Glenn Herbert Gould was born at home in Toronto on September 25, 1932, to Russell Herbert ("Bert") Gold and Florence ("Flora") Emma Gold (née Greig), Presbyterians of Scottish and English ancestry. His maternal grandfather was a cousin of Norwegian composer Edvard Grieg. The family's surname was changed to Gould informally around 1939 in order to avoid being mistaken as Jewish, because of a series of reasons centering on the prevailing anti-Semitism of prewar Toronto and the Gold surname's Jewish association. Gould had no Jewish ancestry, though he sometimes made jokes on the subject, like "When people ask me if I'm Jewish, I always tell them that I was Jewish during the war."
Gould's interest in music and his talent as a pianist became evident very early on. Both his parents were musical, and his mother, especially, encouraged the infant Gould's early musical development. Prior to his birth, his mother planned for Glenn to become a successful musician, especially a pianist, and thus exposed him to music during her pregnancy. As a baby, he reportedly hummed instead of crying and wiggled his fingers as if playing chords, leading his doctor to predict that Glenn would "be either a physician or a pianist". By the age of three, Glenn's perfect pitch was noticed and Glenn learned to read music before he could read words. When presented with a piano, young Glenn was reported to strike single notes and listen to their long decay, a practice his father Bert noted was different from typical children. Glenn's interest in the piano proceeded side by side with an interest in composition; he would play his own little pieces for family, friends, and sometimes large gatherings, including, in 1938, a performance at the Emmanuel Presbyterian Church (a few blocks from the Gould house) of one of own compositions. When he was six, Glenn was taken for the first time to hear a live musical performance by a celebrated soloist; this had a tremendous effect on him. He later described the experience:
It was Hofmann. It was, I think, his last performance in Toronto, and it was a staggering impression. The only thing I can really remember is that, when I was being brought home in a car, I was in that wonderful state of half-awakeness in which you hear all sorts of incredible sounds going through your mind. They were all orchestral sounds, but I was playing them all, and suddenly I was Hofmann. I was enchanted.
As a young child, Glenn was taught by his mother. He began attending The Royal Conservatory of Music in Toronto, where he studied piano with Alberto Guerrero, organ with Frederick C. Silvester, and music theory with Leo Smith, at the age of ten. Gould passed his final Conservatory examination in piano at the age of twelve (achieving the 'highest marks of any candidate'), thus attaining 'professional standing as a pianist' at that age. One year later he passed the written theory exams, qualifying for the ATCM diploma (Associate, Toronto Conservatory of Music).
In 1945, he gave his first public performance, playing the organ, and the following year, he made his first appearance with an orchestra, the Toronto Symphony Orchestra, in a performance of the first movement of Beethoven's 4th piano concerto. His first solo recital followed in 1947, and his first recital on radio was with the CBC in 1950. This was the beginning of his long association with radio and recording. He founded the Festival Trio chamber group in 1953 with the cellist Isaac Mamott and the violinist Albert Pratz.
In 1957 Gould embarked on a tour of the Soviet Union, becoming the first North American to play there since World War II. His concerts featured Bach, Beethoven, and the serial music of Schoenberg and Berg, which had been suppressed in the Soviet Union during the era of Socialist Realism. Gould made his Boston debut in 1958, playing for the Peabody Mason Concert Series. One audience member was so moved that she wrote a letter to the Editor of the Boston Herald commenting, "If I never hear Bach's Goldberg Variations again, I feel with all my heart that I have heard the ultimate, and am grateful".
On April 10, 1964, Gould gave his last public performance, playing in Los Angeles, at the Wilshire Ebell Theater. Among the pieces he performed that night were Beethoven's Piano Sonata No. 30, selections from Bach's
The Art of Fugue, and Paul Hindemith's Piano Sonata No. 3. Gould performed fewer than two hundred concerts over the course of his career, of which fewer than forty were overseas. For pianists such as Van Cliburn, two hundred concerts would have amounted to about two year's touring. For the rest of his life, Gould eschewed live performance, focusing instead on recording, writing, and broadcasting. Towards the end of his life, he began conducting; he had earlier directed Bach's
Brandenburg Concerto No. 5 and the cantata
Widerstehe doch der Sünde from the harpsipiano (a piano with metal hammers to simulate a harpsichord's sound), and Gustav Mahler's Symphony No. 2 (
Urlicht part) in the 1960s. His last recording was as a conductor, conducting Wagner's
Siegfried Idyll in its original chamber music scoring. He had intended to give up the piano at the age of 50, spending later years conducting, writing about music, and composing.
On September 27, 1982, after experiencing a severe headache, he suffered a stroke, which paralyzed the left side of his body. He was admitted to the Toronto General Hospital, and his condition rapidly deteriorated. By October 4, there was evidence of brain damage, and Gould's father decided that his son should be taken off life support. He is buried in Toronto's Mount Pleasant Cemetery, next to his parents. The first few measures of the
Goldberg Variations are carved on his marker.
