Emmy and Harald Nielsen set up DIA-Nielsen on Kreuzstraße in Düren, Germany with the idea of offering all accessories that users of recording instruments need from one place. The company´s name DIA-Nielsen is based upon the term diagram and it will become the by-word of this burgeoning market in the future.
Our corporate strategy connected so well that there were no limits to growth and expansion. That´s why our company soon moved to its own business spaces into Industriestraße in the Lendersdorf borough of Düren.
Thanks to skyrocketing sales in marking system instruments, our company grew dynamically and we had to add onto our original building.
DIA-Nielsen creates fibre-tip pens for recording instruments, making it a pioneer in state-of-the-art diagram recording technology.
E. Nielsen K.G. is converted into DIA-Nielsen GmbH and we started working on facility II, our present headquarters in the Lendersdorf borough of Düren.
Emmy Nielsen, co-founder of our company, died in August of 1974.
At the onset of 1979, our company expanded its activities to the United States opening a production company in Cinnaminson, New Jersey.
1973, 1975, 1978, 1980
Our company´s excellent development allowed us to expand facility II even more.
The Einbeck-based Schleicher & Schuell takes over DIA-Nielsen, thus intensifying our already existing business relations with batra, manufacturers of papers for writing implements with headquarters in Traben-Trarbach, Germany.
DIA-Nielsen not only expands production for measuring technology, but also adds the production of disposable filters for life sciences to its programme.
Our development work in printing technology allows us to add ink jet products starting in the second quarter.
