Sidney Michael Dancoff (September 27, 1913 in Philadelphia – August 15, 1951 in Urbana, Illinois) was an American theoretical physicist best known for the Tamm–Dancoff approximation method and for nearly developing a renormalization method for solving quantum electrodynamics (QED).
Nicolás Rolando Gabaldón (February 23, 1927 – June 6, 1951) was an early surfer who is credited by surfing experts with being California's first documented surfer of African-American and Latino descent at a time when many beaches were segregated and opportunities for minorities more limited than today. Despite being an amateur recreational surfer rather than a professional competitive surfer, he is widely considered a role model for his part in the history of surfing and African American history in the areas of Santa Monica and California.Gabaldón was born February 23, 1927, in Los Angeles, California. His mother was Black and his father was Latino. Very little is known of his childhood. He lived most of his life in Santa Monica, California and was one of 50 black students at Santa Monica High School during the 1940s. Gabaldón taught himself how to surf at a 200-foot roped off stretch of demarcated beach which was part of Santa Monica State Beach. This area of beachfront was informally referred to by names such as "Ink Well Beach", "Negro Beach", and other more derogatory names. In 1924, after the forced closure of black owned and operated Bruce's Beach and due to de facto segregation, that portion of beachfront near Bay Street and Ocean Boulevard became the only place in Southern California that racial minorities were freely allowed to use without harassment or violence. The area remains popular with African American Angelenos up through present day.
Raymond Martinez Fernandez (December 17, 1914 – March 8, 1951) and Martha Jule Beck (May 6, 1920 – March 8, 1951) were an American serial killer couple. They were convicted of one murder, are known to have committed two more, and were suspected of having killed up to twenty victims during a spree between 1947 and 1949.
After their arrest and trial for serial murder in 1949, Fernandez and Beck became known as the Lonely Hearts Killers for meeting their unsuspecting victims through personal ads, posted in newspaper lonely hearts columns. A number of films and television shows are based on this case.
François Hussenot (22 March 1912 – 16 May 1951) was a French engineer, credited with the invention of one of the early forms of the flight data recorder.
He attended the École polytechnique from 1930 to 1932. After graduation, he attended two other schools: the Ecole Militaire d'Application de l'Aéronautique in Versailles, where he obtained his pilot license, and the Ecole Supérieure d'Aéronautique (better known as Supaéro), which he graduated in 1935 with a degree in aeronautical engineering.
His career began at the Centre d'Essais de Matériels Aériens (CEMA) of Villacoublay, an aircraft test center, in 1935. In July of that year, he married Yvonne. In 1936, he was sent to Saint-Raphaël, in southern France, to take part in the testing of heavy seaplanes. In 1941, he moved to the Centre d'Essais en Vol de Marignane, where he made his early attempts at constructing a flight data recorder. Unlike modern recorders, Hussenot's early models had the particularity of storing the information not on a magnetic band, but on an eight meter long by 88 mm wide photographic film, scrolling in front of a thin spot of light deviated by a mirror to represent the data. The initials HB stood for Hussenot and Beaudouin, the name of an early associate who helped Hussenot in developing the device during World War II. Those flight recorders were also known as "Hussenographs".
In July 1945, Hussenot was appointed as an engineer at the Brétigny-sur-Orge flight test center (Centre d'Essais en Vol de Brétigny-sur-Orge) as the director of the Methods and Try-Outs service (Service des Méthodes et Essais). In 1946, with Maurice Cambois and Charles Cabaret, he created the Ecole du Personnel Navigant (E.P.N.) school, which later became the EPNER (Ecole du Personnel Navigant d'Essais et de Réception). As of today, the EPNER is one of only six test pilot schools in the world, together with the Empire Test Pilots' School, the United States Air Force Test Pilot School and the United States Naval Test Pilot School, the National Test Pilot School, and the Indian Air Force Test Pilots School.
In 1947 Hussenot founded the SFIM (Société Française des Instruments de Mesure) with his associate Marcel Ramolfo, to market his flight data recorder. The SFIM had a successful story of its own, selling many successful data recording devices, before diversifying. The company is today part of the Safran group.
In 1948, Hussenot became professor at SUPAERO. In the same year, he was appointed Chevalier de la Légion d’Honneur, and was awarded the Médaille de l'Aéronautique (Medal of Aeronautics) in recognition for his services.
François Hussenot died in 1951, in a plane crash between Marignane and Mont-de-Marsan.
Jacques Cariou (23 September 1870 – 7 October 1951) was a French show jumping champion. Cariou participated at the 1912 Summer Olympics held in Stockholm, where he won a gold medal in the individual jumping, a silver medal in team jumping with the horse Mignon, and a bronze medal in individual three-day eventing with the horse Cocotte.
Reinhold Trautmann (16 January 1883 – 4 October 1951) was a German Slavist. He is best known for his translations of the works of Slavic literature, such as his 1931 translation of the Primary Chronicle into German. He also conducted research of Slavic languages spoken in Germany.
Leopold Andrian, actually Leopold Freiherr Ferdinand von Andrian zu Werburg (May 9, 1875 in Berlin − November 19, 1951 in Fribourg) was an Austrian author, dramatist and diplomat.
Bernhard Weiss (30 July 1880 – 29 July 1951) was a German lawyer and Vice President of the Berlin police during the Weimar Republic. A member of the liberal Deutsche Demokratische Partei, Weiss was known as a key player in the political tensions during the Weimar Republic and a staunch defender of parliamentary democracy against extremists on the left and right.
Su Muy Key (November 4, 1929 – November 10, 1951) was a Mexican vedette, film actress and dancer of Chinese descent. She was one of the first Burlesque performers in México. She was nicknamed "Muñequita China" ("Chinese Doll").
Carl Ferdinand Eyring (August 30, 1889 – January 3, 1951) was an American acoustical physicist. He was the dean of the College of Arts and Sciences at Brigham Young University (BYU) for 26 years and was also the vice president of the Acoustical Society of America from 1950 until his death in 1951.
