Holbrook Kohrt with his mentor and colleague, Ron Levy

Holbrook Kohrt (1977-2016)

It is with real sadness that we must share the news that our colleague Holbrook Kohrt died on February 24, 2016.   Holbrook had been battling a serious illness all of his life, and in recent years had become resistant to standard Factor VIII therapy.  He had been on investigational therapy for his disease, but became extremely ill and was transferred to Miami, where he died.  Holbrook was, by everyone's estimation, one of the most brilliant translational researchers of his generation, and was poised to make great contributions to the conquest of cancer. His novel cancer immunotherapy preclinical work led directly to the development of clinical trials that may transform the care of cancer patients. His loss is a personal one for those of us who knew him, but also a real loss for cancer patients everywhere.  Let us join in remembering a physician-scientist who bravely faced a life-threatening disease, never gave in, and gave his all in the service of cancer research and cancer patients.  Read his story in the New York Times, March 1. 

Those wishing to make contributions in Holbrook's memory may direct gifts to:  Holbrook Kohrt Memorial Fellowship Fund, Medical Center Development, 3172 Porter Drive, Suite 210, Palo Alto, CA 94304
