Pavel Pavlovich von Winkler (1866 - c. 1937) - a famous Russian herbologist, genealogist, historian of German origin. In 1892-1894, Winkler published his work under the title - "Russian Heraldry." In it, along with general theoretical issues, he planned to give a description and image of all the noble emblems included in the general coat of arms of the Russian Empire. The book remained incomplete, but its possible scale is indicated by the fact that the text of the three issues that saw the light was accompanied by 903 drawings of Russian emblems.
