Friedrich Zernike

Friedrich Zernike was a Dutch physicist renowned for developing phase-contrast microscopy, a groundbreaking technique that allows scientists to view transparent, living cells without dyeing them. This innovation significantly advanced biological and medical research by providing detailed images of live specimens. Zernike's work earned him the Nobel Prize in Physics in 1953. His contributions helped improve microscopes' ability to examine delicate biological structures, making it easier to study processes like cell function and development in real time. Overall, his contributions have had a lasting impact on microscopy and life sciences.
