Floris Takens (1941-2010), Professor of Mathematics at Groningen University, became an editor of the Lecture Notes in Mathematics in 1989. Floris Takens made outstanding contributions to dynamical systems. He coined, together with David Ruelle, the now famous term "strange attractor". His mathematical culture was vast and his contribution to the development of the LNM over two decades was pivotal. We, the Springer mathematics editorial staff and the editors of the LNM, mourn his passing and bear him in fond and grateful remembrance.
