(The seventh volume of American Conchology was published in Philadelphia.) Lucy Sistare Say was an apprentice at Fretageot's Pestalozzian school and a former student of Lesueur in Philadelphia before coming to New Harmony aboard the Philanthropist to teach needlework and drawing. En route to Indiana, Sistare met Thomas Say and the two were married on January 4, 1827, prior to their arrival at New Harmony. An accomplished artist, Say illustrated and hand-colored 66 of the 68 illustrations in American Conchology, her husband's multi-volume work on mollusks. Following Thomas Say's death in 1834, she moved to New York, trained to become an engraver, and worked to complete and publish the final volume of American Conchology.

In 1841 she became the first female member of the Academy of Natural Sciences of Philadelphia.<ref name=LucySay German-American folk artist Jacob Maentel (c. 1763–1863) lived in New Harmony from 1836 until his death.
