The American Machinist is a popular American trade magazine of the international machinery industries and most especially their machining aspects. Published since 1877, it was a McGraw-Hill title for over a century before becoming a Penton title in 1988.[2] In 2013 it transitioned from combined print/online publication to online-only.


The journal was founded in 1877 by Horace B. Miller and Jackson Bailey at 96 Fulton Street in New York City. Fred H. Colvin explained:

In 1888, the editors decided to launch another title, specific to the railroading industry, called Locomotive Engineer. They asked Colvin's father, Henry F. Colvin, to recommend someone to become the new title's editor. He recommended an American Machinist correspondent from Pueblo, Colorado, whose writing he considered to be of good quality. The man was hired, and this introduction to technical publishing was auspicious, because John A. Hill went on to be a cofounder of McGraw-Hill.

American Machinist was published weekly from 1877 to 1960[3] by various New York City companies, from the original American Machinist Publishing Company, through John A. Hill's Hill Publishing Company, to McGraw-Hill from 1909 onward. From 1968 to 1988, McGraw-Hill issued it biweekly and later monthly,[4] briefly titling it American Machinist & Automated Manufacturing during 1986–88.[5] Since 1988 it has been published by Penton;[2] in 2013 it transitioned from combined print/online publication to online-only.

William Harris, a professor emeritus of Middlebury College, summarized that the American Machinist appeared weekly since "after the American Civil War, and was published continuously through the 19th and into the 20th century. This time period spans a very important interval, at the beginning of which new machinery began to appear in response to arms needs arising from the war, and the concept of mass production was invented. Interchangeable parts for military equipment followed immediately, and gave a new sense of what machines could do, in fact what they were going to have to do, as a matter of course in the future."[6]

Long-time editors or coeditors included Frederick A. Halsey and Fred H. Colvin. Other editor-in-chiefs were Leon P. Alford from 1911 to 1917, and John H. Van Deventer from 1917 to 1919.

For decades, American Machinist and several other key trade journals, including the Industrial Press's Machinery (of which Colvin was the founding editor), helped machinists, from machine tool builders and job shop operators to factory hands, to keep abreast of current practice and new developments in a way that they formerly had not. Both editorial offices also issued handbooks for machinists (American Machinists' Handbook and Machinery's Handbook).

In 1969 the American Machinist magazine was awarded the National Magazine Award, for its special issue, “Will John Garth Make It?” The study of U.S. industry's role in combating unemployment, especially among those that companies might consider unemployable, included Mr. Garth, a 26-year-old high school dropout and parolee.
