[The unexplained death of Blandine Liszt Ollivier]

Franz Liszt's eldest daughter, Blandine Ollivier, died at the age of 26, two months after the birth of her son Daniel. The reasons of that death remain obscure. There are contradictions between the asserted good health of Blandine during her pregnancy and what was learnt later on through the publication in French of Richard Wagner's autobiography. He was the husband of Cosima who was herself Blandine's sister. We put forward some hypotheses that can be discussed; Blandine would have contracted a serious anemia of pregnancy, unknown, with a streptococcus septicemia in post partum; no sign or symptom in consideration of mastitis carcinosis.
