Hans Petter Langtangen

Professor Hans Petter Langtangen, passed away on October 10th, 2016.  Hans Petter was an extraordinarily productive author, lecturer, supervisor and researcher. His books on software and methods for solving differential equations are widely used and have influenced these fields considerably. He established one of the most popular enduring courses at the University of Oslo and supervised nearly 100 MSc or PhD graduates.  Scientifically, he was always concerned with the efficient solution of differential equations, in terms of both CPU and human efforts. He produced scientific software of extremely high quality that has found users all over the world. Hans Petter was also leader of the Center for Biomedical Computing; a Norwegian Center of Excellence. The scientific computing community also knows him as a long time member of the editorial board of SISC, and, in particular, as the Editor-in-Chief from 2011 to 2015.

Hans Petter is sorely missed, and the CSEConf2017 conference is organized as a tribute to his achievements and impact on the scientific computing community. Several members of the community have shared their stories and memories of Hans Petter on this memorial web site.
