Het Spectrum
Het Spectrum is a Dutch publishing house.
It publishes books, under its own name and two other trade marks: Winkler Prins and Prisma. Since September 1999, Het Spectrum is a business unit within PCM Algemene Boeken.
Het Spectrum was established in 1935 by book sellers P.H. Bogaard and A.H. Bloemsma. From its humble beginnings in a room above a bakery in de Biltstraat in Utrecht the publishing developed to become one of the largest in the Netherlands. At Het Spectrum work about 50 employees.
Het Spectrum started as a progressive-Catholic publisher that aspired to supply good reading materials to the masses. Hence it published many pocket books. After World War II, this formula continued as Prisma Pockets. Among the pocket books were translated classics for the modest price of 1,25 guilder. The Prisma dictionaries were also part of this line.
Dutch authors published through Het Spectrum include Godfried Bomans, Han van Bree, Hubrecht Duijker, L. T. F. Gamut (a pseudonym of five authors together), Ben Tiggelaar, and Janwillem van de Wetering. International authors include Dorothy Parker, Dr. Phil, Peter Singer, Edgar Wallace, and P. G. Wodehouse.
