Later, this hypothesis put forward by Hertz was cleared by another German physicist Philipp Eduard Anton von Lenard.

The famous experiment by Hallwachs that eventually lead to Einstein's photon hypothesis was conducted using a negatively charged zinc plate. I always thought that the effect was initially observed with a zinc plate because of its low work function, but just now I found out that there are many other metals with lower work functions.
