Pierre Trémaux (20 July 1818 – 12 March 1895) was a French architect, orientalist and photographer, and author of numerous scientific and ethnographic publications. His 1865 work Origine et transformations de l'homme et des autres êtres was a predecessor and precursor to the theory of punctuated equilibrium (Wilkins and Nelson, 2008).
