- Kelvin's 1902 proposal Kelvin Lord Aepinus atomized Philosophical Magazine 1902 3 257 283 to use the term ‘electron’ in place of corpuscle is highly significant. It reflected the need to include the two historically different concepts of electron and ion in a single term. The first concept was unitary charge and the second meant more generally an atom of matter associated to a charge.

- In 1898, the problem of interpreting the photoelectric effect was still completely open. The phenomenology gathered was vast, and because there was no distinction made between low and high pressures, it appeared to be extremely complicated. After Lenard and Wolf's hypothesis Lenard P. Wolf M. Zerstauben der Korper durch das ultraviolette Licht Annalen der Physik und Chemie. 1889 2 443 456 that ‘metallic dust’ was responsible for the discharge was abandoned, the photoelectric effect was generically interpreted in terms of the molecules of the surrounding gas which, when they came into contact with the illuminated plates, became charged and acted as carriers for the electricity. See B. R. Wheaton, ‘Philipp Lenard and the photoelectric effect: 1889–1911’, Historical Studies in the Physical Sciences, 9 (1978), 299–322; S. Galdabini, G. Giuliani and N. Robotti, ‘Photoelectricity within classical Physics: from the photocurrents of E. Becquerel to the first measurement of the electron charge’, Proceedings of the European Physical Society (Como, 1992) (in press).

- In 1899, Lenard Lenard P. Erzeugung von Kathodenstrahlen durch ultraviolettes Licht Annalen der Physik 1900 2 359 375 provided an interpretation of the photoelectric effect in terms of corpuscles, which Lenard called ‘quantums’. He measured the charge-to-mass ratio, and obtained a value similar to that proposed by Thomson. Unlike Thomson, however, Lenard did not manage to measure the charge. This was possible for Thomson as he had already perfected (as we have seen) an ad hoc measurement technique precisely to measure charge. The e/m obtained by Lenard was reported by Thomson in Philosophical Magazine (footnote 32) as a confirmation of his own result.
