Emilie Mayer (1812-1883) was a German composer, quite successful in her day. Among her compositions are 8 symphonies, a piano concerto, several concert overtures and much chamber music. Her most famous teacher was Carl Loewe, remembered today mostly for his lieder.
Her Symphony No. 7 is impressive and very Schumannesque.
