Introduction to pioneers in primatology.

As a relatively young discipline, primatology is lucky to still have many of its pioneering researchers active in the field. At the 2019 American Society of Primatology meeting, I convened the inaugural Pioneers in Primatology symposium to bring together a selection of these researchers to reflect on their careers, with a focus on the stories that defined their work and their thoughts on the important future directions for the field. After the symposium, Karen Strier and I decided that these pioneers' contributions merited preservation, and this special issue is our effort to do so.
