In 1925 Samuel Biedermann establishes, together with Gerard Weber, Radio-Apparaten en Onderdeelenfabriek "Weco" (also named "Weco Fabriek van Radio-Ontvangtoestellen en Onderdeelen"), Tolstraat 92-94, Amsterdam. Initially only accessories for radios are being made, like coils, switches and special resistors, but as from 1927 also radios are being constructed.
In January 1927 the company is transformed into NV Radiofabriek "Weco" with address De Ruyterkade 141-142, Amsterdam. As the business developed quite well, a larger building is purchased for offices, laboratory and production at the address Lijnbaansgracht 8-9-10, Amsterdam in February 1929.
In 1930 Weco makes the move to Belgium (Brussels), where the company Fonior manufactures the Weco models.
In 1936 Weco transforms its activities from radio production into the manufacturing of transformers. NV Radiofabriek "Weco" is liquidated in 1960. The transformer business is sold in 1971.
