 Kis 's surviving matrices were first acquired by Stempel , and are now held in the collection of the <unk> ( Museum of Printing ) , Darmstadt . They were earlier often called the Janson designs , after the Dutch printer Anton Janson , based in Leipzig , who it was once believed might have created them , and Linotype 's revival of the same designs in a less condensed form accordingly is named Janson . Kis 's identity as the maker of the typefaces was rediscovered by comparison with type from Hungarian archive sources ( including an autobiography ) on which his name was identified .
