Yefim Gordon is arguably the world's leading Russian aviation researcher. Born in 1950 in Vilnius, Lithuania, he graduated from the Kaunas Polytechnical Institute in 1972 as an engineer/electronics designer. He has been a resident of Moscow since 1973, when, as a hobby, he started collecting photographs and books on the history of Soviet aviation; this has now developed into a major archive. Since the 1980s he has been a professional aviation journalist and writer, with over 50 books published on Soviet/Russian aviation in Russian, English, Polish and Czech, as well as close to 100 magazine features and photo reports. He is also an accomplished photographer, with countless photos published in the Western press; the current edition of Jane's All the World's Aircraft features more than 50 of his photographs
