Ernst Ruska....the great inventor

The person that i'm going to write about is Ernst Ruska,the inventor of electron microscope.He is a German physicist,electrical engineer, and Nobel Prize winner for the design of the first electron microscope.
Electron Microscope is a microscope that uses electrons instead of visible light to produce highly magnified images of objects.This enable the scientists to use electron microscopes in many different fields of research like medicine,Chemistry,Biology and Physics.Electron microscopes enable us to see very small particles and atoms.Its resolving power and magnification power are factors that contributed to the high tech electron microscope.
Born in Heidelberg, Ernst August Friedrich Ruska earned an engineering degree from the University of Berlin in 1931 and a Ph.D. degree in 1933.In 1937 Ruska accepted a research position at Siemens-Reiniger-Werke. He remained there until 1955, when he became director of the Institute for Electron Microscopy of the Fritz Haber Institute. Concurrently, Ruska served at the institute and as professor at the Technical University of Berlin, from 1957 until his retirement in 1972.
I feel that he has contributed greatly to the society we are all living in today.Without him,there would not be electron microscope.Electron microscopes allow us to have a better understanding on the nano cells and how our organelles work.This allow the scientists and doctors to implement new medicine and cure for different diseases.Many different new medicines have been invented and diseases that were once consider deadly have been cured by these new medicines.
Hence,i feel that Ernst Ruska is a great physicist who have contributed greatly to the society.
