- Alexanderson Radio Alternator, circa 1915 - This Alexanderson radio alternator rotated to generate a high-frequency alternating current--an essential component to early radio transmission. It was one of the first devices able to generate continuous radio waves, allowing sound to be transmitted by radio. These alternators were used for transoceanic communication during WWI, remaining in use until vacuum tube transmitters replaced them in the 1920s.

- Dr. Beard's Alternative Tonic & Laxative Bitters, 1870-1890 - Bitters is an herb-infused alcoholic mixture. Named for its bitter taste, the liquid was originally developed as a medicinal tonic to help soothe stomach complaints or other digestive disorders. During the late 19th and early 20th centuries, patent-medicine dealers bottled and sold the elixir. Americans purchased bitters in simple mold-blown bottles or ones shaped like drums, barrels, or cabins.

- Harry Miller: Engines and Cars, 1929 - Designer Harry Miller was one of the most influential figures in early American auto racing. He pioneered the use of front- and four-wheel-drive chassis, lightweight metals, and supercharged engines. Miller's innovative automobiles and engines dominated the Indianapolis 500 in the 1920s and 1930s. Miller-designed cars or engines won the race 14 times from 1922 to 1938.

- Thomas Edison Experimenting with Goldenrod as an Alternative Source of Rubber, Florida, 1929 - In the 1920s, Thomas Edison began his search for a home-grown source of rubber. The U.S. imported rubber from Southeast Asia and the East Indies and Edison wanted a ready source in case America's supply was cut off. Edison experimented with a variety of plants at his Fort Myers, Florida, and West Orange, New Jersey, laboratories. Goldenrod proved most promising.

- United States Patent No. 533,244 for Systems of Distribution by Alternating Currents, January 29, 1895 - Charles Steinmetz excelled at applying mathematical theory and scientific methods to practical engineering, helping define the role of "scientist-engineer" in the American electrical industry. Working at General Electric in the 1890s, Steinmetz developed influential theories on alternating currents and conducted breakthrough experiments on power loss. His innovations improved the efficiency of electrical power distribution over long distances.
