Pyotr Ilyich Tchaikovsky was a Russian composer born in 1840 who wrote some of the most popular classical music. He composed many famous works including Swan Lake, The Nutcracker, and 1812 Overture. Tchaikovsky was born into a middle class family and received music lessons from an early age. He had a successful career as a composer and professor of music in Saint Petersburg, but his personal life was complicated by his sexuality in a time when homosexuality was stigmatized. Tchaikovsky died in 1893 at the age of 53 from cholera, though some historians believe his death may have been a suicide.
