Notes for Thomas SAY

Explorer, pioneering natural scientist, and a founder of the Academy of Natural Sciences in Philadelphia, Thomas Say (1787-1834) devoted his life to establishing the authority of American scientists to name and describe their native flora and fauna (until then, specimens were sent to Europe for that purpose). He was the first to name and describe for science the coyote, plains grey wolf, and swift fox in addition to several western birds and many amphibians. He ranks with William Bartram, Alexander Wilson, Thomas Nuttall, and John James Audubon as one of the great naturalists of early America.

Thomas Say, Bartram’s great-nephew, is generally considered the father of American conchology (the study of shells) and entomology (the study of insects) because of his important pioneering studies in both fields.(75) There is no doubt these were encouraged by William Bartram, who had dealt with both subjects in a cursory fashion in his own publications. In an 1818 expedition to Florida, Say, William Maclure (the father of American geology and the president of the Academy of Natural Sciences of Philadelphia), George Ord (author of American Zoology) and Titian R. Peale (son of artist/collector Charles Willson Peale) retraced Bartram’s travels.(76) Ironically, because of the rules of nomenclature, several of the insects and shells Bartram described and illustrated on his four-year southern trip are credited to Thomas Say, who first accurately named them in the scientifically recognized publications of the Academy of Natural Sciences. It is indeed likely that Bartram shared his great-nephew’s pride in rediscovery and publication.

Thomas Say (June 27, 1787 - October 10, 1834) was an American naturalist, entomologist, malacologist and crustaceologist. He was a taxonomist and is often considered to be the founder of descriptive entomology in the United States.
Thomas Say was born in Philadelphia into a prominent Quaker family. He was the great grandson of John Bartram, and the great-nephew of William Bartram, whom Say frequently visited as a boy with butterfly and beetle specimens.
Say became an apothecary in his native town, but his interests soon turned to nature and he became a self-taught naturalist. In 1812 he became a charter member and founder of the Academy of Natural Sciences of Philadelphia (ANSP).
In 1816 he met Charles Alexandre Lesueur (1778-1846), French naturalist, malacologist, and ichthyologist who became also a member and later curator of the Academy, between 1816 and 1824.
He began his work on American Entomology at the Academy. He began a tradition of expeditions to collect specimens of insects. These expeditions were not without risks : Indian attacks, dangers of the frontier, hazards of traveling in wild countryside.
In 1818 Say accompanied his friend William Maclure (1763-1840), president of the ANSP (1817-1840) and father of American geology, Gerhard Troost, a geologist, and others members of the Academy on an geological expedition to the off-shore islands of Georgia and Florida, then a Spanish colony.
In 1819-1820, Major Stephen Harriman Long led an exploration to the Rocky Mountains and the tributaries of the Missouri River with Thomas Say as zoologist. The official account of this expedition included the first descriptions of the Coyote, Swift Fox, Western Kingbird, Band-tailed Pigeon, Rock Wren, Say's Phoebe, Lesser Goldfinch, Lark Sparrow, Lazuli Bunting and Orange-crowned Warbler.
In 1823, Say served as chief zoologist in Long's expedition to the headwaters of the Mississippi River.

Thomas Say travelled on the famous "Boatload of Knowledge" to an utopian society experiment, the "New Harmony Settlement" in Indiana (1826-1834), a venture of Robert Owen. One of the passengers was Lucy Way Sistare, whom Say married secretly, near New Harmony, on January 4, 1827. She was an artist and illustrator of specimens (such as in the book 'American Conchology'), who later became the first female member of the Academy. He was accompanied by Maclure, Lesueur, Francis Neef, an educator, and Gerhard Troost. There he later met another naturalist, Constantine Samuel Rafinesque-Schmaltz (1783-1840).
In the settlement of New Harmony, Thomas Say carried on his monumental work describing insects and mollusks, leading to two classic works:

* American Entomology, or Descriptions of the Insects of North America, 3 volumes, Philadelphia, 1824-1828.
* American Conchology, or Descriptions of the Shells of North America Illustrated From Coloured Figures From Original Drawings Executed from Nature, Parts 1 - 6, New Harmony, 1830-1834; Part 7, Philadelphia, 1836.

During their years in New Harmony both Say and Lesueur experienced considerable difficulties. He was a modest and unassuming man, living frugally, like a hermit, abandoning commercial activities and devoting himself to his studies.
He died, apparently from typhoid fever, in New Harmony, Indiana, on 10 October 1834, only 47 years old.
Say described over 1,000 new species of beetles and over 400 species of insects of other orders. No single individual before had discovered more new species than him.
He was honored by naming several species after him, such as .

* Say's Mud Crab, Caribbean Mud Crab Dyspanopeus (Neopanope) sayi (Smith 1869)
* Lanceola sayana Bovallius 1885, an amphipod from the family Lanceolidae.
