Herman Pietersz (1584) A native of Haarlem. M. Havard places him as one of the founders of the potter’s industry, but not much is known of his work.
Thomes Jansz (1590) An Englishman.
Gerrit Hermansz (1614) A very few of the earliest specimens of Delft are supposed to be by him.
Cornelis Cornelisz (1628) Certain specimens marked with a ” C ” are attributed to him.
Abraham de Kooge (1632) A stranger. This great master has already been referred to. His plaques and dishes in blue may be considered as some of the finest early specimens of Delft. The paste is rather thick and the specimens, as a result, rather heavy, but the colouring and the glaze are very fine. His work was never signed, but the date is given in a small cartouche with the head of a cherub above.
Pieter Hieronimus Van Kessel (1634) Not much is known of his work, but he is supposed to be the founder of “The Metal Pot,” and certain specimens signed with the letter ” P ” are attributed to him.
Lambrecht Ghisbrechts (1640) A stranger. He is supposed to have produced models of cocks, ducks, etc., of a brilliant colouring and signed ” L G.”
Isaack Junius (1640) Two examples exist in blue, representing the tomb of William the Silent, and signed with Junius’ name in full and the date 1657.
Aelbrecht Cornelis de Keizer (1642) A stranger, and one of the great men. His name has already been referred to in conjunction with that of Abraham de Kooge. De Keizer’s work is amongst the best of the earlier potters. Its charm is due to its extreme thinness and lightness. De Keizer is also famous as the first to introduce the Chinese and Japanese style of modelling and decoration. In this he excelled, and this talent was handed down to his sons-in-law the Pynackers. His signature was a combined “A K.”
Ghisbrecht Lambrechtse Kruyk (1645) He may have been the founder of the celebrated pottery “Alpha,” for he handed it over to his nephew van Eenhoorn in 1674. Some specimens, of a rather pale colour, with his monogram of ” G K ” in blue, have a distinction peculiarly their own and are easily recognized.
Samuel van Berenvelt (1648) A stranger, supposed to be the founder of “The Double Jug” ; but we cannot attribute anything to his hand, for specimens with the mark of the factory ” D K ” or ” D S K ” give us no clue to the maker.
