Born in Dornach, Alsace, France in the late 1800s, he was sponsored by a textile mill in Adams, Massachusetts to come to this country as a photoengraver in early 1900. He later became a draftsman for the General Electric Company in Pittsfield, Massachusetts.
Jenny had one man shows at the Berkshire Museum in Pittsfield, taught art at the museum and in Adams Massachusetts and at his home in Pittsfield. He was also an accomplished calligrapher. His work appears in many Norman Rockwell covers for the Saturday Evening Post. Most of his landscapes are of local scenes in Massachusetts.
He was also a draftsman on test equipment for the Manhattan Project, the building of the first atomic bomb. He accomplished all these things with an eighth grade education and a deep love of art for arts sake. In his later years he taught art at Lanesboro Elementary School in Lanesboro, Massachsetts.
