Johann Georg Albrechtsberger (1736-1809) was a composer, organist, and music theorist. He was a contemporary of Joseph Haydn and was one of Ludwig van Beethoven’s teachers. The fugue in E minor (transposed to A minor here) is from his op. 1, 12 Fugues for Harpsichord or Organ, and was misattributed as a work by Johann Sebastian Bach (BWV 962).
