On 23 March 1945 Ebb Cade was on his way to work at a construction site for the Manhattan Project when he was involved in a traffic accident at Oak Ridge, Tennessee. He was an African-American cement worker for the J.A. Jones Construction Company. Cade presented at the Oak Ridge Hospital with fractures of right patella, right radius and ulna and left femur. Dr. Hymer Friedell, deputy medical director of the Manhattan Engineer District, determined that as Cade was, as he characterized, a "well developed..well nourished" "colored male", he was suitable for "experimentation" with plutonium injection. Doctors left his fractures untreated for 20 days until after plutonium injections began on 10 April 1945. Cade received the injections at the Oak Ridge Hospital on the Clinton Engineer Works reservation at Oak Ridge, Tennessee without his assent or knowledge. He became known as HP-12 (Human Product-12), and was the first person to be injected with Pu-239. In order to test the migration of plutonium through his body, subsequently fifteen of Cade's teeth were extracted, and bone samples taken.
