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, 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] Symington went on to become the first United States Secretary of the Air Force from 1947-1950, a Democratic U.S. Senator from Missouri from 1953-1976, and a candidate for the Presidency of the United States in 1960.

In 1954, W.R. "Buck" Persons was named company president. Under his leadership, Emerson diversified its business portfolio 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, acquired InSinkErator company.

Charles F. Knight served as CEO from 1973 to 2000, and was chairman from 1974 to 2004. His tenure was marked by development of a rigorous planning process, new product and technology development, acquisitions and joint ventures, and international growth.

David Farr has served as CEO since 2000 and as chairman since 2004.

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

In 2010, U.S. MOTORS® brand sold to Nidec Motor Corporation.[10]

On July 26, 2011, Emerson announced it would locate its Latin America headquarters in Sunrise, Florida.[12]

On December 1, 2016, Platinum Equity acquired Emerson Network Power business unit and rebranded it Vertiv. The acquisition included the brands: Asco, Chloride, Liebert, Netsure, and Trellis.[13]

In July 2018, Emerson completed the purchase of Textron Tools and Test Businesses for $810 million (Including Greenlee, Klauke, HD Electric and Sherman + Reilly).[14]

NBC Heroes lawsuit

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.[20]
