"Alexander Pushkin was born may 26 in Moscow.Most of his life was spent in St. Petersburg
In my childhood the summer months, he usually spent with his grandmother in Moscow in Selo Zakharov around Moscow.Early childhood experiences are reflected in Pushkin's sing, written somewhat later.
He wrote many books, here are some of them:
Eugene Onegin
The bronze horseman
Dubrovsky
Blizzard
The tale of Tsar Saltan 
"Ruslan and Lyudmila"- the most famous Pushkin's book.This is the first finished poem, which he began writing while still in high school."
