  Roger Carter (1934--2022) was a very well known mathematician working in
algebra, representation theory and Lie theory. He spent most of his
mathematical career in Warwick. Roger was a great communicator of mathematics:
the clarity, precision and enthusiasm of his lectures delivered in his
beautiful handwriting were hallmark features recalled by numerous students and
colleagues. His books have been described as marvelous pieces of scholarship
and service to the general mathematical community. We both met Roger early in
our careers, and were encouraged and influenced by him~ -- ~and his lovely
sense of humour. This text is our tribute, both to his mathematical
achievements, and to his kindness and generosity towards his students, his
colleagues, his collaborators, and his family.
