In 1961, Donald L. Bitzer, co-inventor of the plasma display panel, and Chalmers W. Sherwin introduced Plato, the first computer based education system, the first time-shared education system, and the home of the first on-line community. By the early 1970s, Plato included early forms of electronic mail, newsgroups, and computer games and provided hardware and software innovations for the computer industry. By the late 1980s, Plato offered instruction on approximately 100 subjects to students around the world.
Sound on Film
Marker location: Southeast side of Everitt Laboratory
The first public demonstration of sound recorded simultaneously with pictures on film took place at the Urbana campus on June 9, 1922. Joseph T. Tykociner’s double-feature motion picture included ringing a bell and reading the Gettysburg Address. The invention was not patented. The first commercial talking film in 1927 used a phonograph, and Tykociner’s invention was only later recognized. It is still used for sound on film.
Theory of Superconductivity
Marker location: Bardeen Quad – Northeast of Engineering Hall
Theoretical physicist John Bardeen was the first person to win two Nobel Prizes in the same field. His first, in 1956, shared with Walter Brattain and William Shockley, was for the invention of the transistor, the basic component of electronic information technologies. His second, here at the University of Illinois in 1972, shared with postdoctoral associate Leon N. Cooper and graduate student J. Robert Schrieffer, was for the explanation of superconductivity, a state of matter first observed in 1911 in which materials lose all their electrical resistance at very low temperatures. The BCS theory, announced in 1957 and based on a model in which electrons form bound pairs, explains fundamental processes in solid-state physics, nuclear physics, astrophysics and particle physics.

James G. Randall raised the study of the Civil War and Reconstruction Era to a new level and changed the direction of Lincoln biography through research analysis of primary sources, and rigorous scholarly standards. His multi-volume Lincoln the President (1945) established Randall as the “dean” of Lincoln studies in his time.
Anthropology and Society
Marker location: West side of Davenport Hall
During the mid-twentieth century, two anthropologists made landmark contributions to their field. Julian H. Steward developed cultural ecology, a method for studying cultural change by analyzing the interaction of social life, environment, and technology. Oscar Lewis created innovative methods for community and family studies and published influential oral histories of the poor to document the human costs of poverty worldwide.
Illini Supersweet Corn
Marker location: West side of Davenport Hall
In 1953, John R. Laughnan discovered that kernels of a mutant corn were “unusually sweet.” Within eight years, Laughnan had developed the “Illini Supersweet” hybrid that revolutionized the sweet corn industry. Supersweet, now a dominant variety internationally, is higher in protein and lower in calories than conventional sweet corn.
Marker location: North side of Chemistry Annex
In the late 1940s, plant pathologist David Gottlieb isolated a strain of streptomyces, a soil bacterium. This bacterium produced an antibiotic compound that was developed into chloramphenicol, which helped save countless lives as one of the most important antibiotics of the “Golden Age of Antibiotics.”
Illinois Historical Collections
