Which composer is associated with both the Piano Sonata in C Minor and the Symphony No. 5?

Ludwig van Beethoven is the composer associated with both the Piano Sonata in C Minor and the Symphony No. 5. The Piano Sonata in C Minor, Op. 13, famously known as the "Pathétique" Sonata, was composed by Beethoven and is renowned for its emotional depth and innovative structure. It showcases Beethoven's ability to convey profound feelings through his music, which became a hallmark of his style.

Similarly, Symphony No. 5, also by Beethoven, is one of the most recognizable symphonies in Western classical music. Its famous four-note motif—short-short-short-long—is often interpreted as a representation of fate knocking at the door. Both works exemplify Beethoven's pioneering spirit and his transition to the Romantic period, making him a central figure in classical music history.
