Can someone help me

I'm looking for sources about how Haydn influenced Beethoven. Anyone knows how he influenced beethoven? in what ways? I couldn't find any good sources and it most likely haydn and mozart.

Try googlebooks. If you are familiar with Beethoven's sonatas, just listen to the last twenty Haydn sonatas. The "influence" is blatant in most of them. For instance, compare the first movement of Hob. XVI Sonata No. 47 with the first movement of Beethoven's Op. 22 sonata.

The Pastoral sonata (Opus 28) is also sometimes called the Hadyn sonata, but for the life of me I can't quite remember why. It does show the "trademark" Haydn 'scherzo' as a movement. Maybe that was the reason.
