It was first climbed on 13 August 1859 by Leslie Stephen, with guides Anton Siegen, Johann Siegen and Joseph Ebener. An account of some of Stephen's first ascents was published by Leslie Stephen in his book The Playground of Europe (1871). The Bietschhorn ascent however is not mentioned in that classic mountaineering book.
