Sir Edward Thomas ("Ted") Downes, CBE (17 June 1924 – 10 July 2009) was an English conductor, specialising in opera.
He was associated with the Royal Opera House from 1952, and with Opera Australia from 1970. He was also well known for his long working relationship with the BBC Philharmonic and for working with the Netherlands Radio Orchestra. Within the field of opera, he was particularly known as a conductor of Verdi.
He and his wife, Lady (Joan) Downes, committed assisted suicide at the Dignitas clinic in Switzerland on 10 July 2009, an event that received significant media coverage.
Downes was born in Birmingham, England in 1924, the son of a bank teller. He began to learn the piano and violin at age five and was also a choirboy at King Edward's School, learning the organ and becoming choir master when his voice broke at 13. He left school at the age of 14 to earn his living in a low-paid position at the City of Birmingham Gas Department.
Having spent his lunch hours studying by himself in Birmingham Central Library, he won a scholarship at the age of 16 to the University of Birmingham. Because his parents believed that a musical career was immoral, they made him leave home and he spent his university time as a fire watcher, living in the fire station, while he studied English literature and music. He began playing the horn. A scholarship to the Royal College of Music to study composition (with Ralph Vaughan Williams and R. O. Morris) and horn (with Frank Probin) followed. Only weeks after starting the course, Probin sent Downes as his deputy on a tour with the London Symphony Orchestra, which continued over the years Downes spent at the College, but on leaving the Royal College he decided that orchestral playing would not be his career. He played in the orchestra at Sadler's Wells in the opening performances of Benjamin Britten's Peter Grimes in 1945, and at Covent Garden in ballet performances (The Sleeping Beauty) in 1946, while still at the Royal College of Music. He also played for the orchestra of the San Carlo Opera Company.
