Doctor Henry Coleman was the primary physician on Nantucket Island. He treated the native captured by the reconnaissance mission to what should have been Boston, and was the first to spot the devastating effect the Nantucketter's viruses might have on Bronze Age populations.

His cottage hospital became the new center of medical learning, and he finished off the training of Dr. Justin Clemens, who went on to set up a School of Medicine in Kar-Duniash.
