T. H. Pasley
Best known today for a curious 1848 book on mesmerism and clairvoyance, this elusive 19th-century writer seems to have ranged widely across science and natural philosophy. Little is firmly documented about his life, which only adds to the air of mystery around his work.

About the author
T. H. Pasley is an obscure nineteenth-century author whose surviving reputation rests mainly on The Philosophy Which Shows the Physiology of Mesmerism and Explains the Phenomenon of Clairvoyance (1848). Catalog and bookseller records also connect the name with works on natural philosophy and related scientific subjects, suggesting a writer interested in explaining unusual phenomena through broad physical theories.
A note in the U.S. National Archives' Founders Online identifies a T. H. Pasley who wrote to Thomas Jefferson in 1816 and says he was probably associated with the Corps of Royal Engineers at Chatham, England. The same note describes his publications as covering a wide variety of scientific topics. Because biographical information is so limited and the surviving records are sparse, details about his personal life remain uncertain.
That uncertainty is part of what makes Pasley interesting to modern readers. He stands as one of those fringe yet fascinating voices from the nineteenth century who wrote at the border of science, speculation, and popular wonder.
