Hans Albrecht Bethe (German pronunciation: [ˈhans ˈbeːtə] ; July 2, 1906 – March 6, 2005) was a German-American theoretical physicist who made major contributions to nuclear physics, astrophysics, quantum electrodynamics, and solid-state physics, and who won the 1967 Nobel Prize in Physics for his work on the theory of stellar nucleosynthesis. For most of his career, Bethe was a professor at Cornell University.During World War II, he was head of the Theoretical Division at the secret Los Alamos laboratory that developed the first atomic bombs. There he played a key role in calculating the critical mass of the weapons and developing the theory behind the implosion method used in both the Trinity test and the "Fat Man" weapon dropped on Nagasaki in August 1945.
After the war, Bethe also played an important role in the development of the hydrogen bomb, although he had originally joined the project with the hope of proving it could not be made. Bethe later campaigned with Albert Einstein and the Emergency Committee of Atomic Scientists against nuclear testing and the nuclear arms race. He helped persuade the Kennedy and Nixon administrations to sign, respectively, the 1963 Partial Nuclear Test Ban Treaty and 1972 Anti-Ballistic Missile Treaty (SALT I).
His scientific research never ceased and he was publishing papers well into his nineties, making him one of the few scientists to have published at least one major paper in his field during every decade of his career, which in Bethe's case spanned nearly seventy years. Freeman Dyson, once his doctoral student, called him the "supreme problem-solver of the 20th century".

American supercentenarians are citizens or residents of the United States who have attained or surpassed 110 years of age. As of January 2015, the Gerontology Research Group (GRG) had validated the longevity claims of 782 American supercentenarians. As of March 12, 2024, it lists the oldest living American-born person as Spanish emigrant Maria Branyas (born in San Francisco, California, on March 4, 1907), aged 117 years, 8 days. The oldest American resident is listed as Elizabeth Francis (born in Houston, Texas, on July 25, 1909), aged 114 years, 231 days. The longest-lived person ever from the United States is Sarah Knauss, of Hollywood, Luzerne County, Pennsylvania, who died on December 30, 1999, aged 119 years and 97 days.

Garner Ted Armstrong (February 9, 1930 – September 15, 2003) was an American evangelist and the son of Herbert W. Armstrong, founder of the Worldwide Church of God, at the time a Sabbatarian organization that taught observance of seventh-day Sabbath and annual Sabbath days based on Leviticus 23.
Armstrong initially became recognized when he succeeded his father as the voice of The World Tomorrow, the church's radio program that aired around the world. A television program of the same name followed, aired mostly in North America, eventually giving way to a Garner Ted Armstrong broadcast, a half-hour program that mixed news and biblical commentary. His polemical message was unlike that of most other religious broadcasters of his day.

Robert A. Trias (March 18, 1923 – July 11, 1989) was an American karate pioneer, founding the first karate school in the mainland United States and becoming one of the first known American black belts.

Juan Díaz de Garayo y Ruiz de Argandoña, also known as "The Sacamantecas" ("The fat extractor" in Spanish) (October 17, 1821 – May 11, 1881), was a Spanish serial killer active near Vitoria, Álava, who strangled five women and a 13-year-old girl, and attacked four other women during two different periods, 1870 to 1874 and 1878 to 1879. A lust-motivated serial killer, Garayo first killed prostitutes after hiring and sleeping with them consensually, but grew more disorganized and violent as time went on, attacking, raping and murdering women that he saw walking alone in the country. His last two victims, murdered in consecutive days, were also stabbed, and the second was disemboweled.
Garayo's persona and crimes were the subject of El Sacamantecas, an 1881 monograph written by Ricardo Becerro de Bengoa, who visited Garayo while he was in prison awaiting execution.
