Bertha von Suttner was of "gentle birth" as it was phrased in her era, but her father was impoverished. In 1873 she took a position as governess for the wealthy von Suttners. When the son fell in love with her, the von Suttners refused permission for the marriage. Bertha then went to Paris (from Prague) having answered an ad Alfred Nobel posted for a housekeeper/secretary. She was with Nobel only briefly, but the books say she influenced his ideas, and they corresponded the rest of his life. After a few weeks in Paris Bertha returned to Austria (Prague was part of the Austrian empire) and secretly married Arthur Gundaccar Freiherr von Suttner. She in time was officially, then, a baroness and a countess.
Bertha was interesting; her whole family was interesting. She has this to say about her brother, Arthur Franz Graf Kinsky von Wchinitz und Tettau, whom she never saw after 1872:
My brother was still alive, to be sure, but, except for an exchange of letters once in a great while, we were quite out of touch with each other. So in these recollections I have had nothing to say of him. He was an odd fish, living perfectly aloof from mankind and isolated in a small Dalmatian city, occupying himself with floriculture and chess. His company consisted of a number of cats. Solitary walks along the seashore, the reading of botanical and mineralogical works, were his only passions. ....[H]is death....occurred a few years ago...
Bertha herself, Nobel laureate of peace, died two months before the outbreak of World War I.
