Conceived in the early years of World War II as a plan to bury four fuel containers horizontally in a hillside at the U.S. Navy facility at Pearl Harbor, Hawaii, the Red Hill Underground Fuel Storage Facility ultimately encompassed the design and construction of 20 vertical storage tanks - each large enough to contain a 20-story building - buried in the volcanic hillside and connected by tunnels to a harbor-side pumping station more than two-and-a-half miles away.

The Kamehameha V Post Office is the oldest surviving public building in the U.S. constructed with reinforced concrete. The success of this early structure helped establish the value of reinforced concrete as a durable construction material.
Brickmaker J.G. Osborne was chosen to provide design and construction. He immigrated to Hawaii from Yorkshire, England, and was aware of the recent development of Portland cement and its expanding use in Europe. It is believed that the leaders of Hawaii were anxious to adopt British skills, which influenced their selection of Osborne.

Commercial pineapple production began in Hawaii about 1890. Fruit was hand-peeled and sliced to match can sizes for export. In 1911 James D. Dole hired Henry G. Ginaca to design a machine to automate the process. As fruit dropped through the Ginaca machine, a cylinder was cut to proper diameter, trimmed top and bottom, and cored. This machine more than tripled production, making pineapple Hawaii's second largest crop.
