Following Ron Roizen's suggestion, I summarize here my private post to Carolyn Carter Johnson who is researching the career of her great great grandfather "Dr." John Switzer Cunningham as a temperance lecturer in the USA and England for the Independent Order of Good Templars. Predictably I suggested that for background she might care to read the introduction and first chapter of my book, Temperance & Racism: John Bull, Johnny Reb, and the Good Templars (Kentucky, 1996). I also pointed out that the Good Templars originated in the early 1850s, so the lecture that Cunningham made in Philadelphia in the 1840s could not have been under Good Templar auspices. I also noted that many temperance lecturers worked the circuit on both sides of the Atlantic.
