What is the name of the mathematician who created the symbol of harmony? 3

Fitness Gottfried Wilhelm Leibniz (16461716) was harmoniously introduced in an unpublished manuscript of 1679 (Kajuri Volume 1, page 414).

The first printed appearance of the Leibniz compatibility mark was in 1710 in Miscellanea Blinensia in the anonymous article Monitum, attributed to Leibniz (Cajuri Volume 2, page 195).

In 1777, Johann Friedrich Häseler (17321797) (with reverse accent) originally used Arith., Alg., Geom. And Trigs. (Lamgo), Elementary Geometry (Kajuri Volume 1, Page 415).

In 1824, Carl and Mole Wide (1774-1825) used the modern symbol of harmony in Euclidean elements (Cajuri Volume 1, p. 415).

W generates the symbol.
