Anhydrous Ammonia Application Technology
Society: ASABE Main Category: Agricultural & Biological Sub Category: Chemical Era: 1930-1939 DateCreated: 1932 Delta Research and Extension Center Stoneville State: MS Zip: 38776 Country: USA Website: https://www.asabe.org/awards-landmarks/asabe-historic-landmarks/anhydrous-ammonia-application-technology-56.aspx Creator: Edwards, Felix, Smith, J. O., Andrews, W. B.

In 1932, J. O. Smith, Agricultural Engineer at Delta Branch Experiment Station in Stoneville, MS, attached a small anhydrous ammonia cylinder to a plow in such a manner that the NH3 was released in the soil.  The plow, a Georgia Stock, was pulled by a gray mule named Ike.  This was the first known use of anhydrous ammonia as a soil-applied crop fertilizer.  The crude apparatus and the anhydrous ammonia it applied provided a much needed source of nitrogen for the otherwise rich alluvial soils of the Mississippi Delta.

However because it is such a hazardous material and is difficult to apply, many farmers choose to hire third party businesses to store and apply the fertilizer. Era_date_from:
Charles Herty
Society: ACS Main Category: Chemical Sub Category: Industrial Advances Era: 1930s DateCreated: 1932 Herty Advanced Materials Development Center Savannah State: GA Zip: Country: USA Website: https://www.acs.org/content/acs/en/education/whatischemistry/landmarks/savannahpaper.html Creator: Herty, Charles Holmes

When Georgia chemist Charles Holmes Herty found a way to make quality paper from pine trees in 1932, he also founded an industry that brought much-needed jobs to the depression-crippled south. Paper producers had deemed the plentiful pine too gummy—until Herty's Savannah Pulp and Paper Laboratory wrote a new chapter in the ancient craft inspired by insects who built paper nests while dinosaurs roamed the earth. At its root, however, the papermaking process remained the same: the bonding of cellulose, a polymer whose long chains support plant cell walls.

Going-to-the-Sun Road
Society: ASCE Main Category: Civil Sub Category: Roads & Rails Era: 1930-1939 DateCreated: 1932 Going-To-The-Sun Rd West Glacier State: MT Zip: 59936 Country: USA Website: http://www.asce.org/project/going--to-the-sun-road/ Creator: Goodwin, George , Vint, Thomas Chalmers

Considered one of the world's most scenic mountain drives, the two-lane Going-To-The-Sun Road through Glacier National Park was the first major road to be constructed directly over high mountain terrain, proving that roads did not need to be limited to mountain passes.

Radio City Music Hall Hydraulically Actuated Stage
Society: ASME Main Category: Mechanical Sub Category: Era: 1930s DateCreated: 1932 Radio City Music Hall New York State: NY Zip: 10020 Country: USA Website: http://www.asme.org/about-asme/history/landmarks/topics-a-l/entertainment/-217-radio-city-music-hall-hydraulically-actuated Creator: Clark, Peter

The precision "choreographed" staging of Radio City Music Hall offers size and versatility, unlike any other. Built in 1932 by Peter Clark, its innovative elevator system is a forerunner of other stage designs (including the Metropolitan Opera House) as well as aircraft carrier systems built in World War II. These elevators can handle people, animals, props and scenery at variable speeds, delivering them to the stage or above and also dropping out of sight in front to reappear again in the back, just as effectively.
