Quartet, later called the Czech Quartet, was founded, with Karel Hoffmann, first violin, Josef Suk, second violin, Oskar Nedbal, viola, and Otakar Berger, cello. It is said that Nedbal and Suk had been two of Dvořák's "most promising" students at the Conservatory and took the initiative in founding the Quartet. As of 1891 Dvořák had written 11 string quartets, six of which had been premiered, and these were available as part of the repertory of the Quartet on tour, as were the two quartets of Smetana. United States From 1892 to 1895, Dvořák was the director of the National Conservatory of Music in New York City. He began at a then-staggering $15,000 annual salary. Emanuel Rubin describes the Conservatory and Dvořák's time there. The Conservatory had been founded by Jeannette Thurber, a wealthy and philanthropic woman, who made it open to women and black students as well as white men, which was unusual for the times. Dvořák's original contract provided for three hours a day of work, including teaching and conducting, six days a week, with four months' vacation each summer. The Panic of 1893, a severe economic depression, depleted the assets of the Thurber family and other patrons of the Conservatory. In 1894, Dvořák's salary was cut to $8,000 per year and moreover was paid only irregularly. The Conservatory was located at 126–128 East 17th Street, but was demolished in 1911 and replaced by what is today a high school. Dvořák's main goal in America was to discover "American Music" and engage in it, much as he had used Czech folk idioms within his music. Shortly after his arrival in America in 1892, Dvořák wrote a series of newspaper articles reflecting on the state of American music. He supported the concept that African-American and Native American music should be used as a foundation for the growth of American music. He felt that through the music of Native Americans and African-Americans, Americans would find their own national style of music. Here Dvořák met Harry Burleigh, who later became one of the earliest African-American composers. Burleigh introduced Dvořák to traditional African-American spirituals. In the winter and spring of 1893, Dvořák was commissioned by the New York Philharmonic to write Symphony No. 9, From the New World, which was premiered under the baton of Anton Seidl, to tumultuous applause. Clapham writes that "without question this was one of the greatest triumphs, and
