Peter Armbruster\, an outstand ing personality\, was a gifted explorer with exceptional multiple talents\ , skills and interests. He was an internationally renowned atomic and nucl ear physicist. Born 25 July 1931 in Dachau\, Peter Armbruster experienced formative years in his youth before studying physics at the TH Stuttgart a nd TH Munich\, where he obtained his doctorate (1961) and habilitation (19 64) under Professor Heinz Maier-Leibnitz. To pursue his research at the Mu nich Research Reactor (FRM)\, Peter Armbruster has built an innovative gas -filled separator\; the beginning of a lifelong liking of these instrument s and a basis of his scientific career. Skipping interesting years of Pete r Armbruster as a scientist and science advisor at a variety of research i nstitutes\, this contribution will focus on i) his role as one of the foun ding directors of GSI (beginning 1971) – briefly mentioning selected asp ects of the early period of GSI\, its founding and building the UNILAC acc elerator and SHIP recoil separator – and ii) his pioneering contribution s from 1976 to 1989\, as the division head leading the SHIP group step-by- step to the discovery of the superheavy elements 107\, 108\, and 109\; lat er named bohrium\, Bh\, hassium\, Hs\, and meitnerium\, Mt\, respectively. Again\, the three-year intermission period\, which began in 1989\, when h e was seconded to the European Institute Laue-Langevin (ILL)\, Grenoble\, as the Research Director\, will be skipped. Back at GSI in 1992\, he enjoy ed the discovery of elements 110\, 111\, and 112 (1994-96) at the\, in the meantime\, upgraded SHIP and the naming of these elements darmstadtium\, Ds\, roentgenium\, Rg\, and copernicium\, Cn\, respectively. With this eno rmous success\, which significantly contributed not only to our understand ing of one of the limits of nature and but also to the scientific reputati on of GSI\, Peter Armbruster retired on June 30\, 1996. However\, in the s ubsequent years\, he remained highly interested in all aspects of superhea vy element research. As a real friend of the nuclear chemistry at the GSI\ , he closely observed the superheavy element research at the gas-filled se parator TASCA. For more than two decades after his retirement\, he attende d international conferences and remained a critical and inspiring discussi on partner. Peter Armbruster\, a wonderful person\, passionate scientist\, dear colleague\, good advisor\, and a nature and peace loving true Europe an passed away on June 26\, 2024.\n\n\n\n\n\nBeatriz Jurado (LP2iB\, CNRS/ IN2P3\, France)\n\n \n\n\nFond Memories Presented by Monique Bernas\nClos ing Remarks \n\nFrom ca 6:30pm: reception at the GSI Canteen. \nRegistra tion is required\, both for in-person and online participation! \n \n\n  \nZoom Access: https://gsi-fair.zoom-x.de/j/68377952941Meeting-ID: 683 7795 2941 Kenncode: Coll-2306 \n\n \n\nhttps://indico.gsi.de/event/25197/ LOCATION:Main Lecture Hall & Zoom (GSI) URL:https://indico.gsi.de/event/25197/ END:VEVENT END:VCALENDAR
