Composer known as the "Father of the Symphony" (5)

I believe the answer is:

haydn

(Other definitions for haydn that I've seen before include "Austrian composer of over one hundred symphonies" , "Joseph -, prolific eighteenth to nineteenth century Austrian composer" , "Josef --, prolific composer" , "Creation composer" , "Austrian musician" .)

I've seen this clue in the LA Times.
