Carl Friedrich Wilhelm Borgward (10 November 1890 in Altona, Hamburg – 28 July 1963 in Bremen) was a German engineer and designer and the creator of the Borgward group, based in Bremen.

Dino Galvani (born Candido Galvanoni; 27 October 1890 – 14 September 1960) was an Italian-British actor, who made his career in Britain on stage and radio and in films. He is remembered for his role in the popular BBC radio comedy series ITMA from 1941 to 1945. He was frequently seen on the West End stage, broadcast on radio and, later, television from 1927 to 1959, and made more than thirty films.

André-Louis Danjon (French: [ɑ̃dʁelwi dɑ̃ʒɔ̃]; 6 April 1890 – 21 April 1967) was a French astronomer born in Caen to Louis Dominique Danjon and Marie Justine Binet.Danjon devised a method to measure "earthshine" on the Moon using a telescope in which a prism split the Moon's image into two identical side-by-side images. By adjusting a diaphragm to dim one of the images until the sunlit portion had the same apparent brightness as the earthlit portion on the unadjusted image, he could quantify the diaphragm adjustment, and thus had a real measurement for the brightness of earthshine. He recorded the measurements using his method (now known as the Danjon scale, on which zero equates to a barely visible Moon) from 1925 until the 1950s.
Among his notable contributions to astronomy was the design of the impersonal (prismatic) astrolabe based on an earlier prismatic astrolabe developed by François Auguste Claude which is now known as the Danjon astrolabe, which led to an improvement in the accuracy of fundamental optical astrometry. An account of this instrument, and of the results of some early years of its operation, are given in Danjon's 1958 George Darwin Lecture to the Royal Astronomical Society.He also developed the "Danjon limit", a proposed measure of the minimum angular separation between the Sun and the Moon at which a lunar crescent is visible. However, this limit may not exist.
He was Director of the Observatory of Strasbourg from 1930 to 1945 and of the Paris Observatory from 1945 to 1963.Danjon was the President of the Société astronomique de France (SAF), the French astronomical society, during two periods: 1947–49 and 1962–64.He was awarded the Prix Jules Janssen of the Société astronomique de France in 1950, and the Gold Medal of the Royal Astronomical Society in 1958.
Danjon died in 1967 in Suresnes, Hauts-de-Seine.

Viktor Lutze (28 December 1890 – 2 May 1943) was a German Nazi Party functionary and the commander of the Sturmabteilung ("SA") who succeeded Ernst Röhm as Stabschef and Reichsleiter. After he died from injuries received in a car accident, Lutze was given an elaborate state funeral in Berlin on 7 May 1943.

Wilhelm Leuschner (15 June 1890, in Bayreuth, Bavaria – 29 September 1944, in Berlin-Plötzensee) was a trade unionist and Social Democratic politician. An early opponent of Nazism, he organized underground resistance in the labour movement. As a result of involvement with the assassination attempt on Hitler in 1944, Leuschner was executed.

Carlos Gardel (born Charles Romuald Gardès; 11 December 1890 – 24 June 1935) was a French-born Argentine singer, songwriter, composer and actor, and the most prominent figure in the history of tango. He was one of the most influential interpreters of world popular music in the first half of the 20th century. Gardel is the most famous popular tango singer of all time and is recognized throughout the world. Described variously as a baritone or tenor because of his wide vocal range, he was known for his rich voice and dramatic phrasing. Together with lyricist and long-time collaborator Alfredo Le Pera, Gardel wrote several classic tangos.
Gardel died in an airplane crash at the height of his career, becoming an archetypal tragic hero mourned throughout Latin America. For many, Gardel embodies the soul of the tango style. He is commonly referred to as "Carlitos", "El Zorzal" ("The Song thrush"), "The King of Tango", "El Mago" (The Wizard), "El Morocho del Abasto" (The Brunette boy from Abasto), and ironically "El Mudo" (The Mute).
In 1967, a controversial theory was published by Uruguayan writer Erasmo Silva Cabrera, asserting that Gardel was born in Tacuarembó, Uruguay. Other authors expanded upon this theory, and a museum to Gardel was established in Tacuarembó. But Gardel's friends and family all knew him as a French immigrant from Toulouse. Scholarly researchers analyzed the contradictory evidence, especially French birth and baptismal records, and confirmed his birthplace as Toulouse.

Rachele Guidi (Italian pronunciation: [raˈkɛːle ˈɡwiːdi]; 11 April 1890 – 30 October 1979), also known (particularly in Italy) as Donna Rachele (Italian for "Lady Rachel") and incorrectly as Rachele Mussolini in the English-speaking world, was the second wife of Italian dictator and fascist leader Benito Mussolini.
