Theodore Frelinghuysen Seward (1835-1902) was born in Florida, Orange County, New York, second cousin of U. S. Secretary of State, Senator, and NY Governor William H. Seward. He studied music under Lowell Mason and Thomas Hastings. He held organist positions in New London, Connecticut, and in Rochester, New York, before moving to New York City. His wife was a well known poet and activist Mary Holden Coggeshall Seward. He managed performances of the Fisk Jubilee Singers, wrote down more than one hundred of their plantation melodies, and toured Europe with them. He became interested in the British system of musical instruction, took a residency in England to study, and worked to establish the Tonic sol-fa system in the U.S. He wrote and lectured on the subject, taught the system in classes and public schools, and prepared a series of textbooks. He was the founder of the American tonic sol-fa Association, and of the American vocal music association. He also founded the Brotherhood of Christian Unity and the Don’t Worry Club. He died in East Orange, New Jersey.
