Using the Davy Letters Database

Over the years 1815-17, a public controversy ensued over who should be given the credit for the invention of the safety lamp.

The controversy involved Davy, George Stephenson, and William Reid Clanny – all of whom had invented safety lamps around this time – and their various advocates and allies.

Davy and Stephenson never met. The controversy between them was conducted primarily by letters, both public and private. Just as Davy and Stephenson never met, neither did they ever correspond directly.
