Harlow Shapley (November 2, 1885 – October 20, 1972) was an American astronomer, who served as head of the Harvard College Observatory from 1921–1952, and political activist during the latter New Deal and Fair Deal.
Shapley used Cepheid variable stars to estimate the size of the Milky Way Galaxy and the Sun's position within it.Bart J. Bok. Harlow Shapely 1885–1972 A Biographical Memoir. National Academy of Sciences In 1953 he proposed his "liquid water belt" theory, a concept now known as a habitable zone.Richard J. Hugget, Geoecology: An Evolutionary Approach. p. 10
In 1907, Shapley went to the University of Missouri to study journalism. When he learned that the opening of the School of Journalism had been postponed for a year, he decided to study the first subject he came across in the course directory. Rejecting Archaeology, which Shapley later claimed he could not pronounce, he chose the next subject, Astronomy.
He realized that the Milky Way Galaxy was far larger than previously believed, and that the Sun's place in the galaxy was in a nondescript location. This discovery supports the Copernican principle, according to which the Earth is not at the center of the Solar System, the Milky Way galaxy, nor the Universe.
Characteristic issues were whether Adriaan van Maanen had measured rotation in a spiral nebula, the nature and luminosity of the exploding novae and supernovae seen in spiral galaxies, and the size of the Milky Way. However, Shapley's actual talk and argument given during the Great Debate were completely different from the published paper. Historian Michael Hoskin says "His decision was to treat the National Academy of Sciences to an address so elementary that much of it was necessarily uncontroversial", with Shapley's motivation being only to impress a delegation from Harvard who were interviewing him for a possible offer as the next Director of Harvard College Observatory."The 'Great Debate': What Really Happened" Hoskin, M., Journal for the History of Astronomy, 7, 169 (1976) With the default by Shapley, Curtis won the debate. The astronomical issues were soon resolved in favor of Curtis' position when Edwin Hubble discovered Cepheid variable stars in the Andromeda Galaxy.
At the time of the debate, Shapley was working at the Mount Wilson Observatory, where he had been hired by George Ellery Hale. After the debate, however, he was hired to replace the recently deceased Edward Charles Pickering as director of the Harvard College Observatory (HCO).
Despite having earlier argued strongly against the idea of galaxies other than the Milky Way, Shapley went on to make significant progress in the research of the distribution of galaxies, working between 1925 and 1932. In this time period, with the Harvard College Observatory, he worked to map 76,000 galaxies. One of the first astronomers to believe in the existence of galaxy superclusters, Shapley later discovered a large and distant example, which was later named the Shapley Supercluster. He estimated the distance to this supercluster at 231 Mpc, which is within 15% of the currently accepted value.
From 1941 he was on the original standing committee of the Foundation for the Study of Cycles. He also served on the board of trustees of Science Service, now known as Society for Science & the Public, from 1935 to 1971.
On November 14, 1946, Shapley appeared under subpoena by the House Committee on Un-American Activities (HCUA) in his role as member of the Independent Citizens Committee of the Arts, Sciences and Professions (ICCASP), which HCUA described as a "major political arm of the Russophile left". It had opposed re-election of U.S. Representative Joseph William Martin Jr. during mid-term elections that year and was asked to answer questions about the ICCASP's Massachusetts' chapter. HCUA committee chairman John E. Rankin commented about Shapley's attitude, "I have never seen a witness treat a committee with more contempt" and considered contempt of Congress charges. Shapley accused HCUA of "Gestapo methods" and advocated for its abolition, saying that it had made "civic cowards of many citizens" by pursuing the "bogey of political radicalism."
A few weeks later, in early 1947, Shapley became president of the American Association for the Advancement of Science (AAAS). At the time, the AAAS's choice appeared to be a "rebuke" of HCUA and a positive championing of scientists. In his inaugural address, Shapley referred to the danger of the "genius maniac" and proposed the elimination of "all primates that show any evidence or signs of genius or even talent" (a suggestion that was apparently tongue-in-cheek). Four other global threats he listed were: drugs that suppressed the desire for sex, boredom, a world war with weapons of mass destruction, and a plague epidemic.
In March 1949, Shapley chaired the Cultural and Scientific Conference for World Peace at the Waldorf-Astoria in Manhattan. It was sponsored by the National Council of Arts, Sciences and Professions. Arch-conservative William F. Buckley, Jr., authored a 1951 book, wherein, in the eve of McCarthyism, he attacked liberalism at Yale University and academia in general. In the book, Buckley cited Shapley's participation and averred that event was "Communist-inspired" and "Russian-dominated."
In 1950, Shapley was instrumental in organizing a campaign in academia against Worlds in Collision by expatriate psychiatrist Immanuel Velikovsky. Scientists generally considered this controversial US bestseller to be pseudoscience.
They had one daughter, editor and writer Mildred Shapley Matthews; and four sons. These included Lloyd Shapley, a mathematician and economist who won a Nobel Memorial Prize in Economics in 2012, and Willis Shapley, who became a Senior Executive Service leader at NASA. His eldest granddaughter, June Lorraine Matthews, became a physicist.
Although Shapley was an agnostic, he was greatly interested in religion.
Shapley died in a nursing home in Boulder, Colorado on October 20, 1972, shortly before his 87th birthday.
Before the anti-communist phrase "Better Dead Than Red" became popular during McCarthyism in the 1950s, Shapley said in a 1947 speech entitled "Peace or Pieces" that "A slave world is not worth preserving. Better be lifeless like the cold moon, or primitively vegetal like desolate Mars, than be a planet populated by social robots."
In 1953, he wrote the "Liquid Water Belt" which gave scientific credence to the Habitable zone theory of Hubertus Strughold.James F. Kasting, How to find a habitable planet. p. 127
In his 1957 book Of Stars and Men, Shapley proposed the term Metagalaxies for what are now called .
Shapley attended Institute on Religion in an Age of Science conferences at Star Island and was the editor of the book Science Ponders Religion (1960)."Varieties of Belief" (Review of Science Ponders Religion) by Edmund Fuller, December 18, 1960, The New York Times.
Global policy
He was one of the signatories of the agreement to convene a convention for drafting a world constitution. As a result, for the first time in human history, a World Constituent Assembly convened to draft and adopt the Constitution for the Federation of Earth.
Personal life
Shapley married Martha Betz (1890–1981) in April 1914, whom he had met in Missouri. She assisted her husband in astronomical research both at Mount Wilson and at Harvard Observatory. She wrote numerous articles on eclipsing stars and other astronomical objects.

Works
Shapley wrote many books on astronomy and the sciences. Among these was Source Book in Astronomy (New York: McGraw–Hill, 1929, co-written with Helen E. Howarth, also on the staff of the Harvard College Observatory), the first of the publisher's series of source books in the history of the sciences.
