Knoll & Pregizer

Knoll and Pregizer
The Robin Deutsch Collection

Jewelry by Knoll & Pregizer. Pforzheim, Germany.

Founded in 1887 by Theodor Eberhard Friedrich Knoll and Friedrich Pregizer.
Friedrich Pregizer left the company in 1907.

Registered in 1887 (Theodor Fahrner book page 68) misspelled.
They also made watches signed KAPE registered in 1938 and also signed Lotos.

455 Zugang 1992-53 Nr. 372 Post WWII Archive Records that show they were registered as a business from 1948-1973. however I have found a patent for a watch crystal in 1975. This, along with the 1887 date of registration as a company from the Theodor Fahrner book and patent info confirms that Knoll & Pregizer were in business from 1887 thru 1975.

Researching Google Books I found a listing from the 1970s of Der Deutsch-Amerikaner von heute:Deutsch-Amerikanisches Adressbuch fur due-by Stefan Deubel Page 383:

By what I have seen of the gold pieces I believe these were made while the company was winding down in the 1960s-1970s. Nothing is as grand or as extraordinary as their hey day up until the late 30s and the start of World War II.

I have been collecting this exquisite jewelry for about ten years now, unfortunately compared to the size of some of my other collections this one is much smaller as it is usually hard to find. Each acquisition of a piece of KP has been a joy to acquire. In my collector's eye, they are the Cartier of German costume jewelers. This is just a small portion to give you an idea of the quality of jewelry made by this amazing company. Sometimes the KP punch is so small that you might not even know you have a piece. I have had pieces for a couple of years before I found the mark. Sometimes I will buy a piece of it missing stones knowing I might never be able to repair it just to have it in my collection. Each piece is handcrafted from sterling silver, using the finest paste and imitation glass stones mimicking platinum,diamonds, rubies, sapphires and emeralds. Sometimes they will use semi-precious stone colors such as amethyst and onyx. The pieces are constructed exactly as a piece of fine jewelry would be, and I am sure the same jewelers working on real jewelry also made these exquisite imitations. My saddest loss was not being able to buy a Cartier copy of an Art Deco Egyptian Revival scarab brooch they made but I will never forget that piece. You never forget the ones that get away...and sadly several have.

For years it remained one of those jewelry mystery marks that remained unsolved to us American collectors. I had noticed the company name listed in the Theodor Fahrner Jewelry Book not as KP, but as Knoll & Preziger (misspelled) and that piqued my interest. I tried researching the name every way possible and all I would get on occasion would be watch auctions on eBay. One day as I was researching I could not believe what I found. An eBay auction from a seller in Uruguay of all places who was selling a 1953 Atlanta Post catalogue containing German jewelry and accessory companies. The seller listed the names of the companies in the auction and photos of many pages. There it was. A photo of jewelry with the KP Trademark and the company name. In all my years of research this was probably one of my happiest and proudest moments. To be able to connect and confirm all of the information together.

This 1953 catalogue page confirms without a doubt the attribution of jewelry marked KP Sterling Germany (or KP 925 or 935) to Knoll & Pregizer of Pforzheim, Germany.

What is fascinating is in their long history they made Victorian/Art Nouveau, the garland style jewelry popular in English Edwardian and French Belle Epoque and the MOST extraordinary (and my favorite) breathtaking Art Deco Jewelry. Because of the 1953 catalogue page you can see the change in their style of jewelry after WWII. Amazingly, I have discovered several patents dated from 1908 thru 1975 registered in Germany, France and the UK. Many of their watches were made in 14K gold. Recently I have discovered they also made jewelry in 14K and 9ct gold for export to England.

Pforzheim, Germany had hundreds of jewelry manufacturers on par with Providence, RI here in the US. I have many pieces of jewelry just marked Sterling Germany, but **UNLESS THE PIECE IS MARKED KP, IT WAS NOT MADE BY KNOLL & PREGIZER**. This is important to note as it would be irresponsible and unethical to attribute jewelry to a company without their known trademark.

Per his great-great grandson Thomas Wolfgang Maguire on 8-12-09 the family tree is: Theodor Eberhard Friedrich Knoll ( 1851-1928) (Great-Great-Grandfather) ---- Theodor Knoll(Great-Grandfather) (1881-1961)----- Margarete Nestlen nee Knoll (1914-1984) ---- Margrit W. Maguire nee Nestlen (1943) --- Thomas Wolfgang Maguire (1981) His mother Margrit is the granddaughter of Theodor Knoll.

VERY EXCITING NEWS PER GREAT-GRANDSON THOMAS WOLFGANG MAGUIRE ON 9-10-09:
"The History of Knoll & Pregizer according to the Archives in Pforzheim and translated from German."

"The Knoll Family originates from Schwäbisch Gmünd, there they had a small shop inside their home to make Jewelry for the Areas Jewelry Stores.

After Theodor Eberhard Friedrich Knoll learned to be Goldsmith in the Home Business of His Father and learned at a Technical School did he go to The Military. After he left the Military in 1877 did he take up a position as a Apprentice in a Fine Pforzheim Business, after two years he made himself independent and founded a small business in Pforzheim. In 1882 did he take into the company The Merchant and Traveling Imitation Jeweler Friedrich Pregizer. The Company now was run under the Name of Knoll & Pregizer.

The offer was extended to the production of Imitation products using Fine Pour Technique. In the future the company was able to begin thanks to a little competitive pressure to increase their sales steady and even train their own apprentices. There was establishing or further branches and others in Nagold. In 1907 Pregizer resigned from the business.

After the two eldest sons, Carl and Theodor of merchants had completed training in Pforzheim stores, They picked up their father as an employee and left them after 1914, the sole managing director. From the effects of World War I. The production activity (could be maintained only in very restriction. The Nagold branches had to be closed.) Recovering the company after the war, again due to high demand, was relatively quickly.

Carl Knoll, the eldest son and later on the city council had received since 1906 with the departure of Frederick Pregizer transferred the commercial management of the business. He married about 1908 Margarete nee Nestlen with which he had three children, Ilse (born 10.12.1908), Marianne and Walter (both born on 27.5.1911) had. The latter subsequently took over the lead. Erich Keller, son of Ilse Knoll first marriage, was transferred in 1957 by the participation in the business.

Both Life Stories which are steepened the above information is taken to give a great insight into the families and Company history, especially from the Pforzheim Foundation 1879 to 1958. In addition, the city archives has in its files Commercial Papers (Knoll & Pregizer, jewelry and watches factory, manufacture of watches and jewelry, Walter Knoll; Friedenstr 62; Goethe Strasse 16."

All of the pieces are from my collection except where noted. Some photographs are from the sellers I bought the pieces from.

Many thanks to my dear friend and colleague Dr. Kristin Rheinwald in Germany who so patiently helped me translate and navigate these German archives. She has been invaluable to me and a wonderful friend.

I would also like to thank the very gracious keeper of the Knoll Family History, Thomas Wolfgang Maguire, great-great grandson and great-grandson of both TEF Knoll & T. Knoll for being so generous sharing his time and family history and wonderful photographs. He contacted me after reading my article at www.illusionjewels.com.

Cathy's site is www.imageevent.com/bluboi It's quite long and breaks apart into two bracelets of which I have not figured out how to do and probably never will. Look how exquisite the pendant is, and the entire necklace chain and top part of the pendant is made out of baguettes. This is the best piece of KP I have and will treasure not just for it's beauty, but for the fact that it came from such a wonderful friend. c.1930

It actually matches the mark on my KP bracelet that is in #9. It is the initials EG on either side of the Jewish star. Someone once floated the idea that the jeweler, because he was Jewish and working in Germany during the 1930s, had to include that in his stamp, the same way he probably would have had to wear a Jewish star around the sleeve on his arm. The necklace and bracelet and the little penguin pin are the only pieces I own with this makers mark with the Jewish star.I have seen another two over the years on the internet.

There's also another indecipherable mark that could have been for export to another European country. You can see close up even after so many years how wonderful the millegrain mounting is with brilliant, masterfully bead set stones just like real diamonds would be. All of this was hand done.	enlarge 69KB, 1024x216 10 KP Sterling Deco Paste Bracelet c. 1930.

The unfoiled round green pastes are all prong set, the round pastes are bead set and the baguettes are channel set. Marked KP Sterling Germany. This is the sellers pic, one day I will have to reshoot it. The same one with ruby colored stones was sold at Doyle's Auction House about 2000-2001 and can also be seen in Harrice Simons Miller Third Edition of her Price Guide to Costume Jewelry Page 95. I've since had all the baguettes replaced and the foil removed from the clear stones as well as replacing some of the round pastes that were missing. It's an astoundingly beautiful piece.

I soaked it in a bath of vinegar and salt removing all the foil. You would never know this was not platinum and diamonds. I love the mixture of the geometric cuts of stones.

From the Collection of Christia Schutt. www.grandmasjewelrybox.com This piece came to me through my friend Christia and shows how imparting knowledge to each other in the world of research is so important. Knoll & Pregizer is known as a costume jewelry company. Their ads even say "Imitation Jewels". But in a Post WWII German record I found (#70) listing KP as "Goldschmuck"-Fine Jewelers (meaning they worked in at least the minimum of 8K gold as well as making imitation jewelry in sterling.) Until this piece was discovered, the only gold jewelry they were known for was their watches. They may have decided to go into the fine jewelry business at the end of their long career of making imitations. Since...

Robin, Thanks so much for your extensive research. You've saved me from who knows how many hours, days, or years of fishing for info on these marks. I acquired a duette brooch just last Thursday and here it is Sunday and I already have my answer! I am so grateful. I'd love to chat with you about it.
