- Around 1880, Eugene Dietzgen emigrated from Germany and became a sales distributor for Keuffel & Esser in New York. In 1885, he began to sell mathematical instruments on his own in Chicago. In 1893, his firm started manufacturing instruments under the name Eugene Dietzgen Company. In 1928, the business began importing these particular instruments to sell as the Prep product line for students. Model number 1084S was then priced at $4.70. By 1936, the set cost $5.45. In 1938, the handles on the pen and screwdriver were painted black and no longer were ridged. The patent referenced on the case is not known.
- The large dividers and bow dividers clearly were put into the set later to replace original pieces. Charvoz made sets of drawing instruments in West Germany in the second half of the 20th century. According to the donor, this set of drawing instruments was used by her husband, the electrical engineer Robert H. Wieler (1923–1993). He likely acquired the set around 1937 as a school student.
