Longmont’s reputation as a center for high technology began when the Federal Aviation Administration built an air traffic control center on 17th Avenue in 1962. But that reputation really took off on March 3, 1965, when IBM announced they would open a plant between Boulder and Longmont.
In response, the City of Boulder created a “flagpole annexation.” This legal term describes how cities make “non-contiguous” property part of their city: imagine a narrow strip of land (the pole) connecting to a distant piece of land (the flag). But Longmont was not fazed, and benefited greatly from the arrival of IBM workers, which soon numbered 3,500.
IBM also helped increase diversity in Boulder County, but not without growing pains. After a federal discrimination lawsuit was filed against the company in 1971, they rallied to recruit and promote both women and people of color to high-paying management and programming positions.
Former IBM employees founded Storage Technology (later StorageTek) in 1969, which grew to the largest employer in Boulder County by the 1980s, then hit bankruptcy, rebounded, and finally was sold. Another data storage company, Miniscribe, was founded in 1980 in the basement of a Longmont home. Pressure to achieve profitability eventually led to financial fraud and sale to another tech company, Maxtor. The successor to these and other data storage companies, Seagate, remains a leader in data storage.
Among the many biomedical and other high-tech companies in Longmont today are AMD, Intrado 911, McKesson/CoverMyMeds, Micron Technology and Honeybee Robotics, part of Blue Origin, the aerospace company owned by Jeff Besos.
Join us every Thursday for the rest of the year as we celebrate the triple anniversary of Longmont turning 155, Colorado turning 150, and America turning 250. We will share stories and photos on specific monthly themes tied to the history of the city we call home. This month, we’re shining the spotlight on Longmont’s high-tech legacy.
