A major advance in the history of computing occurred at the University of Pennsylvania in 1946 when engineers put the Electronic Numerical Integrator and Computer (ENIAC) into operation. Designed and constructed at the Moore School of Electrical Engineering under a U. S. Army contract during World War II, the ENIAC established the practicality of large scale, electronic digital computers and strongly influenced the development of the modern, stored-program, general-purpose computer.

Dr. Takeshi Takei, the professor at the Tokyo Institute of Technology, discovered that composite oxides containing zinc and iron have distinguished magnetic properties. In 1930, Prof. Takei submitted a paper on his work to Japanese Electro-chemical Society and also presented a paper at 57th General Meeting of American Electrochemical Society in St. Louis. That same year, Prof. Takei applied a patent for his discovery, which was granted in 1932(Japan PAT-98844). Tokyo Denki Kagaku Kogyo (now TDK Corporation) was founded in 1935 to commercialize this newly invented ferrite cores.

The "Alligator" amphibian tractor is the progenitor of all amphibian assault vehicles used since 1941, a pioneer venture both in its design and the materials used in its construction. Donald Roebling, a grandson of Colonel Washington Roebling (designer of the Brooklyn Bridge), built an amphibian tractor to rescue victims of Florida's devastating hurricanes (particularly those in 1926, 1928, and 1932 that hit southern Florida).

Alaska Highway

The Alaska Highway, initially called the Alaskan-Canadian (Alcan) Military Highway, provided an essential transportation link to the Yukon and Alaska during World War II. It begins at the junction with several Canadian highways in Dawson Creek, British Columbia and runs to Delta Junction, Alaska, via Whitehorse, Yukon. After the shock of Pearl Harbor, the Alaska Highway was a first step in America's defense strategy -- a vital military supply line during the war. Over ten thousand Army Engineers were rushed to the far Northwest.
