2-time Pulitzer Prize winner Elliott Carter died at age 103 on Monday.
The classical composer died in New York City, according to the music publishing company Boosey and Hawkes. No cause of death was indicated.
After experimenting with neoclassical music, Carter went on to write atonal rhythmically complex music, ranging from ballets to vocal, instrumental, chamber and orchestral pieces. His compositions have been performed across the world.
With a career that spanned over nine decades, Carter was extremely productive later in life, publishing over 40 works from the ages of 90 and 100.
The New York City native's last work was published in Aug. 2010, entitled "12 Short Epigrams" for piano.
In addition to his career as a composer, Carter held teaching posts at prestigious schools including Columbia University, the Peabody Conservatory, Yale University, and the Juilliard School, among others.
Along with two Pulitzer Prize Awards, Carter earned the Trustees Award distributed by the Grammy Awards to non-performing artists in 2009, and earned widespread recognition for his work.
Many social media outlets have been flooded with those mourning the composer on Tuesday.
Twitter user Geeta posted, "RIP Elliott Carter, gone at age 103. A true legend of music, whose life traced a history of the 20th century and beyond."
"Doubts assuaged, sadly," wrote Steve. "Goodbye, Elliott Carter. Watching the world catch up to you during your final decade was a thrill and an honor."
"Sad to hear of Elliott Carter's death," wrote Niall O'Rourke.
Team Classical honored Carter by posting a quote, writing: "Elliott Carter: 'I didn't care whether my music was original or not original, I just wanted to make it a loving kind of thing.'"
Carter leaves behind his son and his grandson. The composer would have celebrated his 104th birthday next month.
