Alberts Frères

[1] The company was founded by brothers Albert (1879–1941) and Willy Mullens (1880–1952); they were the main filmmakers and exhibitors in the Netherlands in the first two decades of the twentieth century.

Willy and Albert's father, Albertus Abraham Mullens (30 July 1847 Hoorn – 1890), alias "A. Alber(t)", and a German by the name of Ernst Ahrens Basch (1838-1908) had founded a theater company, Koninklijk Nederlandsch Cagliostro-Théâtre Alber & Basch, specializing in "mysterious and pseudo-scientific spectacles".

Christina took her sons to Paris, where they saw Auguste and Louis Lumière's films in the Salon Indien du Grand Café.

[7][8] Willy Mullens later became a well-known producer of documentary films; his Holland Neutraal: Leger en Vlootfilm (1917) received a royal premiere, in the presence of Queen Wilhelmina and Prince Hendrik.

[9] During World War I the company was hired by Kaiser Wilhelm's Dutch legate to film German children celebrating Queen Wilhelmina's birthday in 1919.
