In my opinion, the most treasured moment in the history of Leiden University is when it was founded in 1575. It’s a symbol of education, progress and intellectual curiosity that has continued to shape the world for over 400 years. There are certainly many significant moments in the history of Leiden University. One that comes to mind is the discovery of the speed of light* by alumnus Christiaan Huygens in the 17th century. It revolutionised our understanding of the universe and paved the way for modern physics.
*Note from editors: We asked ChatGPT what is the most beautiful or important thing about the university. Besides the founding, ChatGPT suggested Huygens with the above piece. The discovery of light speed is not correct. However, Huygens was the first to describe light as a wave.
