Catastrophe theory was introduced in the late 1960's by René Thom, but his book "Stabilité structurelle et morphogenèse" was only published in 1972. An english translation by David Fowler has been available since 1975. (Thom R. - Structural stability and morphogenesis. Benjamin Addison Wesley, New York, 1975.)

Thom's ideas were then developed by E.C. Zeeman who proposed many applications in various domains. (see Zeeman E. C. - Catastrophe theory, selected papers. Addison-Wesley publishing compagny, London, 1977.)
