1884 In a letter to the editor of The Electrical World:
"The Lumley Dynamo-Electric Machine. SIR. In your issue of Nov. 8th I notice an article headed “The Kind of Plant Wanted.” Permit me to say that the so-called Phoenix dynamo made by Patterson and Cooper of London, England is no other than the Lumley machine ..."
Another sources suggest that Lumley may have been American.
