In Memory of Michael Tilson Thomas

Michael Tilson Thomas conducts the BSO at the Bernstein Centennial Celebration at Tanglewood

We are saddened to hear the news of the passing of conductor Michael Tilson Thomas. Our thoughts are with his family and friends at this difficult time of loss. 

Thomas had a rich, decades-long association with the Boston Symphony Orchestra. The musicians and administration of the BSO have been privileged to have maintained such a close relationship with Michael as conductor, pianist, composer, and impresario, dating from his debut leading the Tanglewood Music Center Orchestra as a Conducting Fellow in July 1968. In 1969, after winning the Koussevitzky Prize at Tanglewood, Michael was appointed assistant conductor of the Boston Symphony Orchestra. That year he also made his New York debut with the BSO, gaining international recognition when he replaced Music Director William Steinberg mid-concert. The widely acclaimed performance by the then-24-year-old catapulted his career; New York Times classical music critic Harold C. Schonberg noted: “[Thomas] had his golden opportunity and made the most of it. … A tall, thin young man, he came on stage with an air of immense confidence and authority and showed that his confidence was not misplaced.”  

Michael went on to serve as the BSO’s Associate Conductor (1970-73), then, with Colin Davis, as Principal Guest Conductor through the 1975 Tanglewood season. Even after his music director appointments to the Buffalo Philharmonic and San Francisco Symphony, he remained a frequent collaborator with the BSO and Tanglewood Music Center Orchestra dozens of times over four decades both at Symphony Hall and at Tanglewood. In 2009 he presented his musical family memoir, The Tomashefskys: Music and Memories of a Life in the Yiddish Theater at Tanglewood. He also recorded works ranging from Tchaikovsky to Charles Ives with the orchestra. 

Thomas’ most recent performances with the BSO were in the 2018 and 2022 Tanglewood seasons. In August 2018, he led the orchestra in two concerts: his own Agnegram and music by Rachmaninoff and Mahler, followed later that month with works by Bernstein and Copland as part of the special Bernstein Centennial Celebration. He last appeared with the BSO in August 2022, conducting two memorable programs, Beethoven’s Ninth Symphony, as well as Copland’s Third Symphony, Rachmaninoff’s Third Piano Concerto (with pianist Alexander Malofeev), and Rimsky-Korsakov's Dubinushka

We will miss Michael’s extraordinary presence and eloquence, though his memory will live on for generations through his legacy of recordings and music-making at the highest levels.
