Sylvester H Roper reportedly built some ten steam carriages between 1860 and 1896.

There is a great deal of information on Roper, which has not been collected here. There is now enough material for a new book about Roper. Whoever writes this book should look at several other early steam carriages that were likely built by Roper but claimed by other so-called inventors.
