1935

Bell Aircraft, founded in 1935 by Lawrence Dale “Larry” Bell, based its primary manufacturing facility in Wheatfield, New York, where several important aircraft were designed and produced. During the World War II era, the plant produced the P-39 Airacobra and the P-63 Kingcobra fighters. The P-39 was used to great effect by the Soviet Air Force, with the highest number of individual kills recorded by any U.S.-produced fighter aircraft during the war. The plant also designed and manufactured the P-59A Airacomet, the first U.S.

"It remains today one of the great bridge engineering accomplishments for railway and highway bridges built in the country."

During the 1920s, Edwin A. Link was employed in his father's organ building and repair business. He obtained his pilot's license in 1927 and became convinced that a mechanical device could be built as an inexpensive method to teach basic piloting. Link received three patents on his flight trainer (No. 1,825,462, March 12, 1930; No. 2,244,464, June 3, 1941; and No. 2,358,016, Sept. 12, 1944).

The Port Washington Power Plant of the Wisconsin Electric Company was the most thermally efficient steam power plant in the world for many years following its opening in 1935. Its design reflected the cumulative experience of the utility's engineers in burning pulverized coal at the Oneida Street Plant and the Lakeside Station in Milwaukee.

In 1918, the U.S. Reclamation Service's director and chief engineer Arthur P. Davis proposed a dam of unprecedented height to control the devastating floods on the Colorado River, generate hydroelectric power, and store the river's ample waters for irrigation and other uses.

Established in 1935 as the Valparaiso Bombing and Gunnery Base, the base supported the U.S. Army Air Corps, the predecessor to the U.S. Air Force, as its primary facility for training new pilots in bombing and gunnery tactics. It also served as a test facility for aircraft, aircraft armament, air-delivered munitions and other aircraft systems. The base was renamed Eglin Field in 1937 in honor of Air Corps aviator Lt. Col. Frederick I. Eglin, who trained pilots during World War I, and who had recently died in an aircraft accident. After Congress created the U.S.
