Mieczysław Broński (also known as Warszawski-Broński or Broński-Warszawski, and M. J. Braun;[1] Russian: Мечислав Генрихович Бронский (Варшавский); Mechislav Genrikhovich Bronsky; 1882 – 1 September 1938) was a Russian-Polish communist, Soviet diplomat, economist and academic, and a victim of the Great Purge.
In 1902, he joined the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL), led by Rosa Luxemburg and Leo Jogiches.
[5] In June 1917, he reached Petrograd, where he joined the Bolsheviks, worked in the party's Agitprop department, and edited the Polish-language newspaper Trybuna.
[2] After the Bolshevik Revolution, in November 1917, he worked for the state bank, and April supervised the first conference for prisoners of war (such as Bela Kun and Josip Broz Tito) who had converted to Bolshevism.
[1] However he was very critical of Paul Levi's leadership of the Communist Party of Germany during the Kapp Putsch and was then recalled to Moscow.
Bronski was arrested on September 9, 1937, and accused of being part of a terrorist plot, during a mass round-up of Polish nationals living in the Soviet Union.
The former French communist, Boris Souvarine, thought it inevitable that he would be a victim of the purges because "a man like Bronski – cultured, polite, irreproachable – could not help but attract the murderous animadversion of the Despot.
