McKinsey & Company Corporate Office

James McKinsey founded McKinsey & Company in Chicago in 1926 as James O. McKinsey & Company. He was a professor at the University of Chicago’s Booth School of Business. He is considered the father of managerial accounting.

In the beginning, the firm had an accounting practice and a management practice, which were separated in 1937.

In 1990 the firm established a think tank on globalization, corporate strategy, and governance called the McKinsey Global Institute.

Since 2000 McKinsey has focused on expansion to Asia and developing practices focused on the public and social sectors.
