While teaching at Barnard in 1939, she was among the founders of American studies as an academic discipline and later authored the book, "European Economic Reconstruction". During World War II, she worked for the Office of Strategic Services in Washington, analyzing dispatches from the French Resistance. She had met Walt Rostow at a Paris seminar in 1937. After their marriage a decade later, the couple lived in Geneva for three years.
MIT
When she was being considered as MIT's first female tenured professor in the early 1950s, the MIT Faculty Club remained an all-male enclave. When she went to the Provost and asked to be admitted, he denied her request. At which point she retorted,"well then you can just build me my own Faculty Club." The policy was changed that same day.
She brought to the University of Texas impressive academic credentials and internationally recognized expertise in the area of public policy. Among her other presidential appointments, President Ronald Reagan appointed her to the board of the U.S. Institute of Peace, which she later chaired. Elspeth Rostow was a force at U.T. from 1969 until her death. She was initially drawn to Austin with her husband, Walt Whitman Rostow by the research value of Lyndon B. Johnson’s presidential papers. She served as dean of both the LBJ School of Public Affairs and UT’s Division of General and Comparative Studies. As dean, she recruited professors such as Barbara Jordan. Despite her administrative ability, she considered herself first to be a teacher, eventually working as a professor for over half a century. She had remarked, "I enjoy the simple act of teaching. It's not transmitting information, it's enticing people into the world of ideas."
1990s
In 1991, she co-founded The Austin Project, a comprehensive community investment program in children and young people. Her husband once said, "She's extraordinarily concerned with other people. She is an administrator with a green thumb. When she runs something, it flourishes." In 1996, The Alcalde described Rostow as having "never a hair nor a thread nor a word out of place. She is quietly intense, notoriously elegant, eloquent, proper, and continually self-deprecating."
Death
She died, aged 90, following a heart attack, in 2007, survived by her two children, Ann and Peter, and a granddaughter, Diana Rostow.
