Ira Gershwin (born Israel Gershovitz; December 6, 1896 – August 17, 1983) was an American lyricist who collaborated with his younger brother, composer George Gershwin, to create some of the most memorable songs in the English language of the 20th century. With George, he wrote more than a dozen Broadway shows, featuring songs such as "I Got Rhythm", "Embraceable You", "The Man I Love" and "Someone to Watch Over Me". He was also responsible, along with DuBose Heyward, for the libretto to George's opera Porgy and Bess.
