Süss

The German mechanic and designer Ferdinand Süss (Nándor S.) founded the Suss Nandor fele Praecizios Mechanikai Intezet in Budapest in 1900 for the production of fine mechanics and optics, which also included the production of geodetic instruments.

In 1934, the company was renamed Magyar Optikai Müvek (MOM). After the war, the MOM company also operated in the electrical engineering field; in 1963, it took over the geodetic production of the Meopta plant in Prague. Especially its gyrotheodolites or radio rangefinders were  known in our country. MOM ceased to exist in 1990.

Of interest is that VZÚ Prague used two repetition theodolites of the Süss company (with a horizontal circle diameter of 30 cm and 21 cm)  during the first-order triangulation in Moravia in 1923.
