Basil Kahan. Ottmar Mergenthaler : The Man and His Machine: A Biographical Appreciation of the inventor on his centennial. Oak Knoll Press 2000 Hardcover in DJ Very Good/Very Good Octavo 244 pp
"After a wide ranging career, Kahan took early retirement to pursue his lifelong interest in the printing trade. He found many conflicting reports about the German immigrant to the US Mergenthaler (1845-99) and his invention of an automatic typesetting machine that later became the Linotype, and decided to set the record straight with a biographical appreciation. He particularly narrates the conflicts with the typographers' unions and with his financial backers." Annotation c. Book News, Inc., Portland, OR (booknews.com)
