In the first century of its existence the entire reception history of the Toccata and Fugue in D minor consists of being saved from oblivion by maybe not more than a single manuscript copy. Then it took about a century from its first publication as a little known organ composition by Johann Sebastian Bach to becoming one of the signature pieces of the composer. The composition's third century took it from Bach's most often recorded organ piece to a composition with an unclear origin. Despite Mendelssohn's opinion that it was "at the same time learned and something for the people", followed by a fairly successful piano transcription in the second half of the 19th century, it was not until the 20th century that it rose above the average notability of an organ piece by Bach. Leopold Stokowski's orchestration, featured in the 1940 Walt Disney film "Fantasia", appears to have been instrumental in assuring its status as an evergreen by the 1980s, around which time scholars started to seriously doubt its attribution to Bach.
