The late twentieth century saw literary theory expand into an unusually wide set of disciplines, drawing scholars whose training in literature pulled them toward philosophy, law, linguistics, and beyond. Barbara Johnson, born in Boston on October 4, 1947, worked across several of those fields simultaneously, holding roles as a literary critic, literary scholar, philosopher, linguist, translator, journalist, and university teacher throughout her career.

Educated at Oberlin College and subsequently at Yale University, Johnson went on to hold two distinct positions at Harvard University. She served as professor of English and Comparative Literature and also held the Fredric Wertham Professor of Law and Psychiatry in Society chair — two appointments whose titles, taken together, mark the breadth of disciplinary territory her professional life covered. That she occupied both a humanities professorship and a chair explicitly linking law and psychiatry at the same institution speaks to the range her work encompassed.

Her practice extended into translation as well as into journalism, alongside the more formal registers of literary criticism and philosophical inquiry. Working in the English language, she brought to her various vocations the kind of sustained attention that each of those fields demands in its own way. As a university teacher at Harvard, she held a position that placed her in contact with students and colleagues across the fields her dual appointments represented.

Johnson received a Guggenheim Fellowship, a recognition awarded to scholars and artists of demonstrated achievement. She died on August 27, 2009, in Cambridge — the city that had also housed the Harvard institution with which she remained associated across the later decades of her career. The Library of Congress Name Authority File records her under the label Johnson, Barbara, 1947–2009, a designation that traces the full arc of her life from its beginning in Boston to its end sixty-one years later.
