- Paper Horseshoe Filament Lamp Used at New Year's Eve Demonstration of the Edison Lighting System, 1879 - Thomas Edison created the first practical incandescent lamp in October 1879. As the news spread the public clamored to view this achievement. On New Year's Eve, thousands streamed into Menlo Park to see the first public display of Edison's electric light. Dozens of lights, like this surviving example, lit up the homes, buildings and streets around Menlo Park and Edison's laboratory.

- Patent Model of Edmondson's Circular Calculating Machine, 1883 - Mechanical calculators used gears, cogs, levers, and rotating drums to solve mathematical problems indirectly. While Edmondson's Circular Calculator was rugged and reliable, its "stepped drum" system required people to slide plates and levers, making it difficult to master and time-consuming to operate. By the late 19th century, improved adding machines became popular, helping to reduce the common errors of human calculation.
