Summary:
Erres; Den Haag, NL:
Radioproduction:
1923 -
History:
The name Erres was derived from the initials of R.S. Stokvis, of trading-company R.S. Stokvis & Zn in Rotterdam. This trading-company made technical products since the end of the nineteenth century.
Using the name Erres Radio, Stokvis started building and selling radios around 1923. An advertisement for the first radio, the one valve receiver Erres 1, appeared in the radio magazine "Radio-Wereld", that year. For the first series of radios Erres used parts made by different factories: Dutch N.S.F., the English Sterling factory, and later Dutch factories Van der Heem & Bloemsma and Philips. The K.W.S (1928), KY103 and KY104 (1929) were the first AC radios. Erres claimed to have made the first commercial Dutch AC radio with a built-in loudspeaker, the KY107.
In 1926, Van der Heem & Bloemsma is the most important radio maker for Erres. After the recession of 1929, Erres' results decrease and the influence of Philips increases. In 1930 Philips becomes an important share-holder, and the Erres continues to sell radios and televisions, most of them made by Van der Heem, with mainly Philips components. In the mid sixties Philips takes over Van der Heem.
