Potioncat:
Actually, now that you mention it:
We know how long McGonagall's been teaching at Hogwarts but we don't 
know if she's always taught Transfigurations or when she became Head 
of Gryffindor or when she became Deputy Headmistress.

As far as I'm concerned, we don't know that DD was on staff the 
entire time after Tom Riddle was a student. He could have left 
Hogwarts either completely or been on leave for a number of years.

I suspect, based on canon, but not confirmed, that MM replaced DD as 
Transfiguration teacher. I don't think it was ever said that DD was 
a Head of House or a Deputy Headmaster. We know that DD became 
Headmaster shortly before the Marauders came, but we do not know who 
his Deputy was nor who the Heads of Gryffindor and Slytherin were at 
that time. We do know that it isn't a requirement to be on staff to 
become Headmaster. Headmistress Derwent (I hope I spelled that 
correctly.) was a Healer at St. Mungo's prior to becoming 
Headmistress.
