National Conservatory of Music of America in New York City. The President of the National Conservatory of Music in America, Jeannette Thurber, offered Dvořák an annual salary of $15,000 – an incredibly lavish sum for the era (), twenty-five times what he was paid at the Prague Conservatory. While in the United States, Dvořák wrote his two most successful orchestral works: the Symphony From the New World, which spread his reputation worldwide, and his Cello Concerto, one of the most highly regarded of all cello concerti. In the summer of 1893, Dvořák moved from New York City to Spillville, Iowa, following the advice of his secretary, J.J. Kovarík. Dvořák had originally planned to come back to Bohemia, but Spillville was made up of mostly Czech immigrants, and thus he felt less homesick; Dvořák referred to it as his "summer Vysoka." This is where he wrote his most famous piece of chamber music, his String Quartet in F major, Op. 96, which was later nicknamed the American Quartet. Shortly after his time in Iowa, Dvořák extended his contract at the National Conservatory for another two years. However, the economic crisis of April 1893 resulted in Thurber's husband's loss of income, and directly influenced the National Conservatory's funding. Shortfalls in payment of his salary, along with increasing recognition in Europe and an onset of homesickness, led him to leave the United States and return to Bohemia in 1895. All of Dvořák's nine operas, except his first, have librettos in Czech and were intended to convey the Czech national spirit, as were some of his choral works. By far the most successful of the operas is Rusalka. Among his smaller works, the seventh Humoresque and the song "Songs My Mother Taught Me" are also widely performed and recorded. He has been described as "arguably the most versatile... composer of his time". The Dvořák Prague International Music Festival is a major series of concerts held annually to celebrate Dvořák's life and works. Biography Early years Dvořák was born in Nelahozeves, near Prague, in the Austrian Empire, and was the eldest son of František Dvořák (1814–94) and his wife, Anna, née Zdeňková (1820–82).
