A Heilmann Horseless Carriage

This unusual machine consisted of an electric tractor unit coupled to a conventional horse drawn carriage. The electric tractor unit was designed by J. J. Heilmann, who also designed a very promising steam electric railway locomotive that used high speed steam reciprocating engines to power a generator but had the disadvantage that it required a crew of four, making it commercialy unviable.

The photograph was taken from Just a car guy (who found it at Philippe Boursin's French website HISTOIRE DE LA VOITURE ELECTRIQUE), which I found via Hemmings Daily.
