Mark Twain, pseudonym of Samuel Langhorne Clemens, was born in Florida, Missouri on 30 November 1835. He was the sixth child in the family of Jane Lampton and John Marshall Clemens. In 1839 the Twain family moved to the city of Hannibal, Missouri, a port on the Mississippi River. There he received a public school education. When his father died in 1847 the family was left in financial straits. Eleven year old Samuel left school and obtained his first of many jobs working with various newspapers and magazines. Subsequently he worked as a printer in many other cities. Later Clemens was a steamboat pilot on the Mississippi River. In 1861 the writer served briefly as a volunteer soldier in the Confederate cavalry. Later that year he accompanied his brother and tried his hand at silver mining. In 1862 he became a reporter and in 1863 he began signing his articles with the pseudonym Mark Twain. His famous penname Twain adopted from the call ('Mark twain!' – meaning by the mark of two fathoms) used when sounding river shallows. But this isn't the full story: he had also satirized an older writer, Isaiah Sellers, who called himself Mark Twain. In 1870 Twain married Olivia Langdon with whom he had four children.
