George Gershwin (; born Jacob Gershwine; September 26, 1898 – July 11, 1937) was an American composer and pianist whose compositions spanned popular, jazz and classical genres. Among his best-known works are the orchestral compositions Rhapsody in Blue (1924) and An American in Paris (1928), the songs "Swanee" (1919) and "Fascinating Rhythm" (1924), the jazz standards "Embraceable You" (1928) and "I Got Rhythm" (1930), and the opera Porgy and Bess (1935), which included the hit "Summertime".

Gershwin studied piano under Charles Hambitzer and composition with Rubin Goldmark, Henry Cowell, and Joseph Brody. He began his career as a song plugger but soon started composing Broadway theater works with his brother Ira Gershwin and with Buddy DeSylva. He moved to Paris, intending to study with Nadia Boulanger, but she refused him, afraid that rigorous classical study would ruin his jazz-influenced style; Maurice Ravel voiced similar objections when Gershwin inquired about studying with him. He subsequently composed An American in Paris, returned to New York City and wrote Porgy and Bess with Ira and DuBose Heyward. Initially a commercial failure, it came to be considered one of the most important American operas of the twentieth century and an American cultural classic.

Gershwin moved to Hollywood and composed numerous film scores. He died in 1937, only 38 years old, of a brain tumor.

His compositions have been adapted for use in film and television, with many becoming jazz standards.
