Lattice Theory by Garrett Birkhoff. Although Lieber retired from Long Island University in 1954, she continued to write and publish into the 1960s. Personal obscurity Few details of Lillian Lieber's life and career have survived, even at Long Island University. She died in Queens, New York just weeks shy of her 100th birthday. She came from a well-educated Jewish family. Details can be found in the out of print book, Yesterday, that was written by her cousin Miriam Shomer Zunser in the 1930s. Unusual typography In addition to enlivening her books with illustrations (or "psyquaports" ) by her husband, Hugh Gray Lieber (who was head of the Department of Fine Arts at Long Island University), Lillian often chose an unusual scheme of typography which is self-explained in this example from her Preface to The Education of T. C. MITS: This is not intended to befree verse.Writing each phrase on a separate linefacilitates rapid reading,and everyoneis in a hurrynowadays. T.C. MITS was an acronym for "The Celebrated Man In The Street," a character who, like George Gamow's Mr Tompkins, served as a device for bringing concepts in higher mathematics and physics to the general public. The MITS character was central to Lieber's populist approach to education, and she often laced her expositions with passages extolling the virtues of the democratic system. "The Lillian Lieber Standard" In her book, The Einstein Theory of Relativity, Lillian Lieber stated her views on the inclusion of mathematics in books intended for "the celebrated man [or woman] in the streets:" ...just enough mathematics to HELP and NOT to HINDER the lay reader... Many 'popular' discussions of Relativity without any math at all have been written, but we doubt whether even the best of these can possibly give to a novice an adequate idea of what it is all about.... On the other hand, there are many [books on relativity] that are accessible to experts only." The Cavendish Press in Ann Arbor, Michigan, has adopted Lillian's rule of thumb with some elaboration. Works Although her works were broadly influential (including a special paperback edition of The Education of T. C. MITS that was circulated to American servicemen during World War II), they remained out of print for decades. Starting in 2007, publisher Paul Dry Books has reissued The Education of T.C. MITS, Infinity, and The Einstein Theory of Relativity. 1931 Non-Euclidean Geometry, Academy Press. 1932 Galois and
