Blood Fractionation Project
Cohn became famous for his work on blood fractionation during World War II. In particular, he worked out the techniques for isolating the serum albumin fraction of blood plasma, which is essential for maintaining the osmotic pressure in the blood vessels, preventing their collapse. Transfusions with purified albumin on the battlefield rescued thousands of soldiers from shock.
After the war, Cohn worked to develop systems by which every component of donated blood would be used, so that nothing would be wasted.
On Cohn's office blackboard was inscribed a quotation from Goethe's Faust: "Das Blut ist ein ganz besonderer Saft." (Blood is a very special juice.)

Famous quotes containing the words blood and/or project:
“His white head hung out like a carpet bag
and his crotch turned blue as a blood blister,
and Godfather death, as it is written,
put a finger on his back
for the big blackout,
the big no.”
—Anne Sexton (1928–1974)
“From a bed in this hotel Seargent S. Prentiss arose in the middle of the night and made a speech in defense of a bedbug that had bitten him. It was heard by a mock jury and judge, and the bedbug was formally acquitted.”
