How did Friedrich Ludwig Jahn invent triple beam balance?

Friedrich Ludwig Jahn did not invent the triple beam balance; that credit goes to other inventors in the field of scientific measurement. Jahn is primarily known for his role in developing gymnastics and promoting physical education in Germany during the early 19th century. The triple beam balance, used for precise weighing, was developed in the late 19th century, long after Jahn's contributions to physical education and gymnastics.
