[A matter of heart--two examinations of the same heart with a sixty year interval].

The 20th of May 1869, Professor Emanuel Winge used a human heart as an exhibit at a meeting of The Medical Society in Christiania. This heart was later conserved and kept in the museum of the Institute of Pathology. Sixty years later, one of Winge's successors, Professor Francis Harbitz, used the very same heart, also at a meeting of The Medical Society. Harbitz had then confirmed Winge's hypothesis of 1869, that the endocarditis of this heart was due to a bacterial infection. This article contemplates the disparity between the "scientific gazes" of Winge and Harbitz, and why Harbitz was able to convert Winges hypothesis of 1869 into a scientific discovery in 1929.
