Books by Lillian Lieber

Paul Dry Books has republished three of Lillian Lieber's books on mathematics:

  • The Education of T.C. MITS: What Modern Mathematics Means to You
  • Infinity: Beyond the Beyond the Beyond
  • Einstein's Theory of Relativity

Lillian Lieber was the head of the Department of Mathematics at Long Island University. She wrote a series of lighthearted and well-respected math books in the 1940s, including those listed above, and Mits, Wits & Logic. Her husband, Hugh Gray Lieber, was head of the Department of Fine Arts at Long Island University and illustrated many of his wife's books.
