Brown received her B.A. from
Swarthmore College and A.M. and PhD. from
Radcliffe College and
Harvard University. In 2009 Elizabeth A. R. Brown was elected the Second Vice-President of the
Medieval Academy of America and in 2010–2011 served as its president. She taught at
Brooklyn College in New York for decades and taught at
Yale and
Berkeley after retiring. In her critique, Brown highlights the potential for constructs to influence research agendas and warns constructs that we use to analyze the past can be exclusive. In 1987, Brown was elected a Fellow of the
Medieval Academy of America (MAA). She later served as the president of the MAA in 2010–2011. In 2024, she gave a bequest to the University of Pennsylvania Libraries (the Penn Libraries) to establish an archive to hold the papers of medieval historians – including her own collection – and to endow a curator to manage it. ==Works==
