The Louisa Gross Horwitz Prize


Columbia University Irving Medical Centre


The Louisa Gross Horwitz Prize was established under the will of the late S. Gross Horwitz through a bequest to Columbia University and is named to honor the donor's mother. Louisa Gross Horwitz was the daughter of Dr. Samuel David Gross (1805–1889), a prominent Philadelphia surgeon and author of the outstanding Systems of Surgery, who served as President of the American Medical Association.

Each year since its inception in 1967, the Louisa Gross Horwitz Prize has been awarded by Columbia University for outstanding basic research in the fields of biology or biochemistry. The purpose of this award is to honor a scientific investigator or group of investigators whose contributions to knowledge in either of these fields are deemed worthy of special recognition.

The prize consists of an honorarium and citation that are awarded at a special presentation event. Unless otherwise recommended by the Prize Committee, the prize is awarded annually.


The purpose of this prize is to reward scientists that have made recently transformative discoveries not yet recognized by high visibility international awards. The Prize Committee recognizes no geographical limitations. The Prize may be awarded to an individual or a group. When the Prize is awarded to a group, the honorarium will be divided among the recipients, but each member will receive a citation.

Re-nomination(s) are by invitation only. Self-nominations are not permitted.
