Which American investor sought permission to search for oil in the Cayman Islands in 1920?

Hiram Hixon is known for seeking permission to explore for oil in the Cayman Islands in the 1920s. During this time, there was a growing interest in the potential for oil discovery, which could lead to significant economic benefits for various regions. Hixon's exploration efforts were part of a broader trend of investors looking for untapped resources outside of the traditional oil-producing areas.

The other figures mentioned, while notable in their own rights—John D. Rockefeller for his pivotal role in establishing the American oil industry, Henry Ford for revolutionizing the automobile manufacturing process, and Isidore Schlesinger for his involvement in various business ventures—are not connected to oil exploration efforts in the Cayman Islands during the 1920s. This distinction highlights Hixon's unique role in the context of Cayman Islands history regarding oil exploration.
