Context_1 : Miss Evers' Boys is a 1997 HBO television film starring Alfre Woodard and Laurence Fishburne, based on the true story of the decades-long Tuskegee experiment. It was directed by Joseph Sargent and adapted from the 1992 stage play written by David Feldshuh. The film was nominated for eleven Emmy Awards and won in four categories, including Outstanding Made for Television Movie. Context_2 : The Marsh Chapel Experiment, also called the "Good Friday Experiment", was a 1962 experiment conducted on Good Friday at Boston University's Marsh Chapel. Walter N. Pahnke, a graduate student in theology at Harvard Divinity School, designed the experiment under the supervision of Timothy Leary and the Harvard Psilocybin Project. Pahnke's experiment investigated whether psilocybin (the active principle in psilocybin mushrooms) would act as a reliable entheogen in religiously predisposed subjects. Context_3 : David Feldshuh (born 1944 in New York City) is a physician, playwright, and author. His 1992 play "Miss Evers' Boys", based on the Tuskegee syphilis experiment, was a finalist for the 1992 Pulitzer Prize for Drama. The 1997 HBO adaptation of "Miss Evers' Boys" (adapted by Walter Bernstein) was nominated for eleven Emmy Awards (winning four) and two Golden Globe Awards (winning one). Context_4 : The Tuskegee Study of Untreated Syphilis in the Negro Male, also known as the Tuskegee Syphilis Study or Tuskegee Syphilis Experiment ( ) was an infamous clinical study conducted between 1932 and 1972 by the U.S. Public Health Service. The purpose of this study was to observe the natural progression of untreated syphilis in rural African-American men in Alabama under the guise of receiving free health care from the United States government. Context_5 : The "N"th Country Experiment was an experiment conducted by Lawrence Livermore National Laboratory starting in May 1964 which sought to assess the risk of nuclear proliferation. The experiment consisted in paying three recent young physicists who had just received their PhDs, though had no prior weapons experience, to develop a working nuclear weapon design using only unclassified information, and with basic computational and technical support. "The goal of the participants should be to design an explosive with a militarily significant yield", the report on the experiment read, "A working context for the experiment might be that the participants have been asked to design a nuclear explosive which, if built in small numbers, would give a small nation a significant effect on their foreign relations." Context_6 : The kerplunk experiment was a famous stimulus and response experiment conducted on rats and demonstrates the ability to turn voluntary motor responses into a conditioned response. The purpose of the experiment was to get kinaesthetic feedback rather than guidance through external stimuli through maze learning. It was conducted in 1907 by John B. Watson and Harvey A. Carr and was named after the sound the rat made after running into the end of the maze. The study would help form a chain of responses hypothesis proposed by Watson. Context_7 : The Wu experiment was a nuclear physics experiment conducted in 1956 by the Chinese American physicist Chien-Shiung Wu in collaboration with the Low Temperature Group of the US National Bureau of Standards. The experiment's purpose was to establish whether or not conservation of parity ("P"-conservation), which was previously established in the electromagnetic and strong interactions, also applied to weak interactions. If "P"-conservation were true, a mirrored version of the world (where left is right and right is left) would behave as the mirror image of the current world. If "P"-conservation were violated, then it would be possible to distinguish between a mirrored version of the world and the mirror image of the current world. Context_8 : The Rosenhan experiment was an experiment conducted to determine the validity of psychiatric diagnosis. The experimenters feigned hallucinations to enter psychiatric hospitals, and acted normally afterwards. They were diagnosed with psychiatric disorders and were given antipsychotic drugs. The study was conducted by psychologist David Rosenhan, a Stanford University professor, and published by the journal "Science" in 1973 under the title "On being sane in insane places". It is considered an important and influential criticism of psychiatric diagnosis. Context_9 : The Belle experiment was a particle physics experiment conducted by the Belle Collaboration, an international collaboration of more than 400 physicists and engineers, at the High Energy Accelerator Research Organisation (KEK) in Tsukuba, Ibaraki Prefecture, Japan. The experiment ran from 1999 to 2010. Context_10 : The Davisson–Germer experiment was a physics experiment conducted by American physicists Clinton Davisson and Lester Germer in 1923–1927, which confirmed the de Broglie hypothesis. This hypothesis, advanced by Louis de Broglie in 1924, says that particles of matter such as electrons have wave-like properties. By demonstrating the wave–particle duality, the experiment was an important historical development in the establishment of quantum mechanics and of the Schrödinger equation. fact_1 :  His 1992 play "Miss Evers' Boys", based on the Tuskegee syphilis experiment, was a finalist for the 1992 Pulitzer Prize for Drama. fact_2 : The Tuskegee Study of Untreated Syphilis in the Negro Male, also known as the Tuskegee Syphilis Study or Tuskegee Syphilis Experiment ( ) was an infamous clinical study conducted between 1932 and 1972 by the U.S. Public Health Service. Answer: U.S. Public Health Service
Output: David Feldshuhs play Miss Evers Boys is based on an experiment conducted by who?
