The Louisa Gross Horwitz Prize

Columbia University has awarded the Louisa Gross Horwitz Prize for outstanding basic research in biology or biochemistry since 1967. The prize honors a scientific investigator, or group of investigators, whose contributions to knowledge in biology or biochemistry are deemed worthy of special recognition. The prize is awarded by a panel of internationally known scientists distinguished in the fields of biology, chemistry, biochemistry, and physiology.

Prize Qualifications

The Prize Committee recognizes no geographical limitations. The prize may be awarded to an individual or group. When the prize is awarded to a group, the honorarium will be divided among the recipients, and each member will receive a citation. Preference will be given to work done in the recent past.


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.

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.

Prize recipients discuss their research as part of a lecture series at Columbia. For more information, view the Horwitz Prize Lecture Series.
