- 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.

- The Mietz & Weiss Marine Oil Engines, 1905 - August Mietz and Carl Weiss formed their engine manufacturing company in 1894. Rudolph Diesel held tight patents over the ignition system for his engines, so Mietz and Weiss produced two-stroke, semi-diesel engines that depended on a hot bulb to vaporize oil before compression and ignition. This catalog from 1905 featured Mietz and Weiss engines designed for use in watercraft.
