Edward Moore Zimmerman, often given as E. M. Zimmerman, (January 9, 1859 – December 6, 1922) was an American bass, composer, choir conductor, organist, and music educator.[2] A longtime resident of Philadelphia, he was active as a church and concert singer in that city from the 1880s into the early years of the 20th century. He also worked as a voice teacher in Philadelphia, and held posts as a choir conductor and organist at several churches in that city. He was also a vocal music instructor at the Methodist Conference Seminary (now The Pennington School). He is best remembered as a composer of hymns, and for co-writing the suffragist anthem "Votes for Women: Suffrage Rallying Song" (1915) with his wife and frequent singing partner, the soprano Marie Kunkel Zimmerman.
