I'd suspect most people are aware of him as some tangential element to a band or bands that are far better known:

Bowie, Talking Heads, Devo, U2 ... almost all of it getting some subtle Eno flavor. He never struck me as overbearing or obvious on his work, generally just adding a little bit of him on top of whoever he was producing/working with.

Here I'll admit that I think Another Green World starts really strong and falls off. It's a beloved album but I'll happily take my downvotes in preferring HCTWJ.

I bought HCTWJ first but Another Green World is the one I really wore out the grooves on. And I think the ambient stuff after that is so-so.
