A German-born mathematician, Muller was appointed Head Master of the Royal Military Academy in 1741. Later on the expansion of the college he became its Professor of Fortification and Artillery. He was widely considered to be both a leading technical authority and a superb educator, “the scholastic father of all the great engineers this country employed for forty years” [Hill Boswell I, p.351, quoted in DNB]. His publications were highly valued and rapidly translated into French and Spanish. The Attac [sic.] and Defence of Fortified Places… [1747] “… was widely quoted, and it alone would have assured Muller the reputation of an expert. Not content with this success, however, Muller not only brought out in 1760 an annotated translation of Clairac’s The Field Engineer, but in 1757 had published what has since come to be regarded as his most important work, the Treatise of Artillery. [Houlding Fit for Service… p.253].
