First Edition. Benzenberg, a German astronomer, was one of a number of scientists at the turn of the nineteenth century who conducted falling-body experiments to demonstrate the earth’s rotation and show the accuracy (or lack thereof) of theoretical predictions regarding the earth’s motion. Benzenberg’s first experiments were performed in 1802 from a church steeple in Hamburg (illustrated in the frontispiece); he followed these in 1804 with experiments conducted in a mine shaft. Benzenberg was responding in part to the work of Italian physicist Giovanni Baptista Guglielmini (1763-1817), who published his experimental research on the earth’s rotation in 1789 and 1792.
