A short quiz for cello experts:
1) name a famous violinist and composer who left 2 fine cello concertos.
2) name an englishman who wrote a Symphony for cello and orchestra.
3) name a cellist and composer of operettas and some film music who left romantic cello concertos.
4) name a modern russian who left 2 very beautiful and romantic cello sonatas.
5) name a jewish virtuoso cellist and composer of 4 very difficult cello concertos.
6) name who composed a sonata-fantasia for solo cello.
7) name a very famous pianist who left an exceedingly queer cello concerto.

Prokofiev ?

It could be any Russian; it just depends on the reader's definitions of modern and beautiful.

"Modern" applies to the composer; not the works,that are totally romantic.

Benjamin Britten, that's the only one I'm sure I know.

Lloyd Webber, perhaps?

Mischa Mayski?

J.S. Bach, I suppose. (I probably suppose wrongly...)

No.2), YES! Britten. A very, very difficult piece

The rest, no. Sorry.

1. I'm tempted to say Vieuxtemps again, but I'll say Ysaye this time.

Or maybe Wieniawski.

YES sir, Vieuxtemps!. 2 lovely cello concerti. You should follow your tentations. After all,like OW used to say; "I can resist everything, except tentation".
And Wieniawsky (Henri) didn't wrote nothing except for violin. His brother, Joseph, a
pianist and unknown composer, had a cello sonata.

Ah, well, I suppose you can't have everything... particularly when entering the realms of guesswork.

OK, 7th.you'll never answer. It was Friedrich Gulda. His cello concerto is the
craziest piece I ever heard. And awfully difficult. That's why nobody ever
plays it live. Only know one recording.

OK, it seems that you don't care much for the cello, so let's finish this:

3) Victor Herbert

4) Nicolai Miaskovski

5) David Popper

6) Khatchaturian

Bye Bye..

Not me. It's just that I'm getting to know many of the composers/performers only through the quizzes of yours.

Well, as a fanatic collector of rarities, I could name a lot of other unknown and/or
forgotten composers and works, but I don't want to bore you.

I recently discovered the piano sonatas of this fellow and was blown away; so thank you for noting his two cello sonatas because I'll definitely check them out.

Lay them on us - it's always good to have some neglected composers queued up for exploration. I have my fair share at the moment, but who else outside the standard composer pantheon could you recommend for, say... Romantic violin sonatas?

Romantic violin sonatas?. Sure thing:

Franck
Saint-Saëns first (try to get Heifetz!)
Guillomme Lekeu (Ferras or Menuhin)
Faure first (Francescatti-Casadesus)
Karl Goldmark
Josef Foerster
GRIEG! (the 3 of it)
Dvorak (Josef Suk)
Schumann
Dohnanyi
Richard Strauss (Heifetz)
Mendelssohn
Respighi (Heifetz again!)
That's enough for starters
