Michael Tilson Thomas, New World Symphony founder and conductor, dies at 81

Michael Tilson Thomas lived a “beautiful dream” promoting the arts and classical music in Miami. Now, he rests.

The renowned American conductor, composer, visionary and co-founder of Miami Beach’s prestigious New World Symphony, died Wednesday. He was 81.

Surrounded by friends and family, Tilson Thomas died at his home in San Francisco from glioblastoma multiforme, an aggressive form of brain cancer, the New World Symphony confirmed. His husband Joshua Robison died Feb. 22. The couple is survived by their nieces and nephews.

Tilson Thomas’ illustrious musical career spanned decades. Even after his cancer diagnosis in 2021, he continued to make music and perform live until April 2025, the New York Times reported. His many accolades include curating and conducting at Carnegie Hall, winning 12 Grammy Awards, receiving the National Medal of Arts, being inducted into the California Hall of Fame and receiving Kennedy Center Honors in 2019. He was the music director of the San Francisco Symphony for 25 years and founding artistic director of the New World Symphony for 34 years.

“Michael Tilson Thomas was one of the pioneers of creating the new Miami of the late 20th, early 21st centuries,” said Michael Spring, the former longtime director of the Miami-Dade County Department of Cultural Affairs. “The Miami that’s now known as being a place where new work and new voices in the arts come from. Michael Tilson Thomas was absolutely instrumental in helping to create and sustain that reputation.”

Tilson Thomas’ New World Symphony, an ensemble and intensive three-year fellowship program for music school graduates to hone their craft, and its home at the New World Center in Miami Beach, are considered to be crown jewels in the Miami area’s art scene. Tilson Thomas co-founded the New World Symphony along with philanthropists Ted and Lin Arison in 1987.

“The New World Symphony has been such a beautiful dream and I am looking forward, right here in Miami Beach, to continue that dream into the future,” Tilson Thomas told the Miami Herald in 2019.

In March 2022, Tilson Thomas — known as MTT — announced he was stepping down from his role as New World Symphony’s artistic director due to his health. He assumed the less strenuous role of artistic director laureate and famed French conductor Stéphane Denève was hired as artistic director.

“MTT was a master of wrestling a dream into reality. He coached us all in the process. First the dream, then the hard work—of mastering a piece of music, of building a career, of establishing an institution,” said New World Symphony President and CEO Howard Herring in a statement. “One of MTT’s most profound ideas was the New World Symphony, where the imagined future meets the hard work, every day. After 38 years, it is clear that MTT’s concept of an orchestral academy is here to stay. We celebrate his artistry and his persistence, personal qualities that have guided us to this moment and will fuel us going forward.”

Early life and career

As a child, Michael Tilson Thomas couldn’t walk past a piano without reaching for its keys. It’s no wonder he grew up to be one of the country’s most revered pianists and composers.

The performing arts ran in the family. Tilson Thomas was born in Los Angeles Dec. 21, 1944, the only child of Ted and Roberta Thomas. His father was a stage manager and producer for New York theaters and later worked on film and television in Hollywood. His mother established the research department of Columbia Pictures and taught English and social studies in Los Angeles, the New York Times reported. Tilson Thomas’ grandparents were New York Yiddish theater superstars Boris and Bessi Thomashefsky.

At age 12, he met his future husband, Robison, as part of North Hollywood’s Walter Reed Junior High School orchestra, according to SF Gate magazine. Thomas played oboe and piano, and Robison played cello. They weren’t really friends at the time, Tilson Thomas recalled in an interview, but the two reconnected year later. They became a couple in 1976 and married in 2014.

Thomas enrolled in the University of Southern California in 1962 and was mentored by German American composer Ingolf Dahl. By the late ‘60s, the music world was buzzing about Tilson Thomas, often comparing him to his mentor Leonard Bernstein.

In 1969, he was appointed assistant conductor of the Boston Symphony Orchestra. At just 24, Tilson Thomas raised eyebrows and wooed critics when he substituted for an ailing Boston Symphony conductor William Steinberg mid-concert at Carnegie Hall. A New York Times review at the time wrote, “A tall, thin young man, he came onstage with an air of immense confidence and authority and showed that his confidence was not misplaced.”

Tilson Thomas later moved on to other music ensembles and institutions, including the Buffalo Philharmonic, Berlin Radio Symphony Orchestra, Cleveland Orchestra, Israeli Philharmonic and New York Philharmonic. But some colleagues and players criticized him as “brash” and “arrogant.” In 1978, he was arrested at Kennedy International Airport and charged with carrying drugs, an incident he later said tarnished his reputation but served as a learning moment.

“People found out I was not the model of a nice Jewish boy,” he told New York Times Magazine in 1995. “The event pushed me from wunderkind to desperado. It hurt, and I probably did not get some jobs I might have gotten, but hurt is important and instructive for a musician.”

Just a few years later, he embarked on a journey that would transform both his own legacy and Miami’s budding arts and culture landscape.

A New World in Miami Beach

Tilson Thomas’ idea of a “real institutional home” for young musicians caught the attention of Ted Arison, the founder of Carnival cruise lines. In 1981, Arison and his wife Lin founded nonprofit YoungArts, a program that supports young artists across disciplines. They found a kindred spirit in Tilson Thomas, who wanted to create an environment for early-career classical musicians to get their feet wet.

The New World Symphony started out at the Lincoln Theatre, where it helped boost the revival of Lincoln Road in the late ‘80s and early ‘90s. Sarah Arison, the granddaughter of Ted and Lin Arison, said her earliest memory is holding her late grandparents’ hands at just 3 years old to walk into the Lincoln Theatre to watch the symphony.

The last year has been difficult emotionally due to the deaths of her grandmother last October and Robison in February, Sarah Arison said. Despite his aggressive cancer diagnosis, Tilson Thomas was thankfully able to spend invaluable time with Denève and the New World fellows.

“Even if it wasn’t a shock to everybody, it’s still devastating,” she said.

A major part of Tilson Thomas’ legacy is his passion for sharing music with as many people as possible, especially those who don’t buy theater tickets, she said. Sarah Arison recalled her grandfather’s excitement to install old-school televisions on the outside of the Lincoln Theatre to broadcast live classical music to the sidewalk. “I want everybody to be able to see what New World is doing,” her grandfather told her.

That concept grew into the now iconic WallCasts, a high-quality livestream of concerts happening inside the New World Center that is projected onto the outside of the building for the public to enjoy for free. The idea has been replicated by music institutions across the country and around the world.

The construction of the New World Center, designed by famed architect (and Tilson Thomas’ former baby sitter) Frank Gehry, further cemented Miami’s reputation as an arts hub worth paying attention to, Spring said. The high-tech $160 million building was completed in 2011.

Herring, who announced his retirement from the symphony last month, recalled how Tilson Thomas’ values impacted the design of the building. In an early meeting, Tilson Thomas told Gehry to focus on the doors: “Don’t make this a formal front door, a suit-and-tie kind of front door. Make it an invitation.” Gehry came back with the design for the facade 18 months later.

“If you prop the doors of the atrium open, people who are walking the sidewalk in front of the building do not see a barrier. They see invitation, and they quite naturally walk through those doors,” Herring told the Herald. “We are in the city together. Who we are inside the door and who we are outside the door is all one piece.”

Denève, the symphony’s current artistic director, leading the symphony is just as much as a dream for him as it was for Tilson Thomas. In several interviews, Herring noted that Denève is the perfect fit to continue Tilson Thomas’ vision.

“ I will forever treasure the cathartic effect his music-making had on me,” Denève said in a statement. “For MTT, the most profound question was what happens after the performance—what people take away with them and what we, as artists, do to enrich the lives and souls of our audience. Michael’s ultimate gift is his inspiration of the generations to come”

Music — making it, sharing it, teaching it, performing it — was Tilson Thomas’ “greatest joy,” Sarah Arison said.

“I will remember him on stage with the fellows, always,” she said. “That is where he had the most energy, the most joy. I think this is how he would like to be remembered as well.”
