An Eulogium intended to perpetuate the memory of David Rittenhous, late President of the American Philosophical Society

42p. Disbound. David Rittenhouse (1732-1796) "The preeminent American scientist of his age, David Rittenhouse was at once an internationally famed astronomer, master craftsman of scientific instruments, and surveyor. His mechanical models of the solar system, precision clocks, surveyor's theodolites, compasses, and optical lenses were of the highest order available in the world. Although he received little formal education and was a man of ordinary means, his genius was a primary force of colonial American achievements in science, known as the Age of Enlightenment." [Rittenhouse Astronomical Society website] The eulogy was authored by Benjamin Rush, (1746-1813) an American revolutionary, a Founding Father of the United States and signatory to the U.S. Declaration of Independence. Scattered foxing though mostly on the title page and some of the preliminaries.
