The Heidelberg Laureate Forum Foundation presents the HLF Laureate Portraits: Robert Melancton Metcalfe, ACM A.M. Turing Award, 2022. Interview recorded in 2023. In this series, join us as we meet with the top mathematicians and computer scientists – recipients of the Abel Prize, the ACM A.M. Turing Award, the ACM Prize in Computing, the Fields Medal, the IMU Abacus Medal and the Nevanlinna Prize. We ask them about their lives, their research, their careers and the circumstances that led to their awards.

Background: The Heidelberg Laureate Forum Foundation (HLFF) annually organizes the Heidelberg Laureate Forum (HLF), which is a networking conference for mathematicians and computer scientists from all over the world. The HLFF was established and is funded by the German foundation Klaus Tschira Stiftung (KTS), which promotes natural sciences, mathematics and computer science. The HLF is strongly supported by the award-granting institutions, the Association for Computing Machinery (ACM: ACM A.M. Turing Award, ACM Prize in Computing), the International Mathematical Union (IMU: Fields Medal, IMU Abacus Medal, Nevanlinna Prize), and the Norwegian Academy of Science and Letters (DNVA: Abel Prize). The Scientific Partners of the HLFF are the Heidelberg Institute for Theoretical Studies (HITS) and Heidelberg University.
