Emerson was established in 1890 in St. Louis, Missouri, as Emerson Electric Manufacturing Co. by Civil War Union veteran John Wesley Emerson to manufacture electric motors using a patent owned by the Scottish-born brothers Charles and Alexander Meston. In 1892, it became the first to sell electric fans in the United States. It quickly expanded its product line to include electric sewing machines, electric dental drills, and power tools.

During World War II, under the leadership of Stuart Symington,[8] Emerson became the world's largest manufacturer of airplane armament. Emerson ranked 52nd among United States corporations in the value of World War II military production contracts.[9]

In 1954, W.R. "Buck" Persons was named company president. Under his leadership, Emerson diversified its business by acquiring 36 companies. When he retired in 1973, the company had 82 plants, 31,000 employees and $800 million in sales.

In 1962, acquired United States Electrical Manufacturing Company as the U.S. Electrical Motors Division, including the brand U.S. Motors.[10] In 1968, it acquired the InSinkErator company.

Charles F. Knight served as CEO from 1973 to 2000, and was chairman from 1974 to 2004. His tenure was marked by the development of a rigorous planning process, new product and technology development, acquisitions and joint ventures, and international growth. David Farr succeeded him as chairman, who was also the CEO until 2021.

On December 15, 1999, Emerson Electric agreed to acquire Jordan Industries Inc.'s telecommunications equipment business for $440 million.[11]

In 2010, the U.S. Motors brand was sold to Nidec Motor Corporation.[10]

On April 1, 2020, Emerson acquired American Governor Company to boost its presence in the hydropower controls systems market.[15]



The company's leaders since the mid-20th century have been, respectively, W. R.

NBC Heroes lawsuitEdit

On October 2, 2006, Emerson filed suit in federal court against NBC regarding a scene that appeared in the pilot episode of the network's TV series Heroes. The scene depicted Claire Bennet reaching into an active garbage disposal, severely injuring her hand. Emerson's suit claims the scene "casts the disposer in an unsavory light, irreparably tarnishing the product" by suggesting that serious injuries will result "in the event consumers were to accidentally insert their hand into one."

Emerson asked for a ruling barring future broadcasts of the pilot and to block NBC from using any Emerson trademarks in the future.

On February 23, 2007, the case was dropped. NBC Universal and Emerson Electric settled the lawsuit outside of court.[27]
