Christopher Clavius

Christopher Clavius. Christopher Clavius (25 March 1538 – 6 February 1612) was a Jesuit German mathematician and astronomer who modified the proposal of the modern Gregorian calendar after the death of its primary author, Aloysius Lilius. Clavius would later write defences and an explanation of the reformed calendar, including an emphatic acknowledgement of Lilio's work. In his last years he was probably the most respected astronomer in Europe and his textbooks were used for astronomical education for over fifty years in and even out of Europe. Provided by Wikipedia
