Notable awards

Michaelis received the 1975

IEEE Morris N. Liebmann Memorial Award The initially called Morris Liebmann Memorial Prize provided by the Institute of Radio Engineers (IRE), the IEEE Morris N. Liebmann Memorial Award was created in 1919 in honor of Colonel Morris N. Liebmann. It was initially given to awardees who h ...

"for the concept and development of single-walled magnetic domains (magnetic bubbles), and for recognition of their importance to memory technology." The single walled concept was the seminal idea that led to "magnetic bubbles" and charge coupled devices.
