Original Drawing of the 'Earth' BatteryDescription
This is a hand-drawn sketch, apparently by Lewis Latimer of an "Earth" Battery, an early experimental electrochemical device. The drawing depicts a glass jar containing a spherical metal component with two visible holes, connected to terminals at the top. The shading and fine detailing suggest this was a technical illustration meant for publication or documentation. A faint handwritten note at the bottom reads "Original drawing for cut," indicating that this was the source drawing for a printed engraving.Context
The Earth Battery was a type of electrochemical energy source that used soil or other natural materials to generate electrical power. These devices were part of 19th-century electrical experiments, particularly in telegraphy and early electrical systems. The sketch appears to be the basis for the printed engraving found in related newspaper or scientific publications, likely discussing alternative power sources in early electrical applications.Collection
