John Coolidge Adams is an American composer and conductor, born in 1947, associated with the minimalist and post-minimalist movements and based for much of his career in the San Francisco Bay Area; he has also served as Creative Chair of the Los Angeles Philharmonic. His output spans orchestral, operatic, choral, chamber, and electroacoustic music, and is particularly noted for operas built around historical events, including Nixon in China, Doctor Atomic, and Antony and Cleopatra, alongside orchestral works such as Harmonielehre and Short Ride in a Fast Machine.

Adams is regarded as one of the most performed and influential American composers of his generation, having synthesized minimalist techniques with late-Romantic orchestral color as a reaction against strict modernism and serialism. He won the Pulitzer Prize for Music in 2003 for On the Transmigration of Souls and has received the Grawemeyer Award and the Erasmus Prize, with the Library of Congress acquiring his manuscripts in 2023 in recognition of his standing in American music.
