Elizabeth Lewisohn Eisenstein (October 11, 1923 – January 31, 2016) was an American historian of the French Revolution and early 19th-century France.

[3] Eisenstein was visiting professor at Wolfson College, Oxford, and published her lectures from that period as Grub Street Abroad.

[8] From the age of 50, Eisenstein began competing in senior tennis tournaments, becoming well-known and winning three national grand slams between 2003-2005.

Eisenstein's work brought historical method, rigor, and clarity to earlier ideas of Marshall McLuhan and others, about the general social effects of such media transitions.

Paul Needham, now Librarian at Princeton University’s Scheide Library, described it as "almost impossible to comprehend" and suffering "from more general flaws of historical method: an unconcern for exact chronology; a lack of historical context; an exclusive reliance of [sic] secondary writings, not always accurately absorbed, not always particularly relevant …" [13] The Printing Press as an Agent of Change lays out Eisenstein's thoughts on the "Unacknowledged Revolution," her name for the revolution that occurred after the invention of print.

Print also "standardized and preserved knowledge which had been much more fluid in the age of oral manuscript circulation"[14] Eisenstein recognizes this period of time to be very important in the development of human culture; however, she feels that it is often overlooked, thus, the 'unacknowledged revolution'.
