Contralto Marian Anderson becomes the first person of color to perform at the Metropolitan Opera in Giuseppe Verdi's Un ballo in maschera.

The Metropolitan Opera (commonly known as the Met) is an American opera company based in New York City, resident at the Metropolitan Opera House at Lincoln Center, currently situated on the Upper West Side of Manhattan. The company is operated by the non-profit Metropolitan Opera Association, with Peter Gelb as general manager. As of 2018, the company's current music director is Yannick Nzet-Sguin.

The Met was founded in 1883 as an alternative to the previously established Academy of Music opera house, and debuted the same year in a new building on 39th and Broadway (now known as the "Old Met"). It moved to the new Lincoln Center location in 1966.

The Metropolitan Opera is the largest classical music organization in North America. Until 2019, it presented about 27 different operas each year from late September through May. The operas are presented in a rotating repertory schedule, with up to seven performances of four different works staged each week. Performances are given in the evening Monday through Saturday with a matine on Saturday. Several operas are presented in new productions each season. Sometimes these are borrowed from or shared with other opera companies. The rest of the year's operas are given in revivals of productions from previous seasons. The 201516 season comprised 227 performances of 25 operas.The operas in the Met's repertoire consist of a wide range of works, from 18th-century Baroque and 19th-century Bel canto to the Minimalism of the late 20th and 21st century. These operas are presented in staged productions that range in style from those with elaborate traditional decors to others that feature modern conceptual designs.

The Met's performing company consists of a large symphony orchestra, a chorus, children's choir, and many supporting and leading solo singers. The company also employs numerous free-lance dancers, actors, musicians and other performers throughout the season. The Met's roster of singers includes both international and American artists, some of whose careers have been developed through the Met's young artists programs. While many singers appear periodically as guests with the company, others maintain a close long-standing association with the Met, appearing many times each season until they retire.

Marian Anderson (February 27, 1897 – April 8, 1993, aged 96) was an American contralto. She performed a wide range of music, from opera to spirituals. Anderson performed with renowned orchestras in major concert and recital venues throughout the United States and Europe between 1925 and 1965.

Anderson was an important figure in the struggle for African-American artists to overcome racial prejudice in the United States during the mid-twentieth century. In 1939 during the era of racial segregation, the Daughters of the American Revolution (DAR) refused to allow Anderson to sing to an integrated audience in Constitution Hall in Washington, D.C. The incident placed Anderson in the spotlight of the international community on a level unusual for a classical musician. With the aid of First Lady Eleanor Roosevelt and her husband President Franklin D. Roosevelt, Anderson performed a critically acclaimed open-air concert on Easter Sunday, April 9, 1939, on the Lincoln Memorial steps in the capital. She sang before an integrated crowd of more than 75,000 people and a radio audience in the millions.

On January 7, 1955, Anderson became the first African-American singer to perform at the Metropolitan Opera. In addition, she worked as a delegate to the United Nations Human Rights Committee and as a Goodwill Ambassador for the United States Department of State, giving concerts all over the world. She participated in the civil rights movement in the 1960s, singing at the March on Washington for Jobs and Freedom in 1963. The recipient of numerous awards and honors, Anderson was awarded the first Presidential Medal of Freedom in 1963, the Congressional Gold Medal in 1977, the Kennedy Center Honors in 1978, the National Medal of Arts in 1986, and a Grammy Lifetime Achievement Award in 1991.
