Footnotes:
Christian Nissen, came from a family of opticians and in 1891 he established his own business in Helsinki handling eyeglasses, barometers, thermometers and binoculars and microscopes made by Ernest Leitz in Wetzlar.

The business was subsequently taken over by Nissen's brother in law, Gunner Vaenerberg, who quickly expanded the companies product range and turned the business into a flourishing enterprise.

With the introduction of the Leica 1 in 1925, the Nissen company was able to add a significant new product to its range. So successful was Helsinki agency that Ernst Leitz II dedicated this Leica No. 452 to Vaenerberg.
