Pasadena, CA— Carnegie’s Allan Sandage, who died in 2012, was a tremendously influential figure in the field of astronomy. His final paper, published posthumously, focuses on unraveling a surprising historical mystery related to one of his own seminal discoveries.
While preparing a centennial history of the Carnegie Observatories in the early 2000s, Sandage came across an unpublished 1944 exchange between two prominent astronomers that piqued his interest. The conversation seemed to predate by a decade Sandage’s own work on stellar evolution in the mid-1950s.
Naturally, he wanted to investigate further.
