The following was written with contributions by Jon Hetman, Lisa Pearson, and William (Ned) Friedman on behalf of the Arnold Arboretum community, and originally published on the arboretum's website.

In spring of 2022, Harvard University President Larry Bacow shared the findings of the Presidential Committee on Harvard and the Legacy of Slavery, a major initiative focused on researching and day-lighting connections between Harvard and its community to both the institution and economy of slavery. Among the Committee’s findings associated with the Arnold Arboretum is a major benefactor who made his fortune trading goods produced by enslaved people, the institution’s historical connections to the Atkins Institution in Cuba, and the close ties of some instructors at the Bussey Institution to the eugenics movement. At the Arnold Arboretum, we welcome this opportunity to better understand our past as important historical context in our efforts to make our landscape more welcoming and enriching to everyone.
