The Business: Milton L. Rock, Ph.D. (1921-2018) joined Edward N. Hay in 1949 to establish a compensation and human resources consulting firm and became the Hay Groupâs managing partner. Miltâs son, Robert H. Rock, joined the firm and worked alongside him. At the time of its sale in 1984, the Hay Group had 2,000 consultants and 90 offices in about 25 countries.
In 1980, Hay acquired a small company that published a quarterly journal, Directors & Boards. The governance journal helped promote Hayâs services to top executives.
