Grete Keilson

The following year she became assistant to Georgi Dimitrov, the manager of Western European offices of Comintern, who was living in Berlin under the pseudonym of Rudolf Hediger, having fled his native Bulgaria and been sentenced to death in 1924.

Working under the codename of Marianne, she helped prepare and assemble forged visas and travel documents that were produced by a counterfeiting group in the Berlin suburb of Wilmersdorf.

[2] After Dimitrov was arrested on 9 March 1933 for alleged complicity in starting the Reichstag fire, for which he was later acquitted, Keilson used forged documents herself to flee to Copenhagen.

In 1943 she became involved with the National Committee for a Free Germany (NKFD) and the League of German Officers (BDO), and visited prisoner of war camps to find recruits.

After Klaus Fuchs was released from prison in Britain where he had been convicted on espionage charges and deported to East Germany in 1959, Keilson greeted him on arrival at Berlin Schönefeld Airport and they married later that year.
