From the Los Angeles Times in the USA:
Provocative figurative painter
October 24, 2007
John Russell credited him with bringing “the subject back into painting” and “history-painting back to life.” Two works in the exhibition, “The Murder of Rosa Luxembourg [sic; Luxemburg. See also here.]” and “Isaac Babel Riding With Budenny,” offer what Russell called “an element of straightforward left-wing pamphleteering.” That tendency would surface time and again in Mr. Kitaj’s work.
His first museum exhibition came in 1965 at the Los Angeles County Museum of Art. Critic William Wilson noted that much of the work appeared “autobiographical” and that the reigning pop art style “was visible in the poster-like punch of Kitaj‘s compositions.”
