Until 1900, the Chicago River drained into Lake Michigan, along with all the sewage from the city; and the Des Plaines River west of Chicago emptied into the Illinois River, which eventually flows to the Mississippi. Chicago residents drew their drinking water from polluted areas of the lake near the mouth of the Chicago River, leading to outbreaks of typhoid and other waterborne diseases.

Amos Eaton and Stephen Van Rensselaer founded the Rensselaer School for "the application of science to the common purposes of life" in 1824. Eaton had practiced surveying as a teenager building his own compass and chain and wrote an early book on surveying. Later he studied law before becoming interested in geology and agriculture. Stephen Van Rensselaer was the seventh patroon of Rensselaerwyck a track of land comprising most of the current Rensselaer, Albany and Columbia Counties in the State of New York.

Aircraft engines, considered unreliable during the first 20 years of aviation due to their need for liquid-cooling, heavy weight and other inconsistencies, were given a revolutionary boost with the development of Pratt & Whitney’s R-1340 Wasp Radial Engine in 1925.

When Robert G. LeTourneau started moving earth in 1919, he thought that land leveling should require only one man. In 1920, by installing a generator and electric motors, R.G. was able to control the scraper blade from the tractor seat while driving the tractor.
In June 1922, LeTourneau developed his “Mountain Mover” with a telescoping bowl. He incorporated a floor behind the cutting edge taken from his previous designs, and employed welding instead of riveting to save weight.

The oldest and most comprehensive collection of photographic and cinematic technology
In 1888, George Eastman created the Kodak camera, the first camera designed to use roll film. The camera's simplicity and user friendly mechanism revolutionized amateur snapshot photography and in 1892, he founded the Eastman Kodak Company, in Rochester, New York.

The first wave pool in North America to consistently generate 3-5 foot spilling waves suitable for surfing
Big Surf Waterpark uses 15 gates that empty water into a 2.5 acre lagoon with contours that replicate a natural beach. Waves are produced by pumping water to a pre-selected height and released through underwater gates. The water released breaks over a baffle (similar to a natural reef), forming one wave per cycle. Water is recirculated to the lagoon through pumps.

The workforce consisted of less than 100 men, yet they finished construction in just 94 days. Such speed was possible due to the elimination of scaffolding. Instead, iron rods were used to support construction of the trusses between the towers, and workers moved back and forth across the rods. A…
