Johann Leopold Mozart (1719-1787) born in Augsberg, Germany first published this didactic work in 1756, just after the birth of his son W. A. Mozart (1756-1789). The Treatise on the Fundamental Principals of Violin Playing appeared a few years after the Treatise on Playing Traverse Flute by J. J. Quantz (1752), and Ph. Em. Bach's The True Art of Playing Keyboard Instruments (1753). What caught my attention the most in Leopold's Violinschule, was that it was written more for the teacher than the student, and most importantly it can be used as a guide for "good artistic performance in general.'
