    Thanks for researching and writing this article. I thought it was very interesting.

    Do you know how Carl Heinrich Knopf (1839-1875) died at age 35?

    Unfortunately the cause of his death is not listed in his death certificate. Btw, my Part 2 of the Knopf Dynasty will be featured in the August issue.

  2. Hello friends,

    My publication is out: "Sartory and the case of spurious bows" it is the complete story of Sartory's court battle in the US, and includes a lot of new important statistical information regarding his working methods etc.

    I tried to download the photo here, but no luck.

    Here is a link to a post on FB 

     (3) Les Archetiers - Bow Makers : Dear all, my new publication "Sartory and the case of spurious bows" is out | Facebook


  3. Interesting thread. Btw, according to Sartory, his assistants did the rough work. He would finish all the bows himself. 

    If you are interested, you can read my article from February Strad issue 2019 about Sartory and his legal battles against trademark infringement in America.  Although Monsieur Sartory refrained from disclosing the names of his workmen/assistants in his deposition, we do know that prior to WWI, Sartory hired Jules Fetique in 1902, who stayed as his assistant until 1934. 

  4. It looks to me like a typical 2nd generation Knopf family bow. C.W. Knopf produced four sons who carried on his craft: Christian Wilhelm Jr. (1799-1835), Karl Wilhelm (1803-1860), Christian Friedrich Wilhelm I (1808-1874) and Christian Friedrich Wilhelm II (1815-1897). I'm posting two examples below by Knopf family members:  one of the sons of C.W. Knopf (C.W. Jr. or C.F.W. I) and Karl Moritz Knopf:







  5. Just came across this very interesting thread. This is no doubt a very nice example by Leman. The name of the instrument is "Izida", c.1908. Leman studied with Ernest Andre Salzard in Moscow (Arnold, Ludwig Otto and Arkhusen), later moved to Saint Petersburg. He was also a writer and editor and a professional billiards player. He wrote many books on violin making and violin acoustics. Admirers called him the "Messiah of the Violin".  He declared himself the "Russian Stradivari".  Initially that title was bestowed upon Ivan Batov in 1829 when he won the big silver medal at the 1829 Russian Exhibition (Manufacturing Expo). Leman stands out as one of the most important researchers in violin acoustics of the late 19th and early 20th centuries.  Leman traveled to Italy and other countries in Western Europe to study the works of great masters.

    Do you mean the German immigrant who worked in Ny until 1939?

    i know he made instruments, but he also surely imported them, and best to clarify which you have.

    Fine Bowmaker, too.

    Yes Henry R. Knopf.  Preferably c.1919 and after. He modeled them on the Alard and Messiah Strad. Of course we all love his bows too.

    Hey Gennady,


    Not anymore. I sold it about 6 years ago. Very Germanic work, and branded on the side of the heel, under the end button, on the bass bar, on the neck block...

    Hi Duane, any pics leftover?

    No, but I knew Frank 1975 - 1977, at one time he used to work for Weisshaar as well and helped me make my first bow which I ended up making too whippy. It would have been far worse without his help. Great guy and very open if you liked bows and bowmaking. Hans had a nice bow collection and he would come in to study them.

    That is amazing to know. Thank you for sharing!!

    Has your data been published?

    This subject is in progress, and will be part of a bigger story.

  10. I came across this very interesting discussion. Perhaps we could revive the subject? 

    Collection numbers are often a mystery.

    But with regards to certain numbers on the Nurnberger bows here, the #1896 represents the year of manufacture. As it stated so in this 19th century Wurlitzer catalog. And the other brand No.5858 is a Wurlitzer number.

    One should consider that the matter of August Moritz Knopf is challenged between German experts. I have no clue how an AM Knopf should look like,  but the certified examples seem to look so different to each other that (for me) it would be hard to decide about anything based on these as reference. And BTW, I don't see much affinities between your (rather nice) bow and the OP.

    We talked these further up in this thread before, in case you missed it. But I'm supposing you are the same person anyway?

    If one studies the bows of the Knopf workshop from C.W. Knopf to Henry R. Knopf and their disciples, one begins to understand their characteristics and evolution from early 1800's to 20th century.

    Thank you very much for your comments on this bow. It was in the case of a violin that I purchased, and it is a wonderful player. Of the bows that I play with it is second only to my Voirin, and it has become my daily player. I am interested in any additional information that you might have about it, and would be happy to post additional picture views, if you would like.

    Hello everyone and  GeorgeH,

    Hope you are all well.  I came across this thread and was reminded...about a bow (August Moritz Knopf) I thought I would share. It's a A.M. Knopf bow that was certified by H.C. Schmidt in Dresden. Which seems to be very similar to yours. Also the marks on both sides just below the leather looks like perhaps the  jig was too tight when it was re-haired long ago, or perhaps it had some kind of clamp there. It's unfortunate. But, there are those who do more harm than good when it comes to re-hairs.

    Anyway, I've been busy writing in the last two years, about Sartory and his legal battles against trademark infringement in the February 2019 issue of STRAD. Napoleonic Bows June 2020 issue of STRAD and currently Carlo Bisiach and his US connections November 2020 issue STRAD magazine. 

    All the Best,

  13. wow, I had no idea you guys were discussing my list.

    I created that list using an Apple app which does not exist anymore. So I'm not able to update it. But working on redoing my site, so at some point it will get done. And I am busy these days writing new research about other things. 

    One of my recent articles was regarding E. Sartory and his court battles against Trademark infringement in Feb. 2019 STRAD issue.

    I have an upcoming article regarding Napoleonic Bows followed by part discussing  proliferation of the Tourte bow. And finishing up new research on Nikolai KITTEL.


    BTW, my friend Clive Greensmith  is  also using bows by Jean-Luc Tauziede and Sylvain Bigot (when he is not playing the Tourte). I believe Robert DeMain also has a KITTEL.

    Dear Gennady,

    I refereed to this data about Kittel here https://maestronet.com/forum/index.php?/topic/337981-to-kittel-or-not-to-kittel/&do=findComment&comment=755941

    Do you have new documentary sources, or are you referring to his indentures too? Also with Maryyanenko, I knew the data you mentioned. Do you by chance know who he learnt from?

    I would very much enjoy reading your new research, so please tell me when and where it is/will be available!




    Yes I have uncovered a lot of new information regarding Nikolai Kittel and his circle of friends.

    Vitacheck mentions Maryanenko, but does not specify where or with whom he learned the craft.
