Emerson String Quartet

The Emerson String Quartet, also known as the Emerson Quartet, was an American string quartet initially formed as a student group at the Juilliard School in 1976. It was named for American poet and philosopher Ralph Waldo Emerson and began touring professionally in 1976. The ensemble taught in residence at The Hartt School in the 1980s and is currently the quartet in residence at Stony Brook University. Both of the founding violinists studied with Oscar Shumsky at Juilliard, and the two alternated as first and second violinists for the group. The Emerson Quartet was one of the first such ensembles with the two violinists alternating chairs.

The Emerson Quartet was inducted into the Classical Music Hall of Fame in 2010. As of May 2014, they had released more than thirty albums and won nine Grammy Awards, as well as the prestigious Avery Fisher Prize in 2004. In 2017, the Emerson String Quartet Institute became part of the College of Arts and Sciences at Stony Brook University. The institute enables members of the current quartet and the quartet's former cellist David Finckel to mentor and coach student string quartets.

In August 2021, the quartet announced its plan to disband at the end of the 2022–2023 season in order to focus on teaching and solo work. In the final season of concerts in 2022-23, the quartet gave farewell performances throughout North America and Europe. The final performance of the quartet took place on Sunday, October 22, 2023, in New York City, featuring a program of Beethoven's Op. 130 string quartet (with its original ending, the Grosse Fuge, Op. 133) and Schubert's String Quintet D. 956. The performance was filmed by Tristan Cook for a documentary, Four Rational People, released in 2026.
