Dover 

Founded in 1955 by George Ohrstrom, Dover has become an industrial behemoth through the acquisition of dozens of esteemed brands. The company is organized into five segments through which it designs and manufactures highly engineered components, such as vehicle repair, factory automation, welding, aerospace, fuel dispensing, printing, liquid handling, refrigeration, and can-making equipment. It has operations around the globe but generates over half of its revenue in the United States.
