This replica of Peyton Rous’ interval calculator was made for Merrill Chase around 1958 by the Instrument Shop.
Peyton Rous, in addition to his discovery of a cancer-causing virus (he received a Nobel Prize for this discovery in 1966), is remembered for developing a method for preserving whole blood for transfusion, and for the high standards of scientific exposition he maintained during more than six decades of research.
