German physicist who co-developed a scanning and tunneling microscope, which earned him the 1986 Nobel Prize in Physics. He was appointed an IBM Fellow in 1987. At only 10 years old, without knowing very much about the technology, he made a decision to turn into a physicist. The checking and tunneling microscope he developed allowed scientists to review specific atoms, a breakthrough because of its time. He wedded Lore Wagler in 1969. Ernst Ruska, his partner in developing the electron microscope, distributed his Nobel Reward award.
