Communist Party of Brazil
From Moscow Ewert and Szabo were first sent to the United States, with Ewert using the pseudonym "Harry Berger" during his brief stay. From there the pair proceeded to Brazil as Comintern Representative to the Communist Party of Brazil. Following an abortive insurrection against the regime of Getúlio Vargas in November 1935, Ewert was arrested in Rio de Janeiro and was subjected to severe torture by authorities seeking the whereabouts of opposition leader Prestes.
