Ruth Mitchell was born 30 April 1889 in
Milwaukee, Wisconsin, the daughter of Harriet Danforth (Becker) Mitchell and
John Lendrum Mitchell, who a few years later would become a U.S. congressman and senator. Her grandfather was the wealthy banker and railroad tycoon
Alexander Mitchell; her grandmother,
Martha Reed Mitchell, was well known in charity, art and society circles. She had two sisters and two brothers: William (known as Billy), who became a general, and John, a
World War I aviator who died flying over France in 1917. She was educated at
Milwaukee-Downer College and then at
Vassar College. Mitchell was married three times but always preferred to use her birth name. Her first husband was William Van Ryneveld Van Breda, and with him she had two children: John Lendrum Van Breda (b. 1914) and Ruth Van Breda. John joined the
Royal Air Force during World War II and was killed in action in Egypt in May 1941. This marriage was ended by William Van Breda's death. Mitchell's second husband was
Stanley Knowles, a British public school teacher who was stationed in Albania as a diplomat during World War II. They separated in the early 1930s, and in 1943 Mitchell went to Reno, Nevada, to get a divorce. In May 1944, Mitchell married Benjamin H. Jackson of Idaho, who worked in the mining industry. Although Mitchell inherited enough money not to have to work, she had an adventurous temperament. An article about her in 1955 described her as one of the "pioneer women airplane pilots," though it is uncertain when or where she learned this skill. ==World War II==
