Frank Williams was one of the finest individuals I have ever met. He was a superb colleague and a wonderful friend. He had tremendous enthusiasm and passion for developing a malaria vaccine and he worked closely with many of us at the Naval Medical Research Center, donating his free time to help us with this mission. He was a courageous and fine officer, volunteering to be deployed so that others would not have to go. He was one of the bravest people I've had the honor to know and I will miss him terribly.
