Louisa Gross Horwitz Prize ceremony at Columbia University honoring Moser, Moser, and O’Keefe for foundational work on spatial representation.
On 31 October 2013, May-Britt Moser, Edvard I. Moser, and John O’Keefe were formally awarded the 47th Louisa Gross Horwitz Prize for Biology or Biochemistry at Columbia University. The prize recognized their collective work on the neural basis of spatial representation, linking hippocampal place cells with entorhinal grid cells into a coherent positioning system in the brain.
The Horwitz Prize is one of the most prestigious awards in biomedical science and has often foreshadowed later Nobel recognition. Receiving it placed Moser among an elite group whose fundamental discoveries have reshaped modern biology and medicine. The award specifically honored how grid cells, discovered by the Mosers, complemented O’Keefe’s earlier identification of place cells, thereby revealing a multi-layered spatial coding system.
In the broader historical context, this ceremony signaled the maturing of cognitive and systems neuroscience as a field capable of explaining complex mental functions at the level of identifiable circuits and cell types. For women’s history, Moser’s presence on this distinguished stage emphasized the increasing, though still limited, visibility of women as senior leaders in experimental neuroscience. The Horwitz Prize contributed to international recognition of her role in transforming our understanding of how the brain constructs maps of the environment and supports navigation and memory.
