Which op 14 sonata is this - #1 or #2?
I have to check my urtext edition, but I don't think Bethoven put pedal marking indications in many of his earlier composition, so I would bet that is an editor's marking. Which edition are you using?
Beethoven made only about 30-40 pedal markings in all his piano compositions - 32 sonatas, sets of variations, etc. He used the damper pedal a lot, and his pedal markings appear in his music to indicate his desire to pedal where most people would not use the pedal. In other words, if you do not see a pedal marking in an urtext edition, that does not mean it is wrong to use it.
