Thomas Say

Say became a friend of Maclure when he looked after the Museum of Natural Sciences in Philadelphia, and accompanied him on an expedition to Georgia and Florida. He’d met Lesueur in Philadelphia; they were later members of Maclure and Owen’s famous ‘Boatload of Knowledge’ to New Harmony (Neef joined along the way), and stayed friends for life; Say living frugally, Lesueur working unpaid. Peale (as artist) knew Say (as zoologist) on an expedition up the Missouri, and went on to provide the illustrations for Say’s seminal work on American entomology.
