There's also a cameo by actor Dylan Baker in the sequel (maybe it was the first one, actually - it's been so long since I've seen the older ones) who portrays Dr. Connors. I think it was Raimi's plan to put that little Easter egg in there and then hope to deal with his own interpretation of Dr. Connors in later iterations of the series in a more in-depth manner.
I just double checked and he was actually in both the sequel and the third movie (I don't remember him making two appearances). I'll have to rewatch those films.
I'm also assuming you're talking about the Raimi trilogy.
