notes: label: Description
content: The citation information for this spiral-bound book is: Maurice Kidjel, <i>The Kidjel Ratio System 5.333/1</i> (Honolulu, 1962). It was received with an example of Kidjel's Cali-Pro proportional dividers (MA.333876), and a warranty card for the Cali-Pro is inside the front cover of the book. After a biographical note, Kidjel provided supposed solutions to the three classic construction problems of Greek antiquity (trisecting the angle, squaring the circle, and doubling the cube).
label: Description
content: Although the Cali-Pro was not needed for these attempted solutions, in part two of the book Kidjel explained how to make these and other, more standard, solutions with the device. Next, he discussed how his ratio applied to the human body. Finally, he explained how to use the Cali-Pro in various fields of industrial design, such as architecture and publishing. A brief biography of Kidjel's business partner, Kenneth W. K. Young, is found inside the back cover. The back cover reproduces a portion of then-U.S. Representative Daniel Inouye's remarks about the Kidjel ratio system, read into the <i>Congressional Record</i> of the 86th Congress.
