Brief History of Lodge 47
Rocky Mountain Lodge Local 47, once known as “Pioneer Lodge 47” held its first meeting on October 10th, 1889. At that time it was a mixed lodge with members from local Railroad and Machine Shops. Lodge 47 was officially chartered by the “National Association of Machinist” on October 1st, 1890.
The National Association of Machinist later became the International Association of Machinists and Aerospace Workers (IAMAW).
There have been many changes since then and our local is still a mixed local, but the types of companies our members work at has changed a bit. We are an amalgamated local with workers in many locations throughout Colorado and Cheyenne Wyoming.
The trades and skills our members represents are varied and include: mechanics/diesel mechanics, assemblers, line workers, military/airfield support, medical support and manufacturers just to mention a few.
The historical images below are excerpts taken from a 1990 booklet of the 100th Anniversary celebration for Unions in Colorado.
