When was the double slit experiment first performed with electrons?

[Safinaz]

Hi all,

I'd like to ask what was the first time the double- slit experiment have been made by electrons. In Brian Greene's film:


It's said to be in nineteenth twentieth, while at other webpages as:

http://en.wikipedia.org/wiki/Double-slit_experiment

it's said to be in 1961 or 1974. So what is true ?

The experiment Brian Greene refers to is electron diffraction which won the 1937 Nobel Prize for Physics.
The 1961 experiment is a double slit experiment with a beam of electrons, the 1974 experiment is a double slit experiment using a single electron.
