The published 2005 obituary that got the birth date wrong by three weeks. Posted on tothewomen.org, the Society for Invertebrate Pathology’s memorial site for women of the field. The obituary recorded Sophie’s birth as January 21, 1922 — three weeks off from the February 12, 1922 date Sophie had given in her own 1960 hand-written autobiographical statement.
Useful as post-mortem narrative for her late-career scientific work and the network of colleagues who memorialized her, but to be cited with caution: prefer Sophie’s own statement for the birth date, and cross-check any names that appear.
