Herman Melville was an American novelist, poet, and sailor who wrote the classic novel, Moby Dick. Herman Melville was born in New York on August 1, 1819. His father’s name was Allan Melville and his mother’s name was Maria. Herman was the third of eight children. His brothers and sisters played an important role in his career as well as in his emotional life.

Herman's education began in 1824 when he was five years old. Around the time, the Melvilles moved into a newly built house at 33 Bleecker Street in Manhattan. Herman attended Albany Academy from October 1830 to October 1831, where he took a standard preparatory course. In 1831, he had to leave school, as his parents couldn’t pay for it.

From the age of 18, Herman sailed as a cabin boy on a packet boat, then worked for a while as a teacher; in 1841, he went on the whaling ship "Acushnet" to the South Seas and was captured by the aborigines. Three years later, he got home and started a writing career.

Melville wrote his main masterpiece “Moby Dick or the White Whale.” "Moby Dick" became one of the most well-known novels of the XIX century. This novel is about a sailor Ishamael who wanted to catch a whale called Moby Dick. He was sure that this whale killed many sailors.

1. Where was Herman born?

2. What was Herman’s mum name?

3. When did his travelling to the South Seas start?
