It is with our greatest sorrow to announce that our colleague and friend, Laszlo Prikler, unexpectedly passed away on the 30th March 2021, at the age of 59.

He was a very kind and supportive colleague and a scholar whose contributions profoundly impacted the professional progress of many in the power system transients community, i.a. as co-author of the ATPDraw manual or as instructor in several courses on modeling transient phenomena using EMTP-ATP. He had a passion for details and perfection, and never missed a chance to give his full attention to students, colleagues or industry partners asking him for advice or contribution.

He received the IEEE PES Region 8 Outstanding Engineer Award, he was member of the Leuven EMTP Center Steering Committee, and served as Deputy Chairman and Chairman of the European EMTP-ATP Users Group association. He was an honorary member of IPST (International Conference on Power Systems Transients) Steering Committee.

He will be sorrowfully missed.
