The 30s, 40s, and 50s in Puerto Rico were turbulent time periods as the U.S. stripped Puerto Rico of its civil rights, culture, language, governance, and relations and commerce with other countries. This included the involuntary sterilization of Puerto Rican women, the militarization of the island, and using parts of the Puerto Rico archipelago for bombing practices. The peaceful Palm Sunday, which resulted in murders caused by the military police, known as the “Ponce Massacre,” was reminiscent of Ireland’s “Bloody Sunday.” During this time period, Dr. Cornelius P. Rhoads, a Harvard Medical School graduate, wrote in a letter that he was conducting cancer research and experimenting by injecting Puerto Ricans with cancer cells.
