De Harmonie is a Dutch publishing company best known today as the publisher of the Harry Potter series of books since the 1990s, though their largest success didn't come until the 2000s and since 14 February 2008 they are located on Herengracht in Amsterdam. The company was founded in 1972 by Jaco Groot and his wife Elisabeth, and publishes 30-40 new titles per year, mostly visually-oriented material such as illustrated children's books, comics and art books, but also poetry and prose. Choices whom to publish are still made by the founders, though from an attic room on the Singel they have come a long way since Harry Potter. More information...
