The San Jacinto Monument commemorates the decisive 1836 battle near the banks of the Buffalo Bayou and the San Jacinto River that allowed Texas to win independence from Mexico. It is the world's tallest monument, rising 15 feet higher than the Washington Monument.

In 1936, Daughters and Sons of the Republic of Texas led lobbying efforts to allocate funds for a monument that would mark the importance of the Battle of San Jacinto. Ground was broken on April 21, 1936 - 100 years to the day after the victorious battle.

Dunlap's Creek Bridge

Society: ASCE Main Category: Civil Sub Category: Bridges Era: 1930-1939 DateCreated: 1939 Dunlap's Creek Brownsville State: PA Zip: 15417 Country: USA Website: http://www.asce.org/Project/Dunlap-s-Creek-Bridge/ Creator: Delafield, Richard , U.S. Army Corps of Engineers

Not only was Dunlap's Creek Bridge the first cast-iron bridge in America, it was the first metal bridge anywhere to use what its builder, Capt. Richard Delafield, U.S. Army Corps of Engineers, described as "standardized, interchangeable, manufactured parts." The bridge was built as part of the federal government's effort to make repairs on the National Road before handing authority over to the states. Dunlap's Creek at Brownsville was an especially troublesome crossing, having destroyed three previous bridges since 1801.

The David Taylor Model Basin is among the largest facilities of its kind in the world, containing a shallow water basin, a deep water basin and a high-speed basin. Using its sophisticated combination of towing carriages, wave makers, and measuring equipment, engineers are able to determine the sea-keeping qualities and propulsion characteristics of ship and craft models up to 40 feet in length. Since it became operational, the facility has provided key support in the development of naval architecture for the Navy, the Coast Guard, the Maritime Administration, and the maritime industry.

Atanasoff-Berry Computer

Society: IEEE Main Category: Consumer Electronics Sub Category: Computers and Information Processing Era: 1930-1939 DateCreated: 1939 Ames State: IA Zip: Country: USA Website: http://www.ieeeghn.org/wiki/index.php/Milestones:Atanasoff-Berry_Computer,_1939 Creator: Atanasoff, Vincent John, Berry, Clifford E.

John Vincent Atanasoff conceived basic design principles for the first electronic-digital computer in the winter of 1937 and, assisted by his graduate student, Clifford E. Berry, constructed a prototype here in October 1939. It used binary numbers, direct logic for calculation, and a regenerative memory. It embodied concepts that would be central to the future development of computers.

Sikorsky VS-300 Helicopter

First practical US helicopter, pioneering the single-main-rotor concept

Society: ASME Main Category: Mechanical Sub Category: Air and Space Transportation Era: 1930-1939 DateCreated: 1939 Henry Ford Museum Dearborn State: MI Zip: 48214 Country: USA Website: http://www.asme.org/about-asme/history/landmarks/topics-a-l/air-and-space-transportation/-95-sikorsky-vs-300-helicopter-%281939%29, https://www.asme.org/getmedia/b997b811-c5c4-44e3-87d3-239bda559734/95-Sikorsky-VS-300-Helicopter.aspx Creator: Sikorsky, Igor I.

America's first practical helicopter, it pioneered the single main rotor concept that became the predominant helicopter configuration throughout the world. The principles that were developed and demonstrated by the VS-300 had direct application in the design of the early mass-production helicopter, marking the beginning of the world's rotorcraft industry.

The initial flight of the VS-300 was piloted by its designer, Igor I. Sikorsky (1889-1972), on September 14, 1939, in Stratford, Connecticut.
