History
Henry Anson was the first European settler in what is now called Marshalltown.

The determining factor was the location of the east/west railroad across Iowa and the winning company was the Cedar Rapids & Missouri River railroad under lease by the pioneer parent of the Chicago Northwestern Railway. The young town then began growing. By 1900, Marshalltown had 10,000 residents. Many industries began developing in Marshalltown, like Fisher Controls, Lennox International and Marshalltown Company.

Adrian Constantine "Cap" Anson, son of Henry and Jennette Anson, was the first pioneer child born in the new town and is today known as Marshalltown's “first son.” Adrian became a Major League Baseball player and was inducted into the National Baseball Hall of Fame in…
