Solomon Hanau - Wikipedia https://en.m.wikipedia.org/wiki/Solomon_Hanau 

Shlomo (Zalman) ben Yehuda Leib Katz was born in Hanau, Germany and lived in part in Frankfurt, Hamburg, Amsterdam, Berlin and Hanover. At the age of 21 he composed his first dikduk work, "Binyan Shlomo". Solomon Hanau was fiercely criticized by Jacob Emden, though Emden's father, Tzvi Ashkenazi, authored an approval letter to Solomon Hanau for his textual work. Recent study suggests that Shneur Zalman of Liadi followed many of Solomon's variations when composing his Chabad Nusach of Jewish prayer (Nusach Ari).
