Who taught DADA before Quirrell?

      So, maybe Voldemort lifted his own curse on the DADA job to 
 give his servant more than one year to do his dirty work at Hogwarts. 
Assuming, of course that he was in Voldemort's employ when he was 
 firsthired at Hogwarts.
 IMO it was not Voldemort's curse that killed Quirrel, it was 
Voldemort himself. 

Marianne S:

My thoughts on Quirrell and the Curse and the fact he was not
introduced as "new" might be explained/justified this way:

Just-Quirrell was DADA teacher for the year before Harry arrived. 
By the time he returned for Harry's first year, he was not
really himself but "Voldemort-in-Turbin-Quirrell." That way,
the curse still applies because we know it was the summer
before Harry started that Quirrell met up with Soul-Fragment-
Voldemort,and it was after the Gringotts' botched break-in
incident that Voldemort took up inhabitance in Quirrell's 
head/turbin. That would be the first manifestation of the
curse, and Voldemort leaving Quirrell to die at the 
end of Harry's first year would be the second one. 

Perhaps it really was just an oversight on JKR's part, but I'm 
satisfied with my interpretation.
