EDITORS COMMENTS
This engraving captures a piece of history from the 19th century - a double-needle telegraph used in the House of Parliament. The intricate details showcase how operators would manipulate the instrument using two handles at the bottom, while conventional signals were indicated by single and combined movements of the galvanometer needles. The alphabet letters are clearly displayed, highlighting the communication capabilities of this innovative device.
Displayed at the International Electric Exhibition at the Crystal Palace in 1882, this engraving provides a glimpse into Victorian London and the advancements in electrical communication during that era. The alarm bell housed on the casing was used to signal the beginning of a message, adding an element of urgency to each transmission.
As you study this print closely, you can almost imagine the operator diligently working to send important messages back and forth within the walls of Parliament. The fusion of technology and communication is beautifully illustrated in this engraving, serving as a reminder of how far we have come in our methods of connecting with one another. This historical artifact is not just a visual representation but also a testament to human ingenuity and progress over time.
