A method of recording images or information using electrons, such as in photocopying machines or electron microscopy.
Combination of 'electron' (Greek elektron) and '-graphy' (from Greek graphein, to write). This noun emerged in the 1930s-1950s as photocopying technology was being developed and refined.
Before Xerox perfected electronography in the 1950s, people had to manually copy important documents by hand or use messy carbon paper—the electron-based process was genuinely revolutionary for offices and schools.
