First printing of Maxwell's rare important work "On Governors", marking the beginning of feedback theory.
Although forms of feedback systems were known and used for centuries, it was not until James Watt's invention of the centrifugal governor in 1788, that such devices were seen as an indispensable feature of modern science, and scientists began to understand the necessity of formulating a mathematical theory for such control systems. By developing models covering negative feedback, stability, and damping, Maxwell, in 1868, became the first to produce an effective theoretical and mathematical analysis of a control system. "On Governors" is now recognized as "the first significant paper on feed-back mechanisms" and one of the foundational documents of cybernetics.
