7 septembre 1872 (Douai) - 28 décembre 1963 (Courbevoie)

The manufacture of ceramic in Boulogne-sur-Mer (Pas-de-Calais, northern France) is attested from 1754.

In 1775 Gaudy makes sandstone in the Dutch style and gray earth pieces often decorated in blue.

Louis Marie Verlingue creates a pottery factory in 1772. He makes earthenware in the style of Rouen and faience tiles until 1798 when Verlingue goes Desvres (20 kilometers from Boulogne). In 1801 Duval father and son resumed the pottery where they make dishes, boxes and inkwells. Until 1830.

In 1862 Victor Evrard has a small factory. In 1873 Bonard makes ceramic..

In 1903 Jules Verlingue creates his pottery (centre de La Madeleine) with Mr. Lagarde. Some pieces are marked LV.

In December 1913 the fire of some buildings of the Jules Verlingue factory to Boulogne-sur-Mer puts this company in big trouble and Jules Verlingue must become partner with his banker Henri Delcourt. In July 1914 Jules Verlingue acquires the HB Quimper company, but he is called shortly after and entrusts the company to Henri Delcourt. The war and the death of Guy De La Hubaudière, owner of the pottery of Quimper delay the sale, which will be effective in 1917, when Jules Verlingue leaves Boulogne. The banker Henri Delcourt continues to help Jules Verlingue in realizing his projects. A company called Manufacture de la Grande Maison HB, J. Verlingue and Co. with a capital of 90 000 Francs. is created. Henry makes his brother Leon lawyer in Versailles enter the capital.

In 1918 Jules Verlingue sells his partner Henri Delcourt its shares in the company of Boulogne-sur-Mer and, in parallel, Henri Delcourt sells Julius Verlingue its shares in that of Quimper. Delcourt stays alone at the head of this pottery, but he continues to use the models created by J Verlingue. Many exchanges persist between the two factories ... Do not forget that his brother Leon is shareholder of that of Quimper. His statuettes and Breton sceneries in this period are in the style of the creations of Quimper.

He raises the signature Liane that, as Odetta in 1922 in Quimper, is related to the river that runs nearby. Henri Delcourt appeals to artists such as Jacques Adnet, Louis Sue or Sibylle May who make his production available to the Paris market and in particular the designs studios of the department stores as Primavera (Au Printemps) and La Maîtrise (Galeries Lafayette). He makes creations, becoming one of the biggest names in Art Deco style both in the field of ceramic as of porcelain that he develops from the 20s. At sixty, he sells the pottery in 1932 but this one closes in 1935.
