The amazing music channel Listening In looks at classical musicians with synesthesia, in particular Kandinsky, and how he created such musical art.

The US Medical Establishment experimenting on its citizens is nothing new. After all, the word vaccine comes from 'vacca'; Latin for cattle. --- The Tuskegee Syphilis Experiment was an infamous clinical study conducted between 1932 and 1972 by the U.S. Public Health Service studying the natural progression of untreated syphilis in rural African-American men in Alabama under the auspices of receiving free health care from the United States government. The Public Health Service started working on this study in 1932 during the Great Depression, in collaboration with Tuskegee University, a historically black college in Alabama. Investigators enrolled in the study a total of 600 impoverished, African American sharecroppers from Macon County, Alabama. Of these men, 399 had previously contracted syphilis before the study began, and 201 did not have the disease. The men were given free medical care, meals, and free burial insurance for participating in the study. After funding for treatment was lost, the study was continued without informing the men they would never be treated. None of the men infected were ever told that they had the disease, and none were treated with penicillin even after the antibiotic became proven for the treatment of syphilis. According to the Centers for Disease Control, the men were told they were being treated for "bad blood", a local term for various illnesses that include syphilis, anemia, and fatigue. The 40-year study was controversial for reasons related to ethical standards because researchers knowingly failed to treat patients appropriately after the 1940s validation of penicillin as an effective cure for the disease they were studying. Revelation in 1972 of study failures by a whistleblower led to major changes in U.S. law and regulation on the protection of participants in clinical studies. Now studies require informed consent communication of diagnosis, and accurate reporting of test results. By 1947, penicillin had become the standard treatment for syphilis. Choices available to the doctors involved in the study might have included treating all syphilitic subjects and closing the study, or splitting off a control group for testing with penicillin. Instead, the Tuskegee scientists continued the study without treating any participants; they withheld penicillin and information about it from the patients. In addition, scientists prevented participants from accessing syphilis treatment programs available to other residents in the area. The study continued, under numerous US Public Health Service supervisors, until 1972, when a leak to the press resulted in its termination on November 16 of that year. The victims of the study, all African American, included numerous men who died of syphilis, 40 wives who contracted the disease, and 19 children born with congenital syphilis. The Tuskegee Syphilis Study, cited as "arguably the most infamous biomedical research study in U.S. history", led to the 1979 Belmont Report and the establishment of the Office for Human Research Protections (OHRP). It also led to federal laws and regulations requiring Institutional Review Boards for the protection of human subjects in studies involving them. The Office for Human Research Protections (OHRP) manages this responsibility within the US Department of Health and Human Services (HHS). https://infogalactic.com/info/Tuskegee_syphilis_experiment
