[2] In the period 1939–1942 he carried out post-doctoral research in the Harvard Medical School, where he worked on determination of haemoglobin in tissue extracts.

[3] From 1942 he participated in the Manhattan Project, working initially at the University of Chicago, but after 1943, and for the rest of his career, at Oak Ridge, Tennessee.

[4] On account of the secrecy attached to the Manhattan Project, Cohn published rather little during this period, but that included the start of a long-term interest in nucleic acids.

[6] Cohn was an accomplished cellist, and created the Oak Ridge Symphony Orchestra, which held its first concerts in 1944, with early soloists including Isaac Stern, Yaltah Menuhin and Percy Grainger.

[10] His brother Roy (not to be confused with the notorious lawyer of the same name) worked as a chemist in the paint industry in the San Francisco Bay Area.
