A Telescope Mount that Failed

What is it about?

Failure is an essential element of all scientific endeavors. However, dead ends, negative outcomes, and technical flaws are seldom reflected in published works, whether they be scientific papers or communications intended for a broader audience. This paper examines the so-called Herschel Telescope, built for the Royal Swedish Academy of Sciences in the late eighteenth century. Now a museum exhibit often used to illustrate or celebrate scientific progress, the instrument was, in its time, a complete failure, used only once under the stars. The mirror, cast and polished by the renowned William Herschel, was not the issue. The problem lay in the mount, constructed by an inexperienced Swedish instrument maker who had received vague instructions and lacked proper supervision. The mounting process dragged on for over twenty years and became exceedingly expensive. This paper seeks to understand why the instrument failed and how it eventually was transformed into an exhibition piece.
