The Radiocarbon community has sadly lost a number of highly esteemed colleagues in recent years. To commemorate the contributions of these researchers, we set out to prepare a memorial issue. We met virtually several times with our associate editors during 2020–2021 to discuss the content and scope of this collection. During these discussions, the project grew to include retrospective articles about the early years of radiocarbon dating, as well as contributions about radiocarbon’s ever-widening range of applications and their most recent developments.
We are proud to present part 1 of the collection in this issue of Radiocarbon (part 2 will be published in the next issue) as we enter our sixty-fourth year of continuous publication. We honor and appreciate our radiocarbon colleagues, past and present, and thank the authors for their submissions. We are especially grateful for the close collaboration of our associate editors during the preparation of these special issues.
We acknowledge with regret that given the seventy-plus years of radiocarbon history, it would not be possible for us to compile all the memorials and histories in one or even two issues. Therefore, we encourage the submission of additional historical/memorial contributions.

At the end of this brief introductory section, we have included a recommended reading list of historical articles. The list is not comprehensive but could serve as a good starting place for readers looking for some background on the radiocarbon method and its evolution.
