The relationship between dinosaurs and birds has been observed for at least 150 years, although until the 1990s the idea was that birds were descendants of dinosaurs, not the other way around.

Still, the idea that at least some dinosaurs might have had feathers predates Jurassic Park by decades. I distinctly remember learning about this possibility in my first grade classroom, which would have been 1988 at they latest.

You are correct. The idea of dinosaurs with feathers is older than the 90s, even Dr. Alan Grant suggests this when speaking about raptors, on the other hand evidence appeared until mid 90s.
