Gerhard Findenegg (1938–2019)

On 12 December 2019, our colleague and friend Professor Dr. Gerhard H. Findenegg (cf. Figure 1) passed away after just having completed the eighty-first year of his life. He leaves behind his wife Irmgard Findenegg-Gröll with whom he was married for fifty-four years, their three daughters Klara, Helene, and Eva with their spouses, and seven grandchildren. The Findenegg family lost a loving and caring husband, father, father-in-law, and grandfather who cannot be replaced. At the moment of writing this foreword our thoughts are once again with Gerhard's family.
