One-Hit Wonder in classical music

Hello, the question is meant rather ironically.
Who would you describe as a one-hit wonder in classical music? In other words, someone who had a mega hit but is hardly known for anything else.
Every case is open to debate, of course, and I don't want to front anyone.

I'll start with Johann Pachelbel. Canon in D is great and incredibly well-known, is played at many weddings etc. But after that there was nothing more by Pachelbel, at least nothing that big in my opinion.
