Eddie died a month before his fourth birthday. Although census records list "chronic consumption" (tuberculosis) as the cause, cardiologist John Sotos has suggested that Eddie died of medullary thyroid cancer given that: (a) "consumption" was a term then applied to many wasting diseases, (b) cancer is a wasting disease, (c) his father and two of his brothers had several features compatible with the genetic cancer syndrome multiple endocrine neoplasia type 2b (MEN2B), (d) Eddie's thick, asymmetric lower lip is a sign of MEN2B, and (e) 100% of persons with MEN2B develop medullary thyroid cancer, sometimes as early as the neonatal period.
