many outspoken artists of his era, Szyk was suspected by the House Un-American Activities Committee, which accused him of being a member of the Joint Anti-Fascist Refugee Committee and six other suspicious organizations. Szyk himself, however, repudiated these accusations of alleged sympathy for communism; his son George sent Judge Simon Rifkind a memorandum outlining his father's innocence. Arthur Szyk died of a heart attack in New Canaan on September 13, 1951. He was eulogized by Rabbi Ben Zion Bokser, who said: Legacy The immense popularity Szyk enjoyed in the United States and Europe in his lifetime gradually flagged after his death. From the 1960s to the end of the 1980s, the artist's works were seldom exhibited in American museums. This changed in 1991 when the non-profit organization The Arthur Szyk Society was established in Orange County, California. The founder of the Society, George Gooche, rediscovered Szyk's works and staged the exhibition "Arthur Szyk – Illuminator" in Los Angeles. In 1997, the seat of the Society was transferred to Burlingame, California, and a new Board of Trustees was elected, headed by rabbi, curator and antiquarian Irvin Ungar. The Society's work resulted in staging many exhibitions of Szyk's works in American cities in the 1990s and 2000s. The Society also maintains a large educational website, holds lectures, and produces publications on the artist. In April 2017, the Ungar collection of his work, consisting of 450 paintings, drawings and sketches, was purchased for $10.1 million by the University of California, Berkeley's Magnes Collection of Jewish Art and Life, through a donation by Taube Philanthropies, the largest single monetary gift to acquire art in UC Berkeley history.
