A Crucial Step In The Evolution Of Modern Animal Agriculture Was The Development Of Mechanical Ventilation Methods For Animal Housing. Air Inlets Are Pivotal To Good Ventilation. In 1948 William F. Millier, Working At Cornell University Under The Direction Of Professor Clesson Turner, Tested And Published The Concept Of The Slotted Inlet. Professor Turner And Others At Cornell University Subsequently Continued To Develop Slotted Inlet Systems And Systematize Design Methods.

In the mid 1930's, the USDA Soil Conservation Service (SCS) realized the importance of hydrologic processes on agricultural fields and watersheds and determining their impact on soil erosion, floods, water resources, and the agricultural economy. In response, the SCS Hydrologic Division established experimental watersheds in Coshocton, Ohio, Hastings, Nebraska, and Riesel, Texas, and operated them until 1954 when the watersheds were transferred to the newly created Agricultural Research Service (ARS).

The first laser grade control was developed by agricultural engineers James Fouss and Norman Fausey of USDA's Agricultural Research Service at The Ohio State University in the mid-1960's. That system controlled the precise depth and grade of subsurface drains by regulating trenching and plow-type drainage machines. Photo cells mounted on the drainage machine automatically raised and lowered the digging device, keeping the cells centered on a laser beam set to the desired elevation and grade.

In 1926, Ives Hall, the original Agricultural Engineering Building at The Ohio State University, Columbus, was designated as ASAE's first engineering landmark in honor of department founder and 18th president of ASAE Fredrick Walter Ives. Frederick W. Ives 1884 - 1924.
Ives Hall was on the corner of Neil and Woodruff Avenues from 1926 - 2002. This display has been constructed with brick from the original structure.

The Cincinnati Observatory, “The Birthplace of American Astronomy,” is the oldest professional observatory in the United States. Ormsby MacKnight Mitchel, the “Father of American Astronomy,” founded the observatory in 1842. John Quincy Adams laid the cornerstone for the observatory on Mt. Ida, later renamed Mt. Adams. The original Merz und Mahler 11-inch refractor telescope was put into service in 1845 and is still in use here today on Mount Lookout.

Lunken Field, now also known as Cincinnati Municipal Lunken Airport, opened in 1925 on ground purchased from the Cincinnati Polo Club. The nation’s largest municipal airport at the time, it attracted several aerospace enterprises, starting with early aviator J. Richard “Dixie” Davis, who established his barnstorming enterprise there in 1925. In 1928, several other firms established enterprises at the field – each making history.

On this 84-acre meadow in 1904 and 1905, the Wright Brothers successfully mastered the mechanics of controlled, powered, heavier-than-air flight. The brothers also built the world’s first airport here, and in 1910 the Wright Company School of Aviation established a flying school on the site and trained many of the world’s first pilots, including some of the first military pilots, such as Thomas DeWitt Milling.

DayGlo fluorescent pigments, a new class of pigments based on fluorescent dyes and polymeric materials, were developed between the 1930s and 1950s by scientists at Switzer Brothers, Inc. (now Day-Glo Color Corp.). These pigments absorb various light frequencies (visible and invisible to the human eye) and reemit them, producing intense visible colors that appear to glow, even in daylight.
