Those who fail to study history are
condemned to repeat it.

Tuskegee Syphilis Study - Timeline
  KEY DATES: 1926, 1931, 1932, 1940, 1945, 1972, and 1997

1895 Booker T. Washington at the Atlanta Cotton Exposition, outlines
his dream for black economic development and gains support of
northern philanthropists, including Julius Rosenwald (President of
Sears, Roebuck and Company).

1900 Tuskegee educational experiment gains widespread
support. Rosenwald Fund provides monies to develop schools,
factories, businesses, and agriculture.

1915 Booker T. Washington dies; Robert Motin continues work.

1926 Health is seen as inhibiting development and major health
initiative is started. Syphilis is seen as major health problem.
Prevalence of 35 percent observed in reproductive age population.

1929 Aggressive treatment approach initiated with mercury and
bismuth. Cure rate is less than 30 percent; treatment requires months
and side effects are toxic, sometimes fatal.

1929 "Wall Street Crash"--economic depression begins.
1931 Rosenwald Fund cuts support to development projects. Clark
and Vondelehr decide to follow men left untreated due to lack of funds
in order to show need for treatment program.

1932 Follow-up effort organized into study of 399 men with syphilis
and 201 without. The men would be given periodic physical
assessments and told they were being treated. Motin agrees to
support study if " Tuskegee gets its full share of the credit" and black
professionals are involved (Dr. Dibble and Nurse Rivers are assigned
to study).

1934 First papers suggest health effects of untreated syphilis.

1936 Major paper published. Study criticized because it is not known
if men are being treated. Local physicians asked to assist and asked
not to treat men. It was also decided to follow the men until death.

1940 Efforts made to hinder men from getting treatment ordered
under the military draft effort.

1945 Penicillin accepted as treatment of choice for syphilis.

1947 USPHS establishes "Rapid Treatment Centers" to treat syphilis;
men in study are not treated, but syphilis declines.
1962 Beginning in 1947, 127 black medical students are
rotated through unit doing the study.

1968 Concern raised about ethics of study by Peter Buxtun
and others.

1969 CDC reaffirms need for study and gains local medical
societies' support (AMA and NMA chapters officially
support continuation of study).

1972 First news articles condemn studies.

1972 Study ends.
1973 Congress holds hearings and a class-action lawsuit is
filed on behalf of the study participants.

1974 A $10 million out-of-court settlement is reached and
the U.S. government promised to give lifetime medical
benefits and burial services to all living participants. The
Tuskegee Health Benefit Program (THBP) was established
to provide these services.

1975 Wives, widows and offspring were added to the

1995 The program was expanded to include health as well
as medical benefits.

1997 On May 16th President Clinton apologizes on behalf
of the Nation.
