This is not a talk on the work of Hans-Joachim Baues. According to MathSciNet Baues has 110 publications, among them 9 books. I feel I cannot do justice to his complete work. Instead this will be a talk in which I discuss some of his work which had overlaps with my research interests and report about our mathematical interaction.
