Which founder partnered with Rockefeller in 1867 and later founded two Florida cities?

• A. John D. Rockefeller
• B. Henry Flagler
• C. Henry Ford
• D. Cornelius Vanderbilt

Answer: (B)

Henry Flagler. He teamed up with John D. Rockefeller in 1867, forming a partnership that helped create Standard Oil, a dominant force in oil refining. Flagler later used his wealth to transform Florida’s east coast, building railways and luxury hotels that spurred growth and settlement, effectively founding two Florida cities along that corridor—Palm Beach and Miami. This combination of a key business partnership with Rockefeller and significant Florida development is what makes Flagler the correct answer.
