Pyotr Ilyich Tchaikovsky (7 May 1840 – 6 November 1893) was a Russian composer of the Romantic period. He was the first Russian composer whose music made a lasting impression internationally. Tchaikovsky wrote some of the most popular concert and theatrical music in the classical repertoire, including the 1812 Overture, his First Piano Concerto, the Violin Concerto, the Romeo and Juliet Overture-Fantasy, several symphonies, the opera Eugene Onegin, and the ballets Swan Lake, The Sleeping Beauty and The Nutcracker.
Although musically precocious, Tchaikovsky was educated for a career as a civil servant as there was little opportunity for a musical career in Russia at the time and no public music education system. When an opportunity for such an education arose, he entered the nascent Saint Petersburg Conservatory, from which he graduated in 1865.
