Catholic Scientists


List of Roman Catholic cleric–scientists

Many Roman Catholicclerics[1] throughout history have made significant contributions to science. These cleric-scientists include such illustrious names as Nicolaus Copernicus, Gregor Mendel, Georges Lemaître, Albertus Magnus, Roger Bacon, Pierre Gassendi, Roger Joseph Boscovich, Marin Mersenne, Francesco Maria Grimaldi, Nicole Oresme, Jean Buridan, Robert Grosseteste, Christopher Clavius, Nicolas Steno, Athanasius Kircher, Giovanni Battista Riccioli, William of Ockham, and others listed below. The Catholic Church has also produced many lay scientists and mathematicians.

The Jesuits in particular have made numerous significant contributions to the development of science. For example, the Jesuits have dedicated significant study to earthquakes, and seismology has been described as "the Jesuit science."[2][3] The Jesuits have been described as "the single most important contributor to experimental physics in the seventeenth century."[4] According to Jonathan Wright in his book God's Soldiers, by the eighteenth century the Jesuits had "contributed to the development of pendulum clocks, pantographs, barometers, reflecting telescopes and microscopes, to scientific fields as various as magnetism, optics and electricity. They observed, in some cases before anyone else, the colored bands on Jupiter’s surface, the Andromeda nebula and Saturn’s rings. They theorized about the circulation of the blood (independently of Harvey), the theoretical possibility of flight, the way the moon effected the tides, and the wave-like nature of light."[5]
