Europe saw a huge upheaval during the Reformation, starting with Martin Luther in Germany in 1517. This movement sought to reinstate the authority of the Bible for belief and practice, which had been lost over the centuries. Out of this thinking there arose many scientists with a strong Christian faith who began to critically re-evaluate the way science and medicine were being done in Europe. This biblical movement overturned the pagan philosophies of Aristotle, Ptolemy and Galen that ruled science at the time and set in place a method based on empirical investigation; it was this method that paved the way for modern science.

It would be too lengthy a task to compile the hundreds of key people of science and medicine that came from this biblical movement, so I have selected only a small number. Underneath each person is a quotation about faith. In some cases I have chosen biographical quotes and I have also put the people in chronological order.
