Kohn, Siegfried, Diamond Cutter, Gold and Silversmith, and Practical Working Optician, 59 Lambton Quay, Wellington. Bankers, National Bank of New Zealand. London agents, Messrs. Bradey and Cohn, 36 Basinghall Street, E.C. This business was established nearly forty years ago in Christchurch, and for some years the Wellington establishment was conducted as a branch, eventually being taken over by the present proprietor on his own account. Mr. Kohn's premises are centrally situated and well appointed. The building, which is of iron, containing upwards of 2500 square feet of floorage space, consists of shop, sight-testing room, and a large workshop at the back. The shop has a magnificent plate glass front, displaying a wealth of precious stones, jewellery, watches, plate-ware etc., which are dazzling in their brilliance, especially when illuminated by the electric light. The interior, fitted up with splendid show cases, each containing choice articles of great value, is lighted from a handsome dome, on which are emblazoned the coats of arms of successive governors of New Zealand who have bestowed their patronage on this prominent establishment. The optical department, which is elaborately furnished and lighted from above, is supplied with a vast collection of lenses numbering upwards of 15,000, and complete apparatus for accurately testing the sight, Mr. Kohn having devoted himself specially to this part of his profession, Further behind are situated the large workshops, which include a complete plant of machinery of the latest design. The rolling mill for silver and other metal plates is reputed to be the largest in the Colony: the sliding die box press will deliver a blow equal to seven tons falling ten feet; there are also wire rollers and hammers for striking blows with steel dies, of which there are three hundred cut in hard steel, many of them having cost large sums to engrave; and a grinding machine for lenses. Mr. Kohn, who is a native of Prussia, served his apprenticeship with the celebrated diamond setters, Messrs. Lionhardt and Fiegel, of Berlin, and after several years subsequent experience, passed his examination at the Master Goldsmith's Institute, coming to New Zealand, per ship “Somersetshire” in 1873. As an exhibitor, he has taken prizes for jewellery at Paris, Melbourne, Sydney, and at all New Zealand Exhibitions. For many years Mr. Kohn has held contracts for the supply of passes, medals and watches to the Colonial Government — the members' gold passes for New Zealand railways, the medals granted by the Defence Department, and the guards' watches used for the last twenty years on the railways. Agricultural medals and large trophy shields in abundance have also been produced at these works. Mr. Kohn has a large staff of experts employed in the business. His brother in London acts as buyer, and makes regular shipments of clocks, watches, plate, optical goods, and jewellery of the best quality and of the latest and most fashionable styles, by mail steamers.
