Many of us were saddened to hear of Michael Waring's death in November 2019 and wanted to do something to convey our admiration for his life in science, and to express our personal gratitude for his friendship, mentorship, and general guidance over many years. Michael was one of the founders of the small‐molecule–DNA interaction field and this special issue in his honour is a small token of appreciation

About 30 years ago, before the term “chemical biology” was part of our lexicon, a small number of organic chemists recognized that they could apply their skills in synthesis, molecular design and physical characterization to the field of nucleic acid chemistry. Much of this was made easier by Marv Caruther's development of phosphoramidites, which meant that oligonucleotides of DNA and RNA could be

1 INTRODUCTION During a long and extremely productive scientific life Michael Waring made substantial contributions to the understanding of certain fundamental physical properties of the DNA double helix. In this review I summarize his early studies on DNA supercoiling and his later conclusions on the role of natural DNA base analogues in determining DNA stiffness and nucleosome positioning. The latter
