Who was Harry K. Daghlian, Jr.?

Haroutune Krikor Daghlian, Jr. was an Armenian American physicist with the Manhattan Project who accidentally irradiated himself on August 21, 1945, during a critical mass experiment at the remote Omega Site facility at Los Alamos National Laboratory in New Mexico, resulting in his death 25 days later.

Daghlian was irradiated as a result of a criticality accident that occurred when he accidentally dropped a tungsten carbide brick onto a 6.2 kg delta phase plutonium bomb core. This core, available at the close of World War II and later nicknamed the "Demon core", also resulted in the death of Louis Slotin in a similar accident, and was used in the Able detonation, during the Crossroads series of nuclear weapon testing.
