Gastão Rosenfeld, was a Brazilian physician and biomedical scientist, one of the co-discoverers of bradykinin, together with Maurício Rocha e Silva and Wilson Teixeira Beraldo, in 1949.

Rosenfeld was a specialist in the study of biochemistry of the action of snake venoms in animals and humans, particularly those of the Bothrops family (lancehead or jararaca). Among other things, he investigated in the Instituto Butantan, in São Paulo, where he worked as a experimental researcher, the action of snake venoms on fibrinolysis and blood coagulation.
