- Kepler is a short history of events leading to the astronomical discoveries of Johannes Kepler. It was written by Walter William Bryant, a staff member of the Royal Observatory, Greenwich. The book was published in 1920 by the Society for Promoting Christian Knowledge, London, and by The MacMillan Company, New York, within a series of books called “Pioneers of Progress.”

Soon after its publication Kepler’s “Epitome” was placed along with the book of Copernicus, on the list of books prohibited by the Congregation of the Index at Rome, and he feared that this might prevent the publication or sale of his books in Austria also, but was told that though Galileo’s violence was getting him into trouble, there would be no difficulty in obtaining permission for learned men to read any prohibited books, and that he (Kepler) need fear nothing so long as he remained quiet.
