A mining town on the Mesabi Range, Chisholm was founded by Archibald Mark Chisholm.
Chisholm is in the center of the Mesabi Iron Range, one of the four iron ranges in the Arrowhead Region of Minnesota.
Chisholm is also the birthplace of Orvin David Thompson.
With a railroad line to Duluth and plenty of mining work available in and near town, the population of Chisholm grew rapidly, and by 1908, the town had more than 6,000 people and 500 buildings. On September 5, 1908, a fast-moving forest fire obliterated the town due to the dry conditions during the late summer and wood construction of nearly all the buildings in town. Many people sought escape by going into the lake. No one died in the fire. Afterwards, building codes were enhanced, and by the next summer, more than 70 fireproof buildings had been erected. Chisholm became a city in 1934.
