Willi Hennig Society

The Willi Hennig Society is a forum for advancing the science of phylogenetic systematics. Founded in 1980 and based in Washington, DC, the Society provides a platform for diverse workers in systematics to debate and share ideas, with an emphasis on empirical work and the principles of cladistics. The Society's journal, Cladistics, has been instrumental in documenting the benefits it has brought to the field of systematics.
