Join us as we uncover the story of an S&P 500 company that has not only shaped industries but also set a benchmark for operational excellence and strategic growth on a global scale.

The story of Illinois Tool Works officially begins in Chicago in 1912, though its roots stretch back a bit further into the enterprising spirit of the Smith family. Byron L. Smith, a prominent Chicago financier and founder of the Northern Trust Company, was a man with a keen eye for opportunity. In late 1911, he placed an advertisement in The Economist seeking to invest capital in a "high class business (manufacturing preferred) in or near Chicago." He was looking for something with real potential, and he wasn't about to jump at the first offer that came his way.

This advertisement caught the attention of a small group of inventors and tool-and-die industry veterans from Rockford, Illinois: Frank W. Englund, Paul B. Goddard, Oscar T. Hegg, and Carl G. Olson. They had an idea to improve gear grinding technology, a crucial process for the burgeoning industrial landscape of the early 20th century. After some initial reluctance and negotiations, Smith, backed by his wealthy and influential family, recognized the promise in their proposal and agreed to invest. This pivotal partnership marked the birth of Illinois Tool Works Inc.

Illinois Tool Works, or ITW as it would become widely known, officially opened its doors in 1912, setting up shop at the corner of Huron and Franklin Streets in Chicago. The company’s initial focus was on producing metal-cutting tools, including cutters, hobs, and jigs, primarily serving the expanding Midwestern industries. The timing was fortuitous, as the region was a hotbed of manufacturing, with railroads and the Great Lakes transforming Chicago into a vital transportation and industrial hub.

The fledgling company quickly found its footing. Demand for its products grew rapidly, necessitating additional space and employees to keep pace. This early success was a testament to the founders' hard work, dedication, and an inherent drive to innovate. Remarkably, ITW even managed to turn a profit of $42.94 in its very first year of operation, an auspicious start for any new venture.

Byron L. Smith's son, Harold C. Smith, played a significant role in guiding the firm in these formative years. After Byron Smith's passing in 1914, Harold C. Smith assumed the leadership of the company. He continued to steer ITW with a conservative financial approach, a characteristic that would define the company for decades. Harold C. Smith prioritized maintaining cash reserves and avoided debt, a strategy that proved particularly beneficial as the world teetered on the brink of a global conflict.

World War I, which erupted in 1914 and drew the United States into the fray in 1917, significantly boosted ITW's profits. The increased demand for manufactured goods, particularly those related to automotive and truck components for the war effort, fueled the company's growth. This period solidified ITW's position as a reliable supplier of high-quality industrial tools.

Even in these early days, the company’s leadership understood that long-term success wouldn't come from simply mass-producing common items. Instead, they focused on inventing and building specialized tools tailored to customer needs, a strategy that often involved securing patents. This customer-centric approach to innovation became a cornerstone of ITW's philosophy, setting the stage for future groundbreaking developments.

As the 1920s dawned, the automotive industry was revving up, presenting both challenges and immense opportunities. The mass production of automobiles demanded efficient and reliable fastening solutions, an area where existing technology often fell short. It was in this environment that ITW made a pivotal move that would significantly diversify its product line and propel it into a new industry niche.

In 1923, ITW made its first major acquisition, acquiring the Shakeproof Screw and Nut Lock Company. This acquisition brought with it a "blockbuster" product: the Shakeproof lock washer, the first twisted-tooth lock washer. This innovative fastener was designed to generate tension, preventing bolts and screws from loosening due to vibration and wear, a common problem in the rapidly evolving automotive industry. The unique helical shape and split design of these lock washers made them highly effective anti-loosening components.

The Shakeproof fastener quickly became an industry leader. Though each individual washer sold for less than a cent, the sheer volume of sales generated substantial profits for ITW. The company’s acquisition of Shakeproof effectively brought it into the profitable realm of industrial fasteners, a market it would come to dominate. The Shakeproof division eventually became ITW's largest, offering a full line of related items, including preassembled washers and screws, and thread-cutting screws.

The success of the Shakeproof lock washer underscored ITW's growing understanding of specialized, engineered solutions. The company wasn't just making tools; it was solving critical problems for its customers. This era also saw the emergence of "Customer Application Engineering," pioneered by Jack Gribbie, a sales manager at Shakeproof. Gribbie recognized that countless new applications for Shakeproof fasteners existed in industries that hadn't yet adopted them. His pioneering work involved actively seeking out these new applications and designing solutions tailored to specific customer needs, a practice that became fundamental to ITW's innovative culture.

By the mid-1920s, Illinois Tool Works had firmly established itself as a significant player in American industry. It had successfully transitioned from a nascent enterprise focused solely on metal-cutting tools to a diversified manufacturer with a strong presence in the booming industrial fastener market. The foundational years, marked by shrewd financial management, a commitment to innovation, and the strategic acquisition of game-changing products like the Shakeproof lock washer, had laid a robust groundwork for the decades of growth and diversification that were yet to come. The principles of customer-backed innovation and specialized product development, nascent in this period, would continue to evolve and define the company's trajectory, propelling it towards its future as a global industrial powerhouse.
