Description

“After a brief survey of the work of Morland, Leibniz, Poleni, Leupold, and Pascal, Gersten states that his work was motivated by the Leibniz machine, but was developed independently of both the mechanisms of Leibniz and Pascal. Then gives an extremely detailed description of his machine, its inner mechanism, and method of use” (Randell).
