Yakov Hanecki (known in Russia as Yakov Stanislavovich Ganetsky - Яков Станиславович Ганецкий), real name Jakub Fürstenberg (Fuerstenberg) also known as Kuba (15 March 1879 — 26 November 1937) was a prominent Polish communist and close associate of Vladimir Lenin,[1] famous as one of the financial wizards who arranged, through his close working relationship with Alexander Parvus, funding for the Bolsheviks who led the October Revolution of 1917 - after which he served as a middle ranking Soviet official until his arrest and execution in 1937.

Yakov Hanecki was born in Warsaw, Vistula Land, Russian Empire, the son of Stanislav von Fürstenberg, a beer manufacturer of German-Jewish descent, who had adopted Poland as his homeland.

In August 1903, as a member of the Main Administration of the SDKPiL, he was one of two Polish delegates to the Second Congress of the Russian Social Democratic Labour Party (RSDLP) in Brussels.

[2] At the outbreak of the 1905 revolution, Hanecki returned illegally to Warsaw, with Felix Dzerzhinsky to run the SDKPiL's underground organisation, until Jogiches arrived, in October.

[4] Other members included Karl Radek, Josef Unshlicht, Yakov Dolecki - all later high-ranking officials in the Soviet Union - and two future leaders of the Communist Party of Poland, Henryk Domski and Julian Lenski.

He acted as chairman of the three man committee - whose other members were Lenin and Grigori Zinoviev - who looked into whether Roman Malinovsky, the former head of the Bolshevik parliamentary delegation, was a police spy, and wrongly exonerated him.

"[5] In 1915, Hanecki moved via Switzerland to Copenhagen, where he formed a commercial company, Handels-og Eksportkompagniet A/S (Trade and Export Co. Ltd.), with himself as chairman of the board of directors, and his wife as the book keeper.

In January 1917, Hanecki was hauled before a judge for exporting medical goods to Sweden without a licence, fined heavily, expelled from Denmark, and put on a ferry to Stockholm, where he seems to have had no difficulty re-establishing his wholesale business, trading in contraceptives.

[6] After the February revolution, he was active in helping exiled Russian revolutionaries to return to Russia - most notably Lenin, whom he supplied with money for the journey,[7] and greeted when his party arrived in Sweden after crossing Germany in a 'sealed train' in April 1917.

"[8] Hanecki moved to Russia, with Karl Radek, eleven days after the Bolshevik revolution, and was appointed deputy chairman of the state bank, but despite his 21 years in the revolutionary movement and obvious ability as an administrator, he had no significant political influence within the Soviet communist party.

He was accused of having an unauthorized meeting with Polish military intelligence during a September 1933 trip to retrieve a Lenin archive, as well as having been a German spy.
