Talk:John Southern (engineer)

21:53, 8 February 2024 (UTC)Andrew Macklin (talk) It's more accurate to say that Southern, with Watt, invented the Indicator; that's what they called their device. The "indicator diagram" was the output of the device. Welcome comments before submitting significant modifications to the entry (and possibly the entry for Indicator Diagram).
