C58 Two Kts aren't enough
Lodewijk Prins (27 January 1913, Amsterdam – 11 November 1999) was a Dutch chess player and referee of chess competitions. Prins was awarded the International Master title in 1950, and was made an International Arbiter in 1960. In 1982 FIDE made him an honorary Grandmaster.
At the beginning of World War II (1939–1940), he played in tournaments in Holland. In 1940, he won jointly with Salo Landau and Nicolaas Cortlever in Leeuwarden, took 2nd, behind Max Euwe, in Amsterdam (VVGA), and tied for 3rd-4th in Amsterdam (VAS, Hans Kmoch won). After the German invasion of the Netherlands in May 1940, his name did not appear in any tournament in the occupied Netherlands because of his Jewish origin. After the war, he took first place at Hoogovens Beverwijk in 1948 and at Madrid 1951 with 12.5/17, ahead of Herman Steiner, Herman Pilnik, and Ossip Bernstein. Prins qualified for the 1952 Interzonal and was Dutch Champion in 1965.
