Samuel Osmond Barber II (March 9, 1910 – January 23, 1981) was an American composer of orchestral, opera, choral, and piano music. He is one of the most celebrated composers of the 20th century: music critic Donal Henahan stated that "Probably no other American composer has ever enjoyed such early, such persistent and such long-lasting acclaim." His Adagio for Strings (1936) has earned a permanent place in the concert repertory of orchestras. He was awarded the Pulitzer Prize for Music twice: for his opera Vanessa (1956–57) and for the Concerto for Piano and Orchestra (1962). Also widely performed is his Knoxville: Summer of 1915 (1947), a setting for soprano and orchestra of a prose text by James Agee. At the time of his death, nearly all of his compositions had been recorded.
William Grant Still (May 11, 1895 – December 3, 1978) was an African-American classical composer who wrote more than 150 compositions. He was the first African-American to conduct a major American symphony orchestra, the first to have a symphony (his first symphony) performed by a leading orchestra, the first to have an opera performed by a major opera company, and the first to have an opera performed on national television. He is often referred to as "the Dean" of African-American composers.
Howard Harold Hanson (October 28, 1896 – February 26, 1981) was an American composer, conductor, educator, music theorist, and champion of American classical music. As director for 40 years of the Eastman School of Music, he built a high-quality school and provided opportunities for commissioning and performing American music. He won a Pulitzer Prize (in 1944 for his Symphony no. 4) and received numerous other awards.
