query: When did Victor Lvovich Kibalchich take the name Victor Serge?
passage: Victor Serge
Serge's first published article was written in September 1908. Under the pen name "Le Rétif" ("The Maverick" or "The Stubborn One"), Serge wrote many articles for Le Révolté and, starting in 1909, L'Anarchie, a journal founded by Albert Libertad, whom Serge and his friends considered to be a hero. Serge at this stage was an outspoken supporter of individualist anarchism and illegalism, often clashing with the editor of L'Anarchie, André Roulot (aka "Lorulot"), who favoured less inflammatory rhetoric. In 1910, after a schism in L'Anarchie, Lorulot departed and Serge was named as the new editor of the paper. During this time, Serge was in a relationship with Rirette Maitrejean, another anarchist activist.
passage: William Jacques
He began stealing books from the Lindley Library of the Royal Horticultural Society in Pimlico under the name Victor Santoro some time after June 2004, when an inventory was last taken. He also used the pseudonym "David Fletcher". He moved books around to hide the gaps he left when removing books, which he concealed under his tweed jacket. Staff later realised that he signed in when he had both arms free, but never signed out.
