      abstract = {V. C. Duclos and wife with group, sitting next to some  sort of mechanical device. Duclos is known to have been  involved with, as an officer or a trustee, the Posey County  Agricultural Society in 1872, and to hold a patent (no.  84,097) on a plow as reported by the Commissioner of  Patents in 1869. The following piece of information may or  may not relate to this photograph:""Marie Duclos was born  in France and at some unknown date married Joseph  Fretageot. She met William Maclure in Paris in 1819, not  long after he had become President of the Academy of  Natural Sciences of Philadelphia. Madame Fretageot moved to  Philadelphia in 1821, where she established a school and,  like Maclure, became interested in Robert Owen's principles  for social reform. In 1826 both Maclure and Madame  Fretageot moved to New Harmony to join in Robert Owen's  experimental community. For reasons of health, Maclure  resided there only a short time, but Madame Fretageot  remained and managed his continuing financial support of  science and education in New Harmony?against great odds. In  February, 1833 she joined Maclure in Mexico City, and that  August, she died there."  (https://faculty.evansville.edu/ck6/bstud/fret.html) The  Marie described here is thought to be an aunt to this man.  No further information could be found, so anything other  than the uniqueness of the name in New Harmony is but  educated speculation.},
