<h2>Answer: Marie Curie

Explanation:
The Enlightenment was a period of great change in Europe and the United States in scientific practices and thinking that began in the late 17th century in the wake of the scientific revolution in the late Middle Ages.

The Enlightenment was therefore a period of great human knowledge. This knowledge came about because man increasingly used scientific methods based on reason and realism rather than belief in supernatural forces or other babblings. The Christian Church was increasingly criticized after the new sciences and practices gave rise to a secular worldview.
