On the Episcopal and Lutheran calendars, Jan Hus (c. 1372-1415) is honored today. He was the Czech priest who, along with the earlier John Wycliffe, is considered one of the first church reformers. Influenced by the legacy and writings of Wycliffe, Hus criticized aspects of Catholic doctrine over a century before Luther's efforts, such as aspects of eucharistic doctrine, the moral failings of the clergy, the Crusades the practice of indulgences, and other aspects. He was executed for heresy, but followers of his teachings, the Hussites, continued his efforts.
On the Roman Catholic side, a famous and beloved saint, Maria Goretti, is also honored today. Here is the page about her from the American Catholic site: http://www.americancatholic.org/Features/Saints/saint.aspx?id=1436&calendar=1
