Helena Durnová (Masaryk University, Brno, CZ) holds a Ph.D. in history of mathematics from Masaryk University in Brno and apart from research in history of mathematics and computing, she teaches courses on history of mathematics, computing, and science. She is interested in the history of modern mathematics and in particular in the links between mathematics and other realms of intellectual activity, such as computing, technology, science, and education. She also works in history of computing and with Arianna Borelli, she co-edited the book Computing Cultures: Knowledges and Practices (1940–1990).Danny J. Beckers (Vrije Universiteit Amsterdam, NL) studied mathematics and cultural history. He did his PhD at Nijmegen university, on a topic in the history of mathematics education in the early 19th century Dutch kingdom. He is currently working as an assistant professor at Vrije Universiteit Amsterdam, where he lectures about the history of mathematics and history of computing at both the bachelor's and master's level. His research interests are in the history of mathematics and programming education, as well as the role of mathematics in culture. Snezana Lawrence is a historian of mathematics and mathematics educationalist, with a particular interest in the links between mathematics, architecture, philosophy and epistemology of mathematics. In terms of geography, her expertise is in the history of mathematics in Yugoslavia, Serbia, England, and France (18-20th centuries). Snezana was the Chair of History and Pedagogy of Mathematics International Study Group (affiliate of ICMI) for 2020-24 and is the Chair of the steering committee to establish a new IUHPST Commission on Education and Science. Petra Antošová (Masaryk University, Brno, CZ) is assistant professor at the Department of Mathematics at the Faculty of Education, Masaryk University, where she also lectures on algebra, set theory, and mathematical competitions. Recently, she finished her PhD studies on a topic in the history of set theory in Czech mathematical literature in the 19th and 20th centuries. She is a member of the Mathematical Olympiad problem committee for lower secondary schools in Czechia.
