radio receivers and five phones every minute and two out of three phones in Soviet Union were produced by VEF. It also manufactured highly demanded transistor-based radios "Spīdola" and in the 1970s — "VEF". During the Soviet period, VEF specialized in electronics and was a part of Latvia's electronic industry, which supplied the former Soviet Union with
