Historical Note

The International Association of Machinists (IAM) was founded by a group of 19 railroad machinists in Atlanta, Georgia in 1888. Primarily orientated to the railroad aspects of the machinists’ trade, the new union spread rapidly following the path of the "boomers" along southern, mid-western and western railroad lines.

Gradually, the IAM began to broaden the base of its membership in response to the rapidly developing machine age of the late 19th century, and, in 1895, sought and gained affiliation with the American Federation of Labor.

Today, the trade union that started as an association of railroad mechanics operates in a wide variety of industries and has one of the most diversified memberships in organized labor. It is the largest union in the aircraft and aerospace industries, one of the largest on the railroads, the largest union of auto mechanics, the largest dealing with the airlines and the largest in the business machine industry.

Local Lodge 225 was chartered in Dayton in 1892 and has since dealt with a number of important industries in the Miami Valley including aircraft manufacturers’ tools and die makers, machine toolers, foundries, printers, auto dealers and bicycle manufacturers. Currently, Lodge 225 has a membership of approximately 900 and agreements with 23 local businesses.
