Grigoryevitsj Emil Gilels, sometimes represented as Hilels (Григо́рович Гі́лельс,Ukrainian: Емі́ль Эми́ль Григо́рьевич Ги́лельс Russian:; Gi'lelis Emi'li Grego'rievitsj) (Odessa, 19 October 1916 – Moscow, October 14, 1985) was a Ukrainian pianist and is widely regarded as one of the greatest pianists of the 20th century.
Both parents were musicians of Gilels. He got his first piano lessons when he was six years old, by Yakov Tkach, a rigidly disciplined man who focused on scales and study. Gilels later said that this strict training formed the basis of his technique.  Gilels made his public debut when he was twelve years was in June of the year 1929 with a well-received program of Beethoven, Scarlatti, Chopin and Schumann.  In 1930, he went to the Conservatory of Odessa where he was tutored by Berta Reingbald, whom Gilels credited as a formative influence for him was.
In 1933 the newly established Gilels won at the age of 16, All Soviet Union Piano Competition. After graduating in 1935 he moved to Moscow where he studied under Heinrich Neuhaus until 1937 at the Moscow Conservatory. A year later, he won the Ysaÿe International Festival in Brussels (now the Queen Elisabeth Competition), where he and Arturo Benedetti Michelangeli participants as Mary Johnstone left behind. 
Gilels was the first artist from the Soviet Union permitted to frequently travel to make it to the West. After the Second World War he began in 1947 with various tours throughout Europe, and in 1955 he made his debut in the United States; He then played Tchaikovsky's first piano concerto in Philadelphia. In 1952 he went to teach at the Moscow Conservatory. In his last years he remained in the Soviet Union and came rarely more abroad.
He was working on a project on Beethoven's piano sonatas for Deutsche Grammophon finalize when he died in 1985 in Moscow after a medical examination (for his recording of the "hammerklavier" Sonata-he received a Gramophone Awardin 1984). Sviatoslav Richter, who knew Gilels well and likewise at Neuhaus at the Moscow Conservatory had studied, said that Gilels was accidentally killed when an incompetent doctor from the Kremlin hospital gave him the wrong injection during a normal checkup. 
Gilels is universally admired for his superb technical control and flaming show.  his interpretations of the Central German-Austrian classics formed the heart of his repertoire, especially Beethoven, Brahms, andSchumann; He was equally illuminative with Scarlatti, Bach, as in his game of the 20th century for example, Debussy's music, Bartók, and Prokofiev. His Liszt was first class and his recordings of the Hungarian Rhapsody nº 6 and the Sonata in b minor have acquired classic status in some circles.
