Writers whose work Otava has published over the years include Frans Emil Sillanpää, Eino Leino, Paavo Haavikko, Pentti Saarikoski and Laila Hirvisaari. The parent company Otava Group also owns Suomalainen Kirjakauppa.
Otava was founded in 1890 by Hannes Gebhard and Eliel Aspelin-Haapkylä to publish Finnish national literature.Alvar Renqvist (fi) became managing director in 1893 and was the main figure during the company's early years. His descendants (surname fennicized to Reenpää) have continued his work so that Otava remains, in spite of its size, to a large extent a family company. 1906 saw the completion of the new headquarters right in the centre of Helsinki. In 1908 printing press operations began and in 1916 the printing of magazines got under way. The first magazine to be launched was Suomen Kuvalehti, which still comes out weekly. From 1945 to 1991 the company was listed in the Helsinki Stock Exchange. In 1955 a new printing house was put up in Keuruu, near Jyväskylä. During the 1960s Otava faced grave financial difficulties but was able to pull through by rationalizing operations. In 1998 it bought out its rival company WSOY from the jointly owned Yhtyneet Kuvalehdet, a large publisher of magazines.
