It contributed a number of original type designs early in the 20th century,[1] some of which were designed by S. H. de Roos and Dick Dooijes.
In the 20th century, only two major typefoundries survived in the Netherlands. In Haarlem, the old typefoundry of Joh. Enschedé was their competitor. In order to divide the market, these firms kept a certain difference in type-height. Amsterdam: 66 + 1/24 point Didot, and Enschedé: 66 - 1/24 point Didot. Enough to prevent the combined use of their type.[citation needed]
Eventually, it became a division of Tetterode.[1] On October 1, 2000, Tetterode transferred the rights for all of its typefaces to Linotype.[1]
