Etelka Farkas is Emeritus Professor (2016) at the Faculty of Science and Technology, Department of Inorganic and Analytical Chemistry at the University of Debrecen, Hungary. After receiving her scientific degree (D.Sc.) from the Hungarian Academy of Sciences (HAS) in 1998, she has worked as elected member in some HAS Committees, e.g., the Committee on Physical Chemistry and Inorganic Chemistry (2011–) and the Doctoral Council of Chemical Sciences (2018–2021), and she chaired the Working Commitee of Coordination Chemistry (2011–2017). From 2006 to 2019, she was also Chair of the International Relations of the Hungarian Chemical Society. Her research has been focused, first of all, on the bio-induced solution study of metal complexes with a large variety of ligands, e.g. amino acid-, peptide-, and hydroxamic acid-based ligands, and the results have been presented in ca. 180 publications. Professor Farkas was Editor of the RSC Specialist Periodical Reports (Vols. 37, 38, and 39) on Amino Acids, Peptides, and Proteins for the years 2012, 2013, and 2015. Furthermore, she was Guest Editor of the Special Issue 472 (2018) of Inorganica Chimica Acta and of the issue 206 (2020) of the Journal of Inorganic Biochemistry. She received many awards; to mention just three of them: (2005) Gold Cross of Merit of the Hungarian Republic; (2012) Albert Szent-Györgyi Award; and (2022) Academy Prize, Awarded by the HAS. Celine J. Marmion is Professor of Bioinorganic Chemistry (since 2018) and Deputy Dean for Student Engagement (2018–2024) in RCSI, University of Medicine and Health Sciences, Dublin, Ireland. Her current research focusses on the rational design and development of innovative, multi-targeted metallo-drug candidates as anticancer or antimicrobial drugs. She has a track record in commercializing her research with the patient at the heart of all that she does. In this regard, she, together with colleagues, executed a pharma license agreement on a metallo-drug technology in 2010 and, more recently, entered into an industry-funded collaboration and option agreement with another pharma in 2016. Professor Marmion has undertaken many senior leadership roles within and outside her university. She is currently an active Council member of the Society of Biological Inorganic Chemistry. She was President of the Institute of Chemistry of Ireland, the national body representing all chemists in Ireland from 2019 to 2022, the third female only to be elected as President since its establishment in 1922. She also co-founded the Irish Biological Inorganic Chemistry Society in 2017 and served as its President from 2018 to 2020. Professor Marmion is a strong and vocal advocate for young scientists. In this regard, she played a key role in the establishment of the Institute of Chemistry of Ireland Young Chemists’ Network. She is also deeply committed to nurturing excellence in the education of students. She was the recipient of national "Teaching Hero" awards in 2021 and 2016 (as nominated by students) and numerous RCSI President's Teaching Awards. Astrid Sigel has studied languages; she was an Editor of the Metal Ions in Biological Systems (MIBS) series (until Volume 44) and also of the Handbook on Toxicity of Inorganic Compounds (1988), the Handbook on Metals in Clinical and Analytical Chemistry (1994; both with H. G. Seiler and H.S.), and on the Handbook on Metalloproteins (2001; with Ivano Bertini and H.S.). She is also an Editor of the MILS series from Volume 1 on, and she co-authored more than 50 papers on topics in Bioinorganic Chemistry. Helmut Sigel is Emeritus Professor (2003) of Inorganic Chemistry at the University of Basel, Switzerland. He is a Co-editor of the series Metal Ions in Biological Systems (1973–2005; 44 volumes) as well as of the Sigels' new series Metal Ions in Life Sciences (since 2006). He also co-edited three handbooks and published over 350 articles on metal ion complexes of nucleotides, amino acids, coenzymes, and other bio-ligands. Together with Ivano Bertini, Harry B. Gray, and Bo G. Malmström, he founded (1983) the International Conferences on Biological Inorganic Chemistry (ICBICs). He lectured worldwide and was named Protagonist in Chemistry (2002) by Inorganica Chimica Acta (issue 339). Among Endowed Lectureships, appointments as Visiting Professor (e.g., Austria, China, Japan, Kuwait, UK), and further honors, he received the P. Ray Award (Indian Chemical Society, of which he is also a Honorary Fellow), the Alfred Werner Award (Swiss Chemical Society), and a Doctor of Science honoris causa degree (Kalyani University, India). He is also an Honorary Member of SBIC (Society of Biological Inorganic Chemistry). Eva Freisinger is Associate Professorof Bioinorganic Chemistry and Chemical Biology (2018) at the Department of Chemistry at the University of Zürich, Switzerland. She obtained her doctoral degree (2000) from the University of Dortmund, Germany, working with Bernhard Lippert, and spent three years as
