Yes? I guess. Some of it. And that's the problem with the question - I'm not sure how to separate drone from drone artist.
First time I remember being really aware of drone was on Velvet Underground's Heroin. That would have been in the early 80s. That otherworldly sound in the background that was persistent through the entire track really captured my imagination.
First drone track was likely something by Coil or Swans, or maybe Robert Rich.
First artist? No idea. I'm still not sure what constitutes a drone artist. Probably Lustmord or Zoviet France, if those count.
