During the mid and late 1800s Springfield was dominated by industrialists including O. S. Kelly, Asa S. Bushnell, James Leffel, P. P. Mast and Benjamin Warder. Asa S. Bushnell built the Springfield, Ohio Bushnell Building where the patent attorney to the Wright Brothers, Harry Aubrey Toulmin, Sr., wrote the 1904 patent to cover the invention of the airplane. To promote the products of his agricultural equipment company, P. P. Mast started the Farm and Fireside magazine.

In 1902 A.B. Graham, then the superintendent of schools for Springfield Township in Clark County, established a "Boys' and Girls' Agricultural Club." Approximately 85 children from 10 to 15 years of age attended the first meeting on January 15, 1902 in Springfield, Ohio, in the basement of the Clark County Courthouse. This was the start of what would be called the "4-H Club" within a few years, quickly growing to a nationwide organization. (4-H stands for "Head, Heart, Hands, and Health".) The first "projects" included food preservation, gardening and elementary agriculture. Today, the Courthouse still bears a large 4H symbol under the flag pole at the front of the building to commemorate its part in founding the organization. The Clark County Fair is the second largest fair in the state (only the Ohio State Fair is larger) in large part to 4H still remaining very popular in the area.
From 1916 to 1926, 10 automobile companies operated in Springfield. Amongst them: The Bramwell, Brenning, Foos, Frayer-Miller, Kelly Steam, Russell-Springfield and Westcott. The Westcott, know as the car built to last, was a six-cylinder four door sedan manufactured by Burton J. Westcott of the Westcott Motor Car Company. Burton and Orpha Westcott however, are better known for having contracted the world renowned architect Frank Lloyd Wright to design their home in 1908 at 1340 East High Street. The Westcott House, a sprawling two story stucco and concrete house has all the features of Wright's prairie style including horizontal lines, low-pitched roof, and broad eaves. It is the only Frank Lloyd Wright prairie style house in the state of Ohio. The property was purchased in 2000 by the Frank Lloyd Wright Building Conservancy (Chicago, IL), and as part of a prearranged plan, the house was then sold to a newly formed local Westcott House Foundation. The Westcott House Foundation managed the extensive 5 year, $5.3 million restoration, the house was fully restored to its original glory in October 2005, when it officially opened to the public for guided tours.
