Edith Tudor-Hart (née Edith Suschitzky; 1908–1973) was an Austrian-British photographer, communist-sympathiser and spy for the Soviet Union.
 Some of her work is in the National Gallery in London.
 Brought up in a family of socialists, she trained in photography at Walter Gropius's Bauhaus in Dessau, and carried her political ideals through her art.
 Through her connections with Arnold Deutsch, Tudor-Hart was instrumental in the recruiting of the Cambridge Spy ring which damaged British intelligence from World War II until their discovery in the late 1960s.
 She recommended Litzi Friedmann and Kim Philby for recruitment by the KGB and acted as an intermediary for Anthony Blunt and Bob Stewart when the "rezidentura" at the Soviet Embassy in London suspended its operations in February 1940.

Gottfried Ochshorn (April 6, 1915 – October 23 (or 20), 1943) was a Jewish Austrian communist student activist and fighter during the Spanish Civil War.
 At the end of the Spanish Republic he went to France where he worked as a translator for German troops while also active in forging papers to aid the French Resistance.

Nikola Hristov Geshev (Bulgarian: Никола Христов Гешев ) (13 April 1896 – 1984 probably) was a famous Bulgarian policeman between the two World Wars.
 A native of Sofia, Geshev had fought in the First World War.
 As a youngster he became interested in Marxism for a short time.
 After the end of the war he traveled to Fascist Italy where he was impressed by Benito Mussolini and the fascist state.
 When he returned to Bulgaria he started to work in the Police.
 He reached his peak in the end of the 1930s, when he became commander of second department of the Bulgarian Secret Police.
 He was known as a "super policeman" and was a strong enemy of the Bulgarian Communist Party.
 In 1942 Geshev succeed to break the Central committee of the Communist Party.
 Furthermore, he introduced his own agents inside the Bulgarian Communist Party.
 Some sources prove that even the communist leader of Bulgaria Todor Zhivkov was an agent of Geshev.
 The same goes for many other communist politicians.
 After the Soviets took over Bulgaria, Geshev's destiny is unknown.
 There are many theories, but the most common of them say that either he was killed near Plovdiv by partisans or he fled to Turkey and then to West Germany.
 Less common versions of his destiny made him working for the CIA or for the KGB.
 During the Cold War some of the communist leaders of Bulgaria were afraid that if Geshev become an agent of the KGB he could show his records.

Adin is an uncommon family name found today in England, the United States (particularly New York City), New Zealand, Sweden, the Basque country, Turkey and Israel.
 Since the name occurs in the Old Testament, it has been suggested that the name has Jewish origins since it is mentioned in the Bible four times.
 However, the Jewish Genealogical Society of Great Britain have no records of this as a Jewish family name.
 The Consolidated Jewish Family Name Index of U.S.-based Avotaynu indicates Adin is a Jewish family name that existed in Poland and Belarus.
 However this may be a phonetic coincidence since a name with so few letters might exist in every culture.
