Summary:
- The man who measured properties of the electron was Robert Millikan (1868-1953) He taught himself physics while a student at Oberlin College since there was nobody on the faculty to instruct him in this field.
- Millikan carried out a series of experiments between 1908 and 1917 that allowed him to determine the charge of a single electron.
- He determined the charge to be 1.5924 × 10-19 C, where C stands for coulomb, which is one ampere/second.
- The accepted value today is 9.10938215 ×10-31 kg.
