About the article "Henri Matisse", section "The war years".

Candidate passages:
He and his wife of 41 years separated in 1939.
In 1941, he underwent surgery in which a colostomy was performed.
Afterwards he started using a wheelchair, and until his death he was cared for by a Russian woman, Lydia Delektorskaya, formerly one of his models.
With the aid of assistants he set about creating cut paper collages, often on a large scale, called "gouaches découpés".
His Blue Nudes series feature prime examples of this technique he called "painting with scissors"; they demonstrate the ability to bring his eye for colour and geometry to a new medium of utter simplicity, but with playful and delightful power.
In the 1940s he also worked as a graphic artist and produced black-and-white illustrations for several books and over one hundred original lithographs at the Mourlot Studios in Paris.
In 1941, a nursing student named Monique Bourgeois responded to an ad placed by Matisse for a nurse.
A platonic friendship developed between Matisse and Bourgeois.
He discovered that she was an amateur artist, and taught her about perspective.
After Bourgeois left the position, Matisse sometimes contacted her to request that she model for him.
Bourgeois became a Dominican nun in 1946.
Matisse was much admired and repeatedly referred to by the Greek Nobelist poet Odysseas Elytis.
Elytis was introduced to Matisse through their common friend Tériade, during the work on the "Cutouts".
Matisse had painted the wall of the dining room of Tériade's residence, the "Villa Natacha" in Saint-Jean-Cap-Ferrat, which Elytis also mentioned in his poems.
Matisse, thoroughly unpolitical, was shocked when he heard that his daughter Marguerite, who had been active in the Résistance during the war, was tortured (almost to death) in a Rennes prison and sentenced to the Ravensbrück concentration camp.
(Marguerite avoided further imprisonment by escaping from the Ravensbrück-bound train, which was halted during an Allied air strike; she survived in the woods until rescued by fellow resisters.
)Matisse's student Rudolf Levy was killed in the Auschwitz concentration camp in 1944.
In 1947 he published "Jazz", a limited-edition artist's book of about one hundred prints of colourful paper cut collages, accompanied by his written thoughts.
Tériade, a noted twentieth-century art publisher, arranged to have Matisse's cutouts rendered as pochoir (stencil) prints.
Rudolf Levy (1875—1944) was a renowned painter who worked with and was a student of Henri Matisse.
According to historian Cecil Roth, Levy was one of the "pioneers of the modern art movement in Germany.
"Rudolf Levy was born in Stettin, Germany (now Szczecin, Poland) in 1875.
He fought for the German Army in World War I and was awarded the Iron Cross.
In 1933, Levy fled from Berlin to Paris and in 1940 escaped to Florence, Italy.
In 1943 he was deported to Auschwitz concentration camp, where he died in 1944. 
Four people were killed in the assault: 20-year-old UCSB students Nicholas Bourdakis and Christoper Divis, 27-year-old San Francisco resident Elie Israel, and 20-year-old Santa Barbara City College student Ruth Levy.
Albert Levy, 27, brother to Ruth, was critically injured but survived.
His injuries consisted of crushed legs and a severely battered head. 
By the mid-1980s, Levy had left the Jewish Defense League to form the Jewish Defense Organization.
After a bomb at the California offices American Arab Anti-Discrimination Committee killed its West Coast director, Alex Odeh, both the Jewish Defense League and the Jewish Defense Organization came under investigation by the Federal Bureau of Investigation Two weeks earlier, according to the "New York Times", The American-Arab Anti-Discrimination Committee's New York office appeared on a list entitled "Enemies of the Jewish People" handed out in Washington, DC by Levy.
Levy was quoted in a UPI report denying responsibility for the murder: "We had no hand in this, but this man deserved what he got."
Asked about the attacks by the New York Times, Levy said "We aren't claiming credit, but it couldn't happen to better people, more deserving people.
They're getting a taste of their own medicine.
"Levy was charged with four counts of attempted murder and other charges after he opened fire on late JDL leader Irv Rubin in 1989, hitting an innocent bystander.
Rubin was attempting to serve a subpoena on Levy.
Levy was acquitted of all charges except one count of felony assault with a deadly weapon, for which he served 18 months of a 4½ year sentence.
Levy pleaded guilty in 2000 to unrelated charges that he assaulted a 12 year-old boy in New York State.
Levy collects information on neo-Nazis, the KKK and Arab organizations.
A 1989 "Village Voice" article on Jewish militants reported: "His uncanny ability to track down KKK members and neo-Nazis astounded federal officials.
"Levy does appear to possess membership lists of neo-Nazi groups and KKK members across the U.S.," a confidential FBI memorandum reported."
