Members of the American Philosophical Society

Owen Jay Gingerich (; March 24, 1930 – May 28, 2023) was an American astronomer who had been professor emeritus of astronomy and of the history of science at Harvard University and a senior astronomer emeritus at the Smithsonian Astrophysical Observatory. In addition to his research and teaching, he had written many books on the history of astronomy.
Gingerich was also a member of the American Academy of Arts and Sciences, the American Philosophical Society, and the International Academy of the History of Science. A committed Christian, he had been active in the American Scientific Affiliation, a society of evangelical scientists. He served on the board of trustees of the Templeton Foundation.

Gustave-Adolphe Hirn (21 August 1815 – 14 January 1890) was a French physicist, astronomer, mathematician, and engineer who made important measurements of the mechanical equivalent of heat and contributions to the early development of thermodynamics. He further applied his science in the practical development of steam engines.

David Riesman (September 22, 1909 – May 10, 2002) was an American sociologist, educator, and best-selling commentator on American society.

Lloyd Viel Berkner (February 1, 1905 in Milwaukee, Wisconsin – June 4, 1967 in Washington, D.C.) was an American physicist and engineer. He was one of the inventors of the measuring device that since has become standard at ionospheric stations because it measures the height and electron density of the ionosphere. The data obtained in the worldwide net of such instruments were important for the developing theory of short wave radio propagation to which Berkner himself gave important contributions.
Berkner was elected to the United States National Academy of Sciences in 1948.Later he investigated the development of the Earth's atmosphere. Since he needed data from the whole world, he proposed the International Geophysical Year in 1950. At that time, the IGY was the largest cooperative study of the Earth ever undertaken.
Berkner was elected a Fellow of the American Academy of Arts and Sciences and a member of the American Philosophical Society in 1956. The IGY was carried out by the International Council of Scientific Unions while he was president in 1957–1959. He was also a member of the President's Scientific Advisory Committee in 1958 while he was president of Associated Universities Inc.
In 1963, Berkner, with L.C. Marshall, advanced a theory to describe the way in which the atmospheres of the Solar System's inner planets had evolved.
Beginning in 1926, as a naval officer, Berkner assisted in the development of radar and navigation systems, naval aircraft electronics engineering, and studies that led to the construction of the Distant Early Warning system, a chain of radar stations designed to give the United States advance warning in the event of a missile attack across the North Pole. In the 50s and 60s, Berkner held intelligence clearances in the Atomic Energy Commission and other agencies. He worked with the CIA in some capacity as well, but any activities are wholly classified as of 2015.Berkner worked with Dallas community leaders to establish the Graduate Research Center of the Southwest (later renamed the Southwest Center for Advanced Studies, which would eventually become The University of Texas at Dallas).He wrote more than 100 papers and several books, including Rockets and Satellites (1958), Science in Space (1961), and The Scientific Age (1964).
In 1961, Berkner was president of the Institute of Radio Engineers.

David Allen Hamburg (October 1, 1925 – April 21, 2019) was an American psychiatrist. He served as president of the Carnegie Corporation of New York from 1982 to 1997. He also served as the President of the Institute of Medicine, National Academy of Sciences and president of the American Association for the Advancement of Science. He had also been a member of the National Academy of Sciences since 1998. He was also a member of the American Academy of Arts and Sciences and the American Philosophical Society. He had previously been chair of the department of psychiatry at Stanford. His wife, Beatrix Hamburg, followed a similarly successful career path. Their daughter, Margaret Hamburg, is a physician who has followed their footsteps into public service becoming Commissioner of the Food and Drug Administration in 2009. His son, Eric Hamburg, is an author, attorney and film producer in Los Angeles.
Hamburg was born in Evansville, Indiana. He was awarded the Public Welfare Medal of the National Academy of Sciences in 1998, its most prestigious award, and the Presidential Medal of Freedom in 1996. In 2007 he and his wife received the Rhoda and Bernard Sarnat International Award in Mental Health from the Institute of Medicine for their long careers in medicine and public service. He died in Washington, D.C., on April 21, 2019 from ischemic colitis at the age of 93.

Alexander H. Leighton (July 17, 1908 – August 11, 2007) was a sociologist and psychiatrist of dual citizenship (United States, by birth, and Canada, from 1975). He is best known for his work on the Stirling County (Canada) Study and his contributions to the field of psychiatric epidemiology. Leighton died at the age of 99 at his home in Digby, Nova Scotia.

Jane Marion Oppenheimer (1911–1996) was an American embryologist and historian of science.

Manuel Sandoval Vallarta (11 February 1899 – 18 April 1977) was a Mexican physicist. He was a Physics professor at both MIT and the Institute of Physics at the National Autonomous University of Mexico (UNAM).

Loren R. Graham (born June 29, 1933, in Hymera, Indiana) is an American historian of science, particularly science in Russia.

Joseph Irwin Miller (May 26, 1909 – August 16, 2004) was an American industrialist, patron of modern architecture, and lay leader in the Christian ecumenical movement and civil rights. He was instrumental in the rise of the Cummins Corporation and in giving his home town (Columbus, Indiana) international stature with its modern architecture buildings.
