Condolences to the Martin family. While I never knew John, his contribution to find a cure for HPV C had a huge impact on my life and my families. I carried the hep C virus genotype A, a notoriously difficult strain to cure. The first drug from a competing Co. did not clear it, it was one of the later drugs from Gilead that finally did. Mine is a success story and to the many who died from liver complications related to Hep C, their deaths ultimately gave me back my life, which in a large part was due to the efforts of John Martin. For that I shall always be grateful. Again, God's blessings to your family.
