Historically, only full professors could have a specific chair, and assistant and associate professors could only wonder under supervision of a chaired (full) professor.

Now, every assistant professor is an independent academic, only with a lower salary and possibilities. On the other hand, a chaired position gains secured research funding, but no other faculty member is under his supervision (yes or no, this is my question).

I think the classic chair system still exists in Japan (at least to some extent). Do universities in West Europe and North America still have such system to place junior faculty members (assistant/associate professors) under supervision of a senior (chaired professor) faculty member?
