In October 1925 thousands of New Yorkers viewed an exhibition at the John Wanamaker department store entitled “The Titan City, a Pictorial Prophesy of New York, 1926-2026.” They saw murals of a spectacular skyscraper metropolis, with colossal setback towers spaced at regular intervals and connected by multilevel transit systems, arcaded sidewalks, and pedestrian bridges at the upper floors.

WHEN I TELL PEOPLE WE’RE THE BRANNOCK Device Company, they just look at me,” Tim Follett says. “When I say we make the metal thing that measures your foot in the shoe store, they grin and say, ‘Oh, yeah!’” Follett is vice president of the Liverpool, New York, firm that makes that thing. “We may be the only company in the world whose sole product is a foot-measuring device,” he observes.

Beginning in 1924, Professor Hidetsugu Yagi and his assistant, Shintaro Uda, designed and constructed a sensitive and highly-directional antenna using closely-coupled parasitic elements. The antenna, which is effective in the higher-frequency ranges, has been important for radar, television, and amateur radio.
The antenna system, using a driven element with closely coupled parasitics (usually a reflector and one or more directors) for short-wave work, was first described by S. Uda, a professor at Tohuku University in Japan, in 1926, in the IEEJ (Japan). A colleague, Professor H.

Professor Kenjiro Takayanagi started his research program in television at Hamamatsu Technical College (now Shizuoka University) in 1924. He transmitted an image of the Japanese character イ(i) on a cathode-ray tube on 25 December 1926 and broadcast video over an electronic television system in 1935. His work, patents, articles, and teaching helped lay the foundation for the rise of Japanese television and related industries to global leadership.
The milestone plaque may be viewed at the site of the research at Hamamatsu Technical College (now Shizuoka University).

In 1915, a tropical storm dropped nearly 11 inches of rain on St. Louis in just 17 hours, causing a devastating flood. Claiming 11 lives and the homes of 1,025 families, the flood focused public and government attention onto the problems of the river.

The tower was designed to rest on a continuous reinforced concrete mat, 4 feet thick, with the base of the slab 24 feet below street level.
What makes the Texas Commerce Bank Building revolutionary in the civil engineering world is not so much the building itself, but its foundation. Initial studies for the type of foundation to be used began in the fall of 1927. William E. Simpson, the building's chief structural engineer, suggested using a mat foundation, something new for Houston's multistory buildings.

Wind tunnel testing of aircraft models is essential to determine aerodynamic parameters such as lift and drag. The 5-foot Wright Field wind tunnel is an early example of the modern wind tunnel, well known from the early 1920s to the late 1950s for its contributions to research and the development of nearly every major aircraft and associated hardware used by the US Air Force and its predecessor, the Army Air Service.

The first Zuiderzee Enclosure Dam ran from North Holland to the island of Wieringen, successfully barring the sea for over 50 years and protecting a large area north of Amsterdam. The total Zuiderzee project was the largest land reclamation effort in the Netherlands, developed over a period of about 80 years, beginning in 1918 and reaching completion in 1996. The huge dyke/dam was considered one of the greatest engineering feats of its time.

This research and development complex was established by the founders of Universal Oil Products (later named UOP) to develop key products for the oil-refining industry. The processes created here profoundly affected the refining, treatment and conversion of crude oil and the development of the petroleum and petrochemical industries. Conceived as a combination of quiet academic retreat and industrial plant, Riverside attracted many of the world's leading petroleum scientists and a dedicated support team. Between 1921 and 1955, Riverside research resulted in 8,790 U.S. and foreign patents.
