Years and years ago, I went to a lecture by a biographer of Bram Stoker, whose 165th birthday is today. (He gets his own Google Doodle at that link.)
It was a fairly interesting chat and I asked him about blood transfusions. In 1897, blood typing and transfusions were in their infancy and I wondered how Abraham knew so much about them. I was told that Bram's brother was a doctor and was researching transfusions. A lot of Stoker's Dracula novel was given credence by such authenticity.
Here are some highlights from Coppola's adaptation of Bram Stoker's most famous book.
Happy Birthday Bram!
