Maxim Gorky
Alexei Maximovich Peshkov ( or  – 18 June 1936), primarily known as Maxim Gorky (), was a Russian and Soviet writer, a founder of the socialist realism literary method and a political activist. He was also a five-time nominee for the Nobel Prize in Literature. Around fifteen years before success as a writer, he frequently changed jobs and roamed across the Russian Empire; these experiences would later influence his writing. Gorky's most famous works were "The Lower Depths" (1902), "Twenty-six Men and a Girl" (1899), "The Song of the Stormy Petrel" (1901), "My Childhood" (1913-1914)," Mother" (1906), "Summerfolk" (1904) and "Children of the Sun" (1905). He had an association with fellow Russian writers Leo Tolstoy and Anton Chekhov; Gorky would later mention them in his memoirs.
