(*27.12.1882 †2.02.1959 Den Haag)
First a link to the wonderful (german-language) site of Ralph Binnewirtz.
Which has two pictures and some interesting information about Alexander Rueb.
In the article Alexander Rueb (dutch) there is some more information about him.
Dr. Alexander Rueb was one of the founders of the Fide in 1924 and he was the first president of FIDE in 1925.
Dr. Rueb served as president of Fide for 25 years, from 1924 to 1949.
He was a lawyer of profession, an amateur chessplayer and wrote books on endgame studies.
He was also a big collector of chessbooks.
The chesscollection of the Alexander Rueb Foundation is now in the library of the University of Amsterdam.
Alexander Rueb also was once chairman of the oldest chessclub of the Netherlands in The Hague DD (Discendo Discimus),
where he bought a building which is called the NSG (Nationaal SchaakGebouw), translated as: National Chess Building.
The name EBUR of the Arves-magazine is an anagram of Rueb as you might have guessed.

Rueb also played correspondence chess, and along with Max Euwe and Alexander Alekhine,
promoted the idea of a world correspondence championship in the 1930's,
which did not come to fruition until after World War 2.
Rueb was also awarded the International Arbiter title by FIDE in 1951.
