Guest Editorial

This issue contains five papers on algebraic and logical methods for data and modelling which were solicited for The Computer Journal in honour of the 60th birthday of John V Tucker. The topic reflects the focus of Tucker’s scientific career, and the computer journal—being the flagship journal of the BCS— represents a most appropriate forum to recognize this milestone. Tucker has throughout his life been committed to progressing British computing (science, technology, history and education) as well as the BCS. Tucker was born and raised in Wales, and studied mathematics at Warwick (BA 1973), and mathematical logic and the foundations of computing at Bristol (MSc 1974 and PhD 1977). He then spent a short period in research posts in Oslo and at the CWI in Amsterdam before returning to Britain for good: first to a research post at Bristol, then in 1981 to a lectureship at Leeds. He was promoted to Reader in 1985 and moved back to Wales in 1989 to the post of Professor of Computer Science at Swansea University where he remains today.
