Thompson and Thomas published both Tom Brown books at the turn of the century.
Not much is known about this publishing house.
Charles C. Thompson (1867-1914) was born in Albion, Wisconsin. He was involved in the book publishing/selling business in Rutland, Illinois prior to
becoming a named partner in the Thompson and Thomas publishing house in 1897. I have seen a book as early as 1890 with the C. C. Thompson/Rutland, Illinois imprint. The firm name was changed to Charles C. Thompson and Co. in 1909. A short bout of pneumonia was the
cause of Thompson's demise.
I have no significant information about the other named partner, C. E. Thomas. There is evidence that Thomas published titles on his own
imprint in the late teens.
It appears that they were at 267 Wabash from the late 1890's until about 1903 when they moved to 338 Wabash (Chicago).
