This knowledge drives the development of new therapeutic strategies and drugs.

## Why They Matter
H. Robert Horvitz matters because he transformed the scientific understanding of cell death from a passive event into an active, genetically controlled process. Before his work, the mechanism by which cells died during development was largely unknown; he proved that specific genes dictate this process, a discovery that is now central to modern biology and medicine. His findings have influenced a generation of researchers and have direct implications for treating major human diseases, including cancer and Alzheimer's. Without his contributions, the field of developmental biology would lack a critical pillar of knowledge regarding how multicellular organisms are built and maintained.
