Superman, Whitney Ellsworth. Doc Cochran Dr. Amos "Doc" Cochran (Brad Dourif) is the only doctor in the camp of Deadwood. A veteran of the Civil War, he is an honest and moral professional who shows extreme dedication to and compassion for the sick and injured, without bias for their attitudes or loyalties. Doc Cochran is relatively invulnerable to the risk of violence in Deadwood, as he is valuable to Swearengen and Tolliver for his medical maintenance of the prostitutes, and as a result is unafraid to speak his mind to both of them, as well as many others, whenever their behavior is cold and cruel. He has been charged with grave robbery seven times. When the Reverend Smith is at his last extremity, dying of a brain tumor, Cochran prays for the reverend to be released from suffering, and weeps as he recalls the cries of agony he heard on the battlefield during the Civil War. When Swearengen falls ill in Season 2, Cochran refuses to lose another patient, despite being under so much stress he cannot stop his hands from shaking. In the end, he succeeds in treating Al and his confidence seems to improve again. He constantly displays a moral compass similar to humanist philosophy. When Chinese prostitutes appear in town, Cochran is shocked by the inhumane conditions in which they are kept. Much to his distress, he is barred from treating them and forced to simply stand by and watch them die. In Season 3, he becomes ill and shows symptoms of tuberculosis. Al, however, spurs him on not to just lie down and die, remarking "I ain't learning a new Doc's 'quirks'." As of Deadwood: The Movie, Cochran has survived and continues to treat a now ailing Al. Sol Star Solomon "Sol" Star (John Hawkes) is Seth Bullock's best friend and partner in the hardware business and the only Jewish resident of the camp. He is originally from Vienna, Austria. Imperturbable, reliable, and sensible, Sol becomes a rising force in the camp; originally seeing the potential wealth in providing tools to the prospectors in Deadwood, the second season sees Sol set his sights on forming the first bank in Deadwood in partnership with Alma Garret. Though mocked by Swearengen at every turn for his being Jewish, particularly during the initial phase of buying the future site of the Bullock and Star hardware store from the saloon
