Early years

Johann Kapsch founded a precision mechanics workshop in Vienna’s Neubau district in 1892. From the beginning, the postal and telegraph authorities were amongst the most important customers. The devices and services of Kapsch proved themselves and the small workshop grew over 20 years into a sizeable operation. In 1912, Kapsch had a factory built on premises which it owned in the Meidling district of Vienna. The First World War initially had no effect on the company’s growth; telecommunications equipment was needed by the railways and postal services as well as the army.

Hughes Printing Telegraph


The telegraph consisted of a piano-style keyboard with letters, numbers and punctuation marks. In contrast to the Morse telegraph, a directly readable ‘clear text’ could be printed on paper strips. The telegraph was used by the postal and telegraph authorities; it was developed by David Edward Hughes in 1855.

New Factory Building

1913, Photograph

A state-of-the-art factory building was constructed in Vienna’s Meidling district on the corner of Johann-Hofmann-Platz/Wittmayergasse, between 1912 and 1913. The company’s first factory on its own premises with large, bright rooms made efficient production possible. Ernst Epstein (1881-1938), who designed numerous residential and industrial buildings in Vienna during this time, was responsible for the architecture.

Articles of Association of Kapsch

1916, Draft from 1914, approved in 1916

In 1904, Johann Kapsch’s three sons founded the company Kapsch & Söhne together with their father. This officially announced the leap from the simple mechanic’s business into ‘industrial operations’. The prerequisites for a joint stock company are explained in the articles of association.

Portable Telegraph Relief Writer


The relief writer offered two advantages: first of all, all components were mounted on a panel, making the device easily transportable. Secondly, the writer left an embossment on the paper – which was especially advantageous for the military as it allowed information to be analyzed without a light source.

Share with a Value of 200 Crowns


After the beginning of the First World War, Kapsch supplied products almost exclusively to the army. While this allowed the company to significantly increase its sales, it became more and more dependent on the military, which paid its bills very lately, if at all. The expansion of its financial framework may have been one of the reasons why the company was converted to a joint stock company in June of 1916 and three bank directors joined the board of directors.
