Michael Tilson Thomas, the conductor who led the San Francisco Symphony for twenty-five years and founded the New World Symphony, has died at the age of 81.
He passed away on Wednesday, April 22, 2026, at his home in San Francisco. His death follows a battle with glioblastoma, a form of brain cancer he was diagnosed with in 2021. His passing comes two months after the death of his husband and professional partner, Joshua Robison, on February 24, 2026.
A Career of Longevity and Leadership
Tilson Thomas held a central place in musical life for over half a century. His career gained international attention in 1969 with the Boston Symphony Orchestra, but he is most closely associated with the institutions he helped build and sustain:
- San Francisco Symphony: As Music Director from 1995 to 2020, he expanded the orchestra’s repertoire and international profile, later serving as Music Director Laureate.
- New World Symphony: He co-founded this orchestral academy in 1987, creating a training ground for young professionals that has influenced ensembles across the globe.
- London Symphony Orchestra: He served as Principal Conductor from 1988 to 1995, and held the title of Conductor Laureate until his death.
Focus on Education and Media
Beyond his work on the podium, Tilson Thomas utilized media and technology to broaden the reach of classical music. His Keeping Score project provided historical and analytical context for major symphonic works, emphasizing musical literacy for a digital audience. His recordings, particularly of the works of Gustav Mahler and various American composers, earned him twelve Grammy Awards.
Final Appearances
Despite the progression of his illness, Tilson Thomas continued to conduct during the 2024–2025 season. He led performances earlier in April 2026 to mark his 80th birthday year, maintaining his long-standing connection with the San Francisco Symphony and its audience.
He is survived by a global community of musicians, students, and colleagues.
