The story
Corporation Service Company (CSC) was founded in 1899 by Christopher L. Ward and Otho Nowland, who was then the president of Equitable Guarantee & Trust Company. Using an initial investment from Nowland, Ward, and their associate Willard Jackson, they established The Delaware Incorporators’ Trust Company. A similar company was formed separately by Josiah P. Marvel, an attorney and then-leader of the American Bar Association, The Delaware Bar Association, and the Delaware State Chamber of Commerce.
In 1920, Ward and Marvel merged their respective companies to form the Corporation Service Company. Through the 1970s, CSC exclusively served Delaware business entities. WMB Holdings is the parent company of CSC.
CSC's Corporate Domains division provides services to various corporations, including Apple Inc., Alphabet Inc., Amazon, Twitter, Starbucks, Lego, Sony, Disney, Ford, BMW, Toyota, Vodafone.
The company raised capital through the sale of its subsidiary company, the Delaware Charter Guarantee & Trust Company, which it had acquired in 1977. During the September 11 attacks, the company had offices on the 87th floor of the World Trade Center's South Tower. All 60 employees present at the time of the attacks managed to evacuate the tower before the second plane struck. In 2017, CSC opened its new headquarters in Wilmington, Delaware and rebranded from "Corporation Service Company" to "CSC."
