Martinus Thomsen, referred to as Martinus, (11 August 1890 – 8 March 1981) was a Danish author, philosopher and mystic. Born into a poor family and with a limited education, Martinus claimed to have had a profound spiritual experience in March 1921. This experience, which he called "cosmic consciousness", would be the inspiration for the books he wrote later on which are collectively entitled The Third Testament. Some of his works have been translated into twenty languages, and while he is not well known internationally, his work remains popular in Denmark and to a lesser extent other parts of Scandinavia.

Walter Robert Wilhelm Grotrian (21 April 1890 in Aachen; † 3 March 1954 in Potsdam) was a German astronomer and astrophysicist.

Grotrian and Bengt Edlén from Sweden demonstrated that the two observed emission lines arise from iron atoms that have lost about half their 26 electrons.

Max Immelmann (21 September 1890 – 18 June 1916) PLM was the first German World War I flying ace.

He was the first aviator to receive the Pour le Mérite, colloquially known as the "Blue Max" in his honour, being awarded it at the same time as Oswald Boelcke. His name has become attached to a common flying tactic, the Immelmann turn, and remains a byword in aviation. He is credited with 15 aerial victories.
