Portrait of Oliver Evans. There are 2 possible identifications for this man. Oliver Evans (1755-1819) was an inventor whose greatest contribution was the high pressure steam engine. He was born in Delaware and died in New York. (http://www.pbs.org/wgbh/theymadeamerica/whomade/evans_hi.html) Alternatively, it could be Oliver Evans, Jr.""The names of New Harmony's star-studded scientists are well known; those of her inventors, rather less so: Oliver Evans, Jr., and Robert Henry Fauntleroy, to name just two. Evans and Fauntleroy were contemporaries; they were both married to women of distinguished ancestry and distantly related to each other through these marriages. They lived successively in the same house (at Evans' death Fauntleroy purchased the Harmonist frame building). They apparently worked together, for the designs and drawings of Evans ultimately became the possessions of Fauntleroy in whose personal papers they survived. Evans, youngest son of the inventor of high pressure engines, steam carriages, and milling systems, was influenced by the rich heritage of his father. He married Louisa, the eldest daughter of Joseph Neef, in 1827 and came to live in New Harmony. There he taught in the Owen Community schools, joined the Education Society, began operation of an iron foundry, manufactured cast plows, operated a sawmill, set up a grist mill to make use of his steam engine, and farmed."
