Salome Gluecksohn-Waelsch pioneered developmental genetics, combining genetics and embryology to explore how genetic mechanisms influence embryonic development. Her innovative work demonstrated how single-gene mutations could affect mammalian morphogenesis, gametogenesis, and overall development, solidifying the mouse as a key model organism in genetics (Silver 2000). By using natural mutations as experiments, she linked genetic deletions to specific enzyme deficiencies and phenotypic traits, advancing our understanding of gene regulation, pleiotropy, and gene-environment interactions (Papaioannou 2019). At the Albert Einstein College of Medicine (Gilbert 2015), she chaired the Department of Genetics, integrating genetics into medical education and mentoring numerous scientists. She also championed gender equality in academia, inspiring many women to pursue careers in science (Papaioannou 2019).
