Malcolm C Duncan

Malcolm C. Duncan was a 19th-century American Freemason best known for writing *Duncan's Ritual of Freemasonry*, a widely used reference on Masonic ceremonies, symbolism, and practice. Available sources consistently describe him as an influential author in Masonic literature, but they provide limited reliable biographical detail beyond his association with Freemasonry and his works.
