Solomon Grigorevich Mogilevsky (Russian: Соломо́н Григо́рьевич Могиле́вский; 1885 – March 22, 1925) headed the Soviet foreign intelligence service, the INO of the GPU, from 1921 until May 1922.
He was then sent to head the GPU in the South Caucasus region,[1] where he was involved in the suppression of the 1924 August Uprising in the Georgian SSR.
In 1906 he left Russia for Switzerland where he met Vladimir Lenin, who recommended him to be admitted into Bolshevik section of the party.
The plane, which also carried two other high-ranking Soviet security officials (Georgi Atarbekov and Aleksandr Myasnikyan), blew up in mid-air not far from Tiflis.
There has always been a strong suspicion that the young Georgian airman Ambako Sagaradze, who was piloting the plane, crashed deliberately, killing himself and his passengers.
