Here's my preliminary "help" list, including several suggestions from people on another web site where I asked the first (but not second) question:
A. People who were inspired by Jesus to change the world for the better in a serious way:
(Saint) Alcuin; (King) Alfred; (Saint) Ambrose; Benigno Aquino; (Saint) Augustine; Bach; (Saint) Benedict; Francis Bacon; Roger Bacon; Bartelome (Des Las Casas); William and Catherine Booth; Rudy Bridges; Robert Boyle; John Bunyan; Jean Buridan; John Calvin; William Carey; Clement (of Alexandria); Charles Colson (second career); Copernicus; Dante; Fyodor Dostoevsky; Jean-Henri Dunant (Red Cross); Michael Faraday; Francis (of Assisi); Millard Fuller (Habitat for Humanity); Mohandas Gandhi; Wilhelm Grimm; Robert Grosseteste; Hans Hague; George Handel; Paul Hewson (Bono); Justin (Martyr); Johannes Kepler; John Paul II; Martin Luther King; Benjamin Lay; C. S. Lewis; David Livingstone; Martin Luther; Lin Yutang; John Milton; George Muller; Nelson Mandela; Isaac Newton; Blaise Pascal; (Saint) Patrick; William Penn; Jackie Pullinger; Mateo Ricci; Pandita Rumabai; Ram Mohan Roy; Mary Slessor; Alexander Solzhenitsyn; Sun Yat-sen; Hudson Taylor; (Mother) Theresa; J. R. R. Tolkien; Leo Tolstoy; Cameron Townsend; Alessandro Volta; Lech Walensa; William Wilberforce; Richard Wurmbrand; John Wycliffe; Xi Shengmo.
B. People who were inspired by Jesus to mess up the world in a serious way:
I just thought of this question, and am now taking suggestions for both. Bare in mind that the criteria are (1) people inspired by Jesus in important and relevant ways, whether or not they were Christians (2) who changed the world in important ways (3) deriving from that inspiration.
