Baroness Bertha von Suttner (9 June 1843 – 21 June 1914) was a novelist, radical (organizational) pacifist, and the first woman to be a Nobel Peace Prize laureate.
Suttner became a leading figure in the peace movement with the publication of her novel, Die Waffen nieder! ("Lay Down Your Arms!") in 1889 and founded an Austrian pacifist organization in 1891. She gained international repute as editor of the international pacifist journal Die Waffen nieder!, named after her book, from 1892 to 1899. Her pacifism was influenced by the writings of Henry Thomas Buckle, Herbert Spencer, and Charles Darwin. Though her personal contact with Alfred Nobel had been brief, she corresponded with him until his death in 1896, and it is believed that she was a major influence in his decision to include a peace prize among those prizes provided in his will, which she won in 1905.
