A person who burkes; someone who suppresses something quietly or historically, a person who commits smothering murders as William Burke did.
From the verb 'burke' (derived from William Burke's name) plus the agent suffix '-er'. Created in the 19th century as the crime and its suppression became well-known.
Victorian newspapers sensationalized Burke's murders so intensely that 'burker' became slang for any suspicious person or murderer in the 1820s-30s, showing how quickly crime could capture public imagination before modern media.
