Air conditioning

Willis Carrier

The “Father of Air Conditioning,” Willis Carrier’s invention gave rise to numerous industries that power our economy today. Manufacturing of everything from baked goods to wartime supplies was made possible by air conditioning. Air conditioning led directly to summer movie blockbusters as people came to cooled theaters to escape the heat. The precise control of temperature and humidity made possible by his invention even enabled shopping malls, transatlantic flight, and the computers and servers that power the Internet.


Thomas Edison.

Edison set up his lab with money he earned by improving the telegraph system for Western Union. He referred to it as an “invention factory.” During the first five years Menlo Park existed, Edison patented an invention almost every month. By the time he died, Edison held more than one thousand patents.

Gasoline powered automobile.

Charles and Frank Duryea.

There are many different types of automobiles - steam, electric, and gasoline - as well as countless styles. Exactly who invented the automobile is a matter of opinion. If we had to give credit to one inventor, it would probably be Karl Benz from Germany. Many suggest that he created the first true automobile in 1885/1886.

Type Writer.

Christopher Sholes

The first modern typewriter was designed by Christopher Sholes in 1868. He was a printer by trade, and familiar with the tedious, time-consuming process of typesetting. With help from two friends, Carlos Glidden and Samuel Soulé, he built his machine, which mimicked the appearance of typeset pages by impressing one inked character at a time onto paper. Sholes soon purchased his partners' shares in the invention, and then spent five more years trying to refine the rather cumbersome device.
