Known for its prestige, the Nobel Prize attracts attention beyond typical scientific awards, amplified by widespread media coverage and an extensive data archive of nominations. I have compiled a unique dataset of Nobel Prize nominations in the categories of Physics and Chemistry. This dataset allows for an in-depth analysis of the nomination network, guided by a theoretical triad that emphasizes the central role of nominators in power dynamics situated within sociological discourses on particularistic selection criteria, global shifts in scientific hegemony, and academic prestige stratification.Findings reveal indications of a gender disparity and organizational privilege in the selection of nominators. Nomination power is unevenly distributed, especially across countries, and reveals a macro-sociological shift in scientific leadership from Germany to the United States. However, there is insufficient evidence of a clear organizational hierarchy in the successful placement of nominations. This suggests that placement power is not limited to highly prestigious organizations. In fact, newcomer organizations have an advantage in successfully placing nominations, demonstrating that organizational renewal can disrupt existing hierarchies within selection processes. This study highlights the importance of analyzing the scientific prize landscape at different levels. It extends the knowledge of the Nobel nomination network, in particular by providing an organizational view of top performers and scientific centers.
