Other papers by Dr. Starzl were mentioned on social media to a smaller extent, but were often initiated by colleagues who were remembering his contributions. One example is his 1963 paper, "The reversal of rejection in human renal homografts with subsequent development of homograft tolerance" \cite{starzl1963reversal}, which was mentioned a few days after his death by a colleague on Twitter, who pointed out the significance of this particular paper.
