Marcus Whitman was one of the first white settlers in Oregon and a missionary. Together with his wife, they tried to convert the local Indian tribes to Christianity. Yet, their efforts ended up in a measles outbreak to which the Indians weren't immune. Since measles was a common disease in Europeans, the Indians suffered much harder. As a result, they believed Marcus Whitman and his wife poisoned the tribe and killed them. This story is about the good effects of Marcus Whitman's life in Oregon, his role in the first settlements, and other deeds. In addition, an author presents Whitman as a Christian martyr and a great man of faith.
