Did people not already know that EM waves don't need a material medium?

I'm still wondering if the rocket shown was a Goddard design, and he
thought something with a single stage could go all the way to the Moon.
I'm trying to remember how much was known about radio waves at the time
- had anyone noticed radio interference from the Sun by that time? If
so, that settled the radio through space question right there.
