John William Draper

One of Draper's books, the ''History of the Conflict between Religion and Science'', popularised the conflict thesis proposing intrinsic hostility in the relationship between religion and science. It was widely read and was translated into several languages.
His son, Henry Draper, and his granddaughter, Antonia Maury, were astronomers. His granddaughter, Carlotta Maury (Antonia's younger sister), was a paleontologist. His eldest son, John Christopher Draper, was a chemist; and son Daniel Draper, a meteorologist. Provided by Wikipedia
