One doctor developed the world's first vaccine. One civil rights activist helped to end racial segregation in the USA. One watchmaker saved the lives of 800 Jews and refugees during World War Two. One linguist opened a centre for young widows and saw revival spread across India. One former slave escorted 300 others to freedom. One pastor saw a revival in his church which sparked the birth of Pentecostalism. Faith. Love. Generosity. Sacrifice. Perseverance.
