Aleksis Kivi was born at Nurmijärvi, Finland, in a tailor’s family. In 1846 he left for school in Helsinki, and in 1859 he was accepted to the University of Helsinki, where he studied literature and developed an interest in the theater. His first play was Kullervo, based on a tragic tale from Kalevala. He also met the famous journalist and statesman Johan Vilhelm Snellman. By this time, he had finnicized his Swedish surname Stenvall ('stone bank') to the Finnish Kivi ('stone').
From 1863 onwards, Kivi devoted his time to writing. He wrote 12 plays and a collection of poetry. The novel Seven Brothers took him ten years to write. Literary critics, especially the prominent August Ahlqvist, disapproved of the book, at least nominally because of its realism – romanticism was in its forte at the time – but maybe also because it was written in Finnish, the "peasant’s language", instead of the more "cultural" Swedish. The Fennomans also disapproved of its depiction of not-so-virtuous rural life that was far from their idealized point of view.
In 1865 Kivi won the State Prize for his still often performed comedy Nummisuutarit (The Cobblers on the Heath). However, the less than enthusiastic reception of his books was taking its toll and he was already drinking heavily. His main benefactor Charlotta Lönnqvist could not help him after the 1860s. Physical deterioration and developing schizophrenia set in, and Kivi died in poverty at the age of 37.
