The story
Dorsey was founded in 1912 by William Lancaster, a director of First National Bank of Minneapolis (now part of U.S. Bank), and David F. Simpson, a justice of the Minnesota Supreme Court. The following year, they hired James Dorsey as their first associate. Dorsey left the firm in the 1920s to become an investment banker, but returned to the firm a few years after the 1929 stock market crash. Dorsey led the firm until his death in 1959. The name of the firm continued to change for most of its history, until it was shortened into its current, permanent name in 1981.
The firm has also endowed the Dorsey and Whitney Professor of Law at the University of Minnesota Law School.
