Aldo Parisot, a renowned cellist who toured the world as a soloist and settled into a career as an eminent teacher that included a 60-year tenure at the Yale School of Music, died on Saturday at his home in Guilford, Conn. He was 100.

His death was announced by his son, Dean Parisot, a film director and producer in Los Angeles. The cellist had retired from Yale only last June.

During the busiest stage of his solo career Mr. Parisot performed with the major orchestras of Berlin, London, Paris and Munich, and with conductors including Leopold Stokowski, Pierre Monteux and Leonard Bernstein, winning plaudits for his warm, focused sound; prodigious technique; and a temperament that balanced passion and elegance.

For a 1955 New York Philharmonic appearance under the conductor Walter Hendl, he gave the premiere of Heitor Villa-Lobos’s Cello Concerto No. 2, one of many works Mr. Parisot would commission during his career to expand the cello repertory.
