Who first postulated quantisation of charge

[Jippo]

Friends,

I am trying to ascertain who first postulated that the electron had a charge that was quantised.

I know all about Millikan's experiment. It's fairly clear he knew what he was looking for but I want to know basically who told Millikan.

It's for a simple backround piece for a Laborotory Report

Cheers if ye can help.

Apologies,

It appears that sustained work by Thompson et al, suggested that charge may be quantised but that Millikan had demonstrated it indeed.

Cheers.
