Elgin, Illinois

The Indian Removal Act of 1830 and the Black Hawk Indian War of 1832 led to the expulsion of the Native Americans who had settlements and burial mounds in the area, and set the stage for the founding of Elgin. Thousands of militiamen and soldiers of Gen. Winfield Scott’s army marched through the Fox River valley during the war, and accounts of the area’s fertile soils and flowing springs soon filtered east.

In New York, James T. Gifford and his brother Hezekiah Gifford heard tales of this area ripe for settlement, and travelled west. Looking for a site on the stagecoach route from Chicago to Galena, Illinois, they eventually settled on a spot where the Fox River could be bridged. In April 1835, they established the city, naming it after the Scottish tune “Elgin”.

Early Elgin achieved fame for the butter and dairy goods it sold to the city of Chicago. Gail Borden established a condensed milk factory here in 1866, and the local library was named in his honor. The dairy industry became less important with the arrival of the Elgin Watch Company. The watch factory employed three generations of Elginites from the late 19th to the mid 20th century, when it was the largest producer of fine watches in the United States (the factory ceased production in 1965 and was torn down in the summer of 1966) and the operator of the largest watchmaking complex in the world. Today, the clocks at Chicago’s Union Station still bear the Elgin name.

Elgin has a long tradition of education and invention. Elgin is home to the Elgin Academy, the oldest coeducational, non-sectarian college preparatory school west of the Allegheny Mountains. Elgin High School boasts five Navy admirals, a Nobel Prize winner, a Pulitzer Prize winner, a Tony Award winner, two Academy Award–winning producers, Olympic athletes and a General Motors CEO among its alumni. Elgin resident John Murphy invented the motorized streetsweeper in 1914 and later formed the Elgin Sweeper Corporation. Pioneering African-American chemist Lloyd Hall was an Elgin native, as was the legendary marketer and car stereo pioneer Earl “Madman” Muntz and Max Adler, founder of the Adler Planetarium in Chicago, America’s first planetarium.

Local historian E. C. Alft has written several books and an ongoing newspaper column about Elgin’s history.
