George Jacob Gershwin ( ; September 26, 1898 July 11, 1937) was an American composer and pianist. Gershwin's compositions spanned both popular and classical genres, and his most popular melodies are widely known. Among his best-known works are the orchestral compositions "Rhapsody in Blue" (1924) and "An American in Paris" (1928) as well as the opera "Porgy and Bess" (1935).
George Jacob Gershwin's opera "Porgy and Bess" was released after his death in 1935
The context shows George Jacob Gershwin's death date to be 1937, so it "Porgy and Bess" was in fact released two years prior to his death. The system was likely fooled because it cannot understand the meaning of the dates in parentheses.
