The founder of the later Senzora, Antonie Johannes Schoemaker, embarks on the adventure on 1 May 1876 and takes over the grocery store from widow J. A. Spijker on the corner of Stromarkt-Papenstraat in Deventer.

Antonie Johannes Schoemaker


Even in the early days, Schoemaker turned out not to be a standard grocer. The switch from wholesaler to soap manufacturer and coffee roasting company is therefore no great surprise to his environment. He settles in a small factory at the Bruynsteeg (formerly Diefsteeg), also in Deventer.


The company is growing and the possibilities for expanding the building on the Bruynsteeg soon prove to be too limited. The two sons of Schoemaker have their eyes on a site at the Raamstraat 4. The new factory is soon a fact.

A.J. Schoemaker en Zonen changes its name to Senzora (Schoemaker and sons Raamstraat). The name originated from a competition between the Schoemaker brothers and sisters.


Even in the first construction drawings of the factory at the Raamstraat, space has been reserved for peppermint production. In the annual report of the Chamber of Commerce, Senzora is now officially listed as a soap powder and peppermint factory.

Sodaproductie 1936


The Schoemakers think it is time to expand the production range again. Senzora is the first in the Netherlands to start producing crystal soda.


Senzora is the first in the Netherlands to conduct in-house research into phosphate-free detergents. And with success! At the end of 1971, the TNO published positive reports on the composition and washing power of the detergent Tricel developed by Senzora, which is biodegradable and completely phosphate-free.

The policy in the eighties and nineties is characterized by countless necessary innovations, and Senzora grows into a dynamic, flexible, but also internationally oriented company. As a logical consequence of these developments, the new washing powder factory at the Noorwegenstraat is put into operation in 1996.


In 2001 Senzora obtains the predicate: "By Appointment to the Court of the Netherlands". This means that we distinguish ourselves through quality, solidity and continuity within our business operations
