Albert Eagle was an English mathematician who wrote several books (some of them privately published) giving his forcefully expressed and somewhat eccentric views on science and mathematics. He was an assistant to J. J. Thomson, and was later a lecturer at Manchester University. His best-known book is (Eagle 1958) on elliptic functions, where he uses his idiosyncratic mathematical notation, such as τ instead of π/2 (ibid., p. ix), and !n for n factorial. In his other writings he dismissed special relativity, quantum mechanics, natural selection, and English spelling as absurdities (Bowler 2001, p.142).
