John Bailey Peddle (Terre Haute, Indiana, February 27, 1868 – idem, April 6, 1933) was an American mechanical engineer, Professor of Machine Design at the Rose Polytechnic Institute and author,[1] known for his seminal work Construction of Graphical Charts, 1910.

From 1897 until 1933 he was Professor of Machine Design back at the Rose Polytechnic Institute.

[6] The work was written from a mathematical point of view,[7] and required some engineering training.

In 1914 Willard C. Brinton published a similar work for the general audience with no mathematics, called Graphic Methods for Presenting Facts.

[6] Peddle has been member of the American Society of Mechanical Engineers,[8] and the Indiana Academy of Science.
