Alexander Sergeyevich Pushkin was a Russian poet, playwright, and novelist of the Romantic era who is considered by many to be the greatest Russian poet and the founder of modern Russian literature.Pushkin was born into Russian nobility in Moscow. His matrilineal great-grandfather was Abram Petrovich Gannibal, who was kidnapped from what is now Cameroon (there are various scholarly views on this) and raised in the household of Peter the Great. He published his first poem at the age of fifteen, and was widely recognized by the literary establishment by the time of his graduation from the Tsarskoye Selo Lyceum. While under the strict surveillance of the Tsar's political police and unable to publish, Pushkin wrote his most famous play, the drama Boris Godunov. His novel in verse, Eugene Onegin, was serialized between 1825 and 1832.
Pushkin was fatally wounded in a duel with his brother-in-law, Georges-Charles de Heeckeren d'Anthès, also known as Dantes-Gekkern, a French officer serving with the Chevalier Guard Regiment who attempted to seduce the poet's wife, Natalia Pushkina.
Yesterday morning I ate a breakfast. And after that I decided to go to the cinema to see a premier of the famous film and offered my friend to join me. But he suggested to go to the swimming pool instead, because we swam in the pool only last month. I packed my clothes and the clean towel and my backback became heavy. We met at the bus station. He was riding a motorbike. He told me the lattest news and mentioned one scientist. That scientist was very intelligent and really amazing. He finished a huge project. He invented some high-technological device. My friend found that information in the internet.
