In the last decade of the 19th century (1897 is named most often), Gerolamo Ceresa began to work as a subcontractor for the pipe factory of Ferdinando Rossi in Barasso, where extensive building projects had led to bottlenecks in production. In this first period the bowls were made in Cassano Magnago while the mouth pieces were prepared and polished in a very small workshop in Cavaria. Even so there was already a water driven generator. The Ceresa sons Pietro, Enrico and Luigi grew up joining the family business one after another. Although Pietro and Enrico were sent to the front, the production during World War I could be continued. In 1919 the Ceresas acquired an area of land on Via Visconti in Cassano Magnago where a new factory was built. All business activities were united in the new rooms. Since the complete factory was operated electrically, the firm received the new name Gerolamo Ceresa - Fabbrica elettrica pipe. "Electric pipe factory" sounds a bit amusing today, but at that time it was certainly the proud expression of modernity! To bring forward the company furthermore on the European markets, Enrico went to Saint-Claude in 1923 for some years to study the fabrication procedures of the French manufacturers. Returned to Italy in 1926, he extensively restructured and modernised the firm. A new name was coined: Fabbrica Pipe Cassano. The order fabrication for Rossi was continued, but from now on also own pipes under the brand name Cassano were offered with increasing success. The Ceresas were among the very first who strove to sell Italian made pipes with a quality above the abundantly produced industry ware. Since 1970 Carlo Ceresa, a son of Enrico, is heading the Fabbrica Pipe di Carlo Ceresa & C. as it is currently named. In 2004 there were eight employees working in the production. Sales are running so well that Ceresa today must make use of wherewith they themselves once began: subcontractors! The principal customer are still the USA where Cassano pipes are regarded as an estimable Italian series pipe, featuring very good characteristics already for less than 100 dollars.
