Around 1868 Emil Oscar Richter (*1841-†1905) establishes a clockmaker's workshop at Poststrasse 15 in Chemnitz. In 1874 he invents his dotting pen, and his drop bow compass in 1875. His revolutionary flat system of drawing instruments was developed in 1892. Richter's first illustrated catalogue comes out in 1897 (see timeline below). In 1875 Richter and business partner Hugo Lucas Müller establish E.O. Richter & Co. From 1883 to 1894 Richter's business partner is Carl Hermann Bonitz (*1840-†1895). From 1898 to 1900 Richter's head clerk is Emil Arno Steidtmann, who along with instrument-maker Emil Otto Roitzsch both leave Richter in 1900 to establish their own drawing instrument company Steidtmann & Roitzsch. After Richter's death his widow Auguste Richter became the company's proprietor. Richter's son Hans Richter, who until then held the post of head clerk (Prokurist) became the proprietor in 1908.

Richter's monopoly of the flat pattern production ended when the compass joint patent ran out in 1907.

Richter proportional compass

Richter proportional compass retailed by Johannes Philippus Bladergroen (*1855-†1922) in Amsterdam. His father Jacobus Pieter Bladergroen [1] (*1825-†1903) was the proprietor of Stefanus Mostert & Zonen printers in Rotterdam. Johannes Philippus starts his business in stationary around 1900 [2], and in 1906 forms a company with his brother Wouter Jacobus [3] (*1853-†1920). Bladergroen's stationary shop was located at Raadhuisstraat 30-32 Amsterdam in a building designed by architects H.P. Berlage and H. Bonda, built in around 1900 [4]. Bladergroen's stationary shop in the Raadhuisstraat continued until the early 1970s.

Richter double drop bow compass

This double drop bow is used for drawing 2 small concentric circles at the same time. Somewhat of an oddity, the Richter double drop bow is not listed in any known catalogue. Neither could we find a Richter patent for a double drop bow. The Richter logo on the case illustrated on the left indicates a production date prior to WW2.  

 

The first recorded double drop bow is in an unillustrated advertisement in 1849 by Carl Geiger Mechanikus and Optikus in Stuttgart Germany (Preis-Verzeichnis Carl Geiger, 'Doppelter Nullenzirkel', Gewerbeblatt aus Württemberg No. 22, 27-10-1849, p. 379). DEPATISnet has no patent listed for a Richter double drop bow, however we find a 'Grenzsteinzirkel' DRP 51307 patented by Gartz in 1889, a 'Grenzsteinzirkel' DRP 338756 patented by August Staufermann in 1921, and 2 patents by Erich Linnhoff for a double drop bow, patents 1214416A and 1214416B, dated 1966.

Richter (Wichmann 1061) dotter for straight lines 

This dotter was retailed by Gebr. Wichmann in Berlin, a retailer of drawing and surveying instruments that still exists today. The company's founder was Emil Wichmann who in 1873 opens a shop in drawing supplies in Karlstrasse 14 in Berlin. Renamed Gebr. Wichmann when Emil's brother Gustav joins the company in 1876.
