What U.S. first lady was nicknamed "The Steel Magnolia"?

Eleanor Rosalynn Carter (née Smith; born August 18, 1927) is the wife of the 39th President of the United States, Jimmy Carter, and served as the First Lady of the United States from 1977 to 1981. She has for decades been a leading advocate for numerous causes, perhaps most prominently for mental health research. She was politically active during her White House years, sitting in on Cabinet and policy meetings as well as serving as her husband's closest adviser. She also served as an envoy abroad, to Latin America in particular.

She was the first First Lady to keep her own office in the East Wing. She also oversaw her family at the White House. Her daughter, Amy, attracted much public attention. The two youngest sons, Chip and Jeff, and their families also lived in the White House. Other members of the family, including son Jack and his wife and children, were frequent visitors. Rosalynn Carter's Secret Service code name was "Dancer".

Rosalynn Carter created and serves as the chair of The Carter Center Mental Health Task Force, an advisory board of experts, consumers, and advocates promoting positive change in the mental health field. She hosts the annual Rosalynn Carter Symposium on Mental Health Policy, bringing together nationwide leaders in the mental health field.

When Jimmy ran for President in 1976, Rosalynn was very active in the campaign. The press nicknamed her the "steel magnolia" for her sweetness and drive.
