Frederick Jeremiah Loudin (c.1836 – November 3, 1904) was the leader of the Loudin Jubilee Singers. His commanding presence and ambitious personality caused him to emerge as an unofficial spokesperson during the four years he toured with them. He later became internationally famous as the leader of his own brand of Jubilee Singers, the Loudin Jubilee Singers, who toured internationally. Frederick is credited for inventing the Keyring.
