November 1929 The Rosenwald Fund votes to spend up to $50,000 from January through December of 1930 for syphilis control demonstration programs.  The Public Health Service (PHS) recommends six locations for the program: Macon County, Alabama; Scott County, Mississippi; Tipton County, Tennessee; Glynn County, Georgia; Pitt County, North Carolina; Albemarle County, Virginia.
February 1930 —
September 1931
The Rosenwald Fund syphilis control program in progress in Macon County, Alabama. 39.8% are presumed to test positive for syphilis. 1400 men, women, and children are treated; 3684 are tested.
May 1930 Dr. H. L. Harris, Jr. makes a site visit for the Rosenwald Fund to Macon County.
Fall 1930 Harris visits the Macon County site again, questions the procedures, and recommends a comprehensive health plan be implemented.  It is not because the Rosenwald Fund cannot afford to continue the project nor can expand it beyond September 1931.

October 1932 The PHS study of untreated late latent syphilis begins in Macon County. The projected length of the study is 6-8 months and is supposed to include black men at least 25 years old who receive positive blood tests, have syphilis for at least five years (determined by onset of chancres), and who have not been treated. Not all the Study subjects meet this criterion. Subjects are then administered less than the recommended amount of therapy. Both men and women are being treated although men's names are selected for the Study.
May 1933 The Study’s men are subjected to spinal taps to diagnose neurological syphilis.
June 1933 Dr. Taliaferro Clark retires from the PHS; Dr. Raymond A. Vonderlehr succeeds him as head of the venereal disease division and continues the Study.  Autopsies are added to the Study. Men are now given aspirin, protiodide, and iron tonics.
