The story

Started as Donaldson Engineering, a small business built around Frank Donaldson's air intake filter invention (engine air cleaner). Frank Donaldson invented the air intake filter while repairing a tractor in Utah. The business was incorporated in 1915 by Donaldson, his parents and his siblings as Donaldson Company Inc.

In its first decade, Donaldson Company made two important moves; it acquired the Wilcox-Bennet air filter license and introduced the Simplex, a filter that also prevents engine damage. Deere & Company was the company's most important client during the first couple decades. The early 1930s brought additional prosperity when William Lowther joined the company and designed the NS Filter, a tractor performance enhancing filter invented by Frank Donaldson. The 1930’s were a transitional period, beginning with tough economic conditions in the United States which caused business from farmers to fall and subsequently forcing the company to contract in size. This was later followed by the sale of patents to influential investors provided the company with funds and market exposure needed to survive and grow (part of the agreement was that Donaldson Company produce the filters). World War II provided opportunities for the company to expand into aerospace and military hydraulic equipment and device filters. The 1950s were bittersweet. While the company gained market share, grew in size and went public in 1955, it was beset by employee strikes, the exodus of key employees (who started a new company to compete with Donaldson for market share) and IRS charges of hidden back taxes.

In the 1960s subsidiaries were established in Germany, South Africa, Britain, France, Australia and Benelux.
