Most important piano composers before 1950?

[kosulin]

Hi all,
I have a small but very long lasting project for myself - to learn at least one solo piano piece from each of the most important keyboard composers of the past (including the first half of the 20th century).
Please comment on the chart below - have I missed somebody or overestimated some? Busoni, Siloti, Schoenberg, etc.? Some entries, like Reicha, are just my personal favorites. And I am not very knowledgeable with 20th century composers, American and Asian ones, could easily miss somebody. Also, I not a very big fan of modernism (atonal, stochastic, etc.), and I also intentionally dropped (at least for now) very early keyboard/harp composers, because the list is very long already.

Here's what I can think of off the top of my head (use them at your own discretion)
Baroque: Gibbons, Soler, Galuppi
Classical: Dussek, Kuhlau, J.C. Bach
Romantic: Raff, Hummel, Moszkowski, Reger, Arensky
20th Century: Coleridge-Taylor, Janacek, Boulanger, Shostakovich, Szymanowski, Gershwin, Copland

Here's a few more of composers which I have listened to and think are worth exploring (and are not on your or <transitional>'s list)

Carter, Elliot
Feinberg, Samuil (great sonatas, neglected but worthy)
Godowsky (his Java Suite, Passacaglia, Sonata, etc)
Hindemith (sonatas)
Ireland, John
Messiaen
Mompou, Frederic
Ornstein, Leo (some remarkable pieces)
Roslavets (neglected, but worthy)

I think you are missing

Cesar Franck
His contribution in terms of quantity is very small, but he has written some very significant pieces in the repertoire, such as the "Prelude, Chorale and Fugue" and the Sonata for Violin and Piano.

Manuel de Falla is as important as Albeniz and Granados whom you already have on your list. Many Spaniards consider him the most important of the three.

Thank you folks for your replies.
Some names I just forgot somehow, and for some I need to look deeper into.
Some like Shostakovich were excluded because they fall for me at mid and later 20th Century.
I added de Falla, BTW, not sure why I skipped him in the first place. Probably because he associates for me with songs more than with solo piano. Same for Mompou.

kosulin, you may also want to check Piano Street's sheet music library to see who else you missed.

Surprised no one has mentioned Balakirev or Alkan. Also, is Mereaux on there?
