Who became the new chairmen of Standard Oil of New Jersey in 1960?

• A. John D. Rockefeller Sr.
• B. Henry Ford
• C. John D. Rockefeller Jr.
• D. Monroe Rathbone

Answer: (D)

In 1960, Standard Oil of New Jersey appointed Monroe Rathbone as its chairman, reflecting a move toward professional management in big firms during that era. The Rockefeller names listed—Sr. and Jr.—are tied to the company’s founding and early leadership, far earlier in its history, while Henry Ford is unrelated to this company. Rathbone’s chairmanship marks the transition to a non-family, executive-led leadership style that many large corporations adopted as they grew and diversified. Standard Oil of New Jersey continued on as Exxon after later restructurings, with governance increasingly led by seasoned corporate managers.
