Spring-Summer History Newsletter now available
The digital version of AIP’s semiannual History Newsletter is now available on our website. This issue’s feature article by Rebecca Charbonneau looks at the development of astrophysics from the mid-19th century to the present, covering tightly intertwined developments such as research on stellar composition and life cycles, explorations of the implications of relativity, the emergence of radio astronomy, and the advent of multimessenger astronomy. Other articles introduce AIP’s new postdoctoral history fellow and Helleman grant recipients, spotlight our new history guides, check in with our grant-in-aid recipients, and revisit the public release of AIP’s Robert Oppenheimer oral histories.
For Pride Month, extracts from this interview with Povey explore how her research, political activism, and mid-career gender transition are intertwined.

A large addition to the Ronald E. Mickens Collection is now available on our repository. The new batch of over 100 photos includes photos from Mickens’ hometown of Petersburg, Virginia; photos of students, colleagues, and family members; and photos from the opening reception for the exhibit, “The African American Presence in Physics.” The collection has also been rearranged into series (1. Family and Personal Life, and 2. Career) to aid in research and browsing.
