When was Coulomb's law discovered and who invented electric field lines?

[pmb_phy]

Does anyone know when Coulomb discovered his law? And does anyone know when the concept of electric field lines was invented? I know that Faraday created the idea for the magnetic field and I was wondering if it was he who applied it to the electric field or was it someone else?

Sources of information will be appreciated since I will eventually have to refer to the source of information.

Thank you

Pete

Well I found the Coulomb part. His experiment was published in

Charles A. de Coulomb, History Royal Acad. Sci. (France), 1785, pp. 569 and 579.

The rest I'm still searching for. Thanks.
