This theme comes from the second movement (allegretto) from the 7th symphony by Beethoven. He composed the 7th symphony between 1811-1812. Beethoven conducted the premiere in 1813 and the audience loved the piece so much they played the second movement as an encore. This theme is one of my favorites of his.
