Mary Clarissa "May" Byron (1861 – 1936) was a British writer and poet, best known for her abridgements of J. M. Barrie's Peter Pan books. She published under the names May Byron, M.C. Gillington and Maurice Clare. Byron specialized in writing biographies of great artists, before going on to rewrite some of J. M. Barrie's works for younger readers and to write cookbooks.
“A Day with Robert Schumann” by Mary Byron is written during the 1910s in the belles lettres style that provides the reader a brief escape into the life and mind of a great German composer and influential music critic Robert Schumann. It includes part research, part supposition, part imagination accompanying a fictional April morning in 1844, the town of Leipzig,— calm, cool, and fraught with exquisite promise of a prolific spring in life of Robert Schumann. The work includes poetry selections and color illustrations written under the pseudonym "Maurice Clare".
