P. T. Barnum: P. T. Barnum was an American showman and politician who built a celebrated museum and traveling circus. Barnum’s publicity culture helped establish the nineteenth-century sideshow tradition in which Corbin performed.
Dipygus: Dipygus is a rare congenital malformation involving duplication of the lower body, typically including the pelvis and legs. This is the specific condition associated with Corbin’s duplicated lower body.
Medical case report: A medical case report is a detailed account of an individual patient's symptoms, diagnosis, treatment, or anatomy. Physicians documented Corbin’s anatomy in a form used to describe unusual clinical cases.
Polymelia: Polymelia is a congenital condition in which a person has one or more extra limbs. Unlike Corbin’s duplicated lower-body structures, polymelia primarily describes additional limbs.
Chang and Eng Bunker: Chang and Eng Bunker were conjoined twins from Siam who became internationally known performers and later settled in the United States. Their fame helped make bodily difference a central draw in American sideshows before Corbin’s career.
Conjoined twins: Conjoined twins are identical twins physically connected at birth because their embryos did not fully separate. Dipygus is often discussed alongside forms of incomplete embryonic separation and twinning.
Medical humanities: Medical humanities examines medicine through history, literature, ethics, and the arts. Corbin’s story raises questions about how medical description and public spectacle framed disability.
Sirenomelia: Sirenomelia is a rare congenital condition in which the legs are fused to varying degrees. It alters the lower limbs in the opposite structural direction from Corbin’s duplication.
Julia Pastrana: Julia Pastrana was a nineteenth-century performer whose hypertrichosis and other features were exhibited in Europe and North America. Her career shows how sideshows turned unusual bodies into marketed public spectacles.
Embryonic development: Embryonic development is the process by which a fertilized egg forms the tissues and organs of an organism. The origins of congenital body duplication lie in early developmental processes.
