Early VLBI in the USSR

history and philosophy of astronomy Œ instrumentation: detectors Œ techniques: interferometric Œ techniques:high angular resolution Œ telescopesThis article gives story of interferometer with independent elements (Very Long Baseline Interferometer) in Russia. Atthe end of February 1962 the author discussed with G.Ya. Gus™kov, DSN Station, Evpatorija a new type of radio inter-ferometer and proposed an experiment between two DSN stations. In September 1962 he reported the new method andproposed a VLBI experiment at seminar of Radio Astronomical Laboratory, Pushino, and then at a seminar of Astronomi-cal Institute GAISH which recommended to take out a Patent. In December GAISH sent documents to the Patent Bureau.In summer 1963 the author discussed with B. Lovell in Evpatorija the VLBI method of and we signed memorandum anEv-JB experiment at =32cm. In December 1963 the Patent Bureau permitted publication, and the paper was sent toRadio˚zika. Really VLBI in the USSR began with the proposal of M. Cohen and K. Kellermann, February 1968, to do anexperiment between 22-m antenna Pushino and 43-m Green Bank.
