Issues 2-4 of volume 57 of the journal Complex Variables-Elliptic Equation (CV-EE) was dedicated to Unidel Professor Robert Pertsch Gilbert on the occasion of his 80th Jubilee. Friends, colleagues and ex-students contributed to this issue. The list of contributors are V. Maz’ya, D-C Chen, S. Carl, H. Begehr, Y. Xu, F. Wassouli, A. O. Celebi, R. Ronkese, F. Caconi, M. V. Klibanov, R. Kress, J-P. Groby, E. Ogam, A. Wirgin, G. N’Guerekata, X. Xie, M. Fang, P. Puci, M-Y. Ou, E. Wegert, S. Klinge, K. Hackl, B. Vernescu and P. Broadbridge among others. Currently the joint Editors-in Chief for CV-EE are Alexander Pankov and Yonzhi Xu. Robert Gilbert was the Editor for this journal until he resigned several years ago. He continues to co-edit Applicable Analysis. The special issue, including Professor Gilbert’s biography, can be found online at http://www.tandfonline.com/toc/gcov20/57/2-4.

The biography in this issue states that "It is amazing to realize how many mathematicians have been, and still are collaborating with Bob." It goes on to note that he has worked on many different subjects including "...elastic plate problems, linear and nonlinear elasticity,elastic-plastic problems, contact problems for thermo-elastic and elastoplastic shells, Hele Shaw flows, flows in porous media, under water acoustics, ...medical mathematics.” Also: "Bob's first monograph Function Theoretic Methods in Partial Differential Equations sold 10, 000 copies world wide, 7,500 in China alone." Professor Gilbert is a three-time winner of the prestigious Alexander von Humboldt Award.

The journal Mathematical Methods in the Applied Sciences will also dedicate an issue to Professor Gilbert and will appear later this year. That issue will contain papers by the authors Michael Klibanov, Alexander Pankov, Masahiro Yammamoto, Grigori Panasenko, Armand Wirgin, Rolando Magnani, Roger Temam, Umberto Mosco Roberto, Triggianni and Irena Lasiecka.
