Else Kleen (1882-1968), also known under her news paper pseudonym Gwen, was a Swedish journalist and author. She was a well known participator in public debate in the Swedish press for sixty years. She was a reporter at Dagens Nyheter in 1906-1910, Stockholms Dagblad 1910 and Stockholms-Tidningen 1911-1961. She was co-founder of the Hjälpföreningen för psykisk hälsovård (Association for Mental Health Care) and a member of its board in 1917-68, and a board member of Långholmen prison on 1946-68. As an author, she is perhaps most known as a fashion journalist, advising women on how to dress elegant and at the same time practical for a small cost. As a social reformer, she is known for her struggle for a humane treatment of the insane and prison inmates.
