"Clorion" was a pseudonym used by the creator of this anatomical sketchbook in New Harmony, Indiana, in 1830. It was apparently copied from The Medical Adviser and Domestic Physician, possibly a journal, published in London in 1830; unfortunately, no extant copies of the printed version can be located.
Harmonie, Indiana, was founded in 1814 when Separatists from the German Lutheran Church left their home in Harmonie, Pennsylvania, led by charismatic religious leader Johann Georg Rapp. In 1825, these settlers left to found the town of Economy, Pennsylvania, selling the Indiana site to social reformer Robert Owen, who founded a utopian communitarian settlement there called New Harmony.
A number of important scientists and naturalists of the time lived in or visited New Harmony in the following decades, including Thomas Say, Charles-Alexandre Lesueur, Constantine Samuel Rafinesque, and Gerard Troost. Among them was the young scientist, David Dale Owen (1807-1860), a son of Robert Owen who moved to New Harmony from Scotland in 1825. He attended medical classes in Switzerland before his arrival and later obtained a medical degree from Cincinnati's Ohio Medical College. He was most noted as a geologist, however, performing some of the first and most important geological surveys of the American Midwest. While it is not certain that Owen was "Clorion," it seems plausible, and further investigation is certainly warranted.
