Some very famous composers who wrote important cello music were: Mendelssohn, Chopin, Schumann, Brahms, Dvořák, Fauré, Saint-Saëns, Elgar, Sergei Rakhmaninov.  Two  famous pieces written more recently for cello and orchestra are the Cello Symphony by Benjamin Britten  and The Protecting Veil by John Tavener.
