[Ashcroft & Mermin 10] The model was extended in 1905 by Hendrik Antoon Lorentz (and hence is also known as the Drude–Lorentz model) [7] to give the relation between the thermal conductivity and the electric conductivity of metals (see Lorenz number), and is a classical model.
The model is named after the Dutch physicist Hendrik Antoon Lorentz. It is a classical, phenomenological model for materials with characteristic resonance frequencies (or other characteristic energy scales) for optical absorption, e.g. ionic and molecular vibrations, interband transitions (semiconductors), phonons, and collective excitations ...

1894 – Paul Drude introduces the symbol c for speed of light in vacuum. 1895 – Hendrik Lorentz corrects his 1892 model, proposing a contraction by the Lorentz factor (γ). 1895 – Albert Einstein probably makes his thought experiment about chasing a light beam, later relevant to his work on special relativity.
Paul Drude (c. 1900) realized that the phenomenological description of conductivity can be formulated quite generally (electron-, ion-, heat- etc. conductivity). Although the phenomenological description is incorrect for conduction electrons, it can serve as a preliminary treatment.
Although the Drude model was fairly successful in describing the electron motion within metals, it has some erroneous aspects: it predicts the Hall coefficient with the wrong sign compared to experimental measurements, the assumed additional electronic heat capacity to the lattice heat capacity, namely per electron at elevated temperatures, is also inconsistent with experimental values, since ...
As far as I know, The Drude-Lorentz model is called that because it is based on the Lorentz dipole oscillator model for electrons first published by Lorentz in 1878, with ω 0 = 0 due to the lack of interaction between the nuclei and conduction electrons.
