Clinton Joseph Davisson was a Nobel Prize winning American physicist, known for his discovery of electron diffraction. Born in late nineteenth century to a contract painter father, he had to support his own education from the very start. After graduating from Bloomington High School at the age of 21, he entered the University of Chicago in the same year. However, it took him around seven years to obtain his bachelor’s degree. For the greater part of his college years, he worked at the Princeton University as part time instructor, returning to the Chicago University only for the summer quarters. Rest of the time, he privately studied with eminent academics at Princeton, especially Professor O.W. Richardson. Late,r he did his doctoral work with Richardson and received his PhD in three years. Subsequently, he began his career as an Assistant Professor at Carnegie Institute of Technology; but very soon shifted to Western Electric Company, later renamed as Bell Telephone Laboratories. Here he spent his most productive years and performed the famous Davisson-Germer experiment, which resulted in the discovery of electron diffraction. Afterwards he joined University of Virginia as visiting professor of research, finally retiring from there after eight years.
