This paper forms part of the proceedings of the 10th Annual Berle Symposium (2018), which focused on Adolf Berle and the world he influenced. He and Gardiner Means documented in The Modern Corporation and Private Property (1932) what they said was a separation of ownership and control in major American business enterprises. Berle and Means became sufficiently closely associated with the separation of ownership and control pattern for the large American public firm to be christened subsequently “the Berle-Means corporation”. This paper focuses on the “rise” of the Berle-Means corporation, considering in so doing why ownership became divorced from control in most of America’s biggest companies. It also assesses whether developments concerning institutional investors and shareholder activism have precipitated the “fall” of the Berle-Means corporation, meaning U.S. corporate governance is no longer characterized by a separation of ownership and control.
