History

Katten Muchin Rosenman traces its origins to partners including Richard S. Rosenman, Irwin B. Katten, and William D. Muchin, and its early growth involved engagements with Chicago institutions such as the Chicago Board of Trade and regional players tied to the Illinois Supreme Court and Cook County legal community. During the 1980s and 1990s the firm expanded through lateral hires and office openings, entering markets connected to the New York Stock Exchange, Nasdaq, and the national restructuring wave following the Savings and Loan crisis. In the 2000s Katten navigated legal developments related to the Sarbanes–Oxley Act, the aftermath of the Enron scandal, and evolving securities regulation under the U.S. Securities and Exchange Commission. More recently, the firm adapted to market shifts after the 2007–2008 financial crisis and participated in transactions influenced by regulatory frameworks such as the Dodd–Frank Wall Street Reform and Consumer Protection Act.
