Fritz (Friedrich) Seitz (12 June 1848, Günthersleben-Wechmar, Saxe-Coburg and Gotha – 22 May 1918) was a German Romantic Era composer.
Heinrich Bach was born at Wechmar, Germany, and is the father of the so-called Arnstädt Line.
Four branches of the Bach family were known at the beginning of the 16th century, and a Hans Bach of Wechmar is documented to have been alive in 1561, a village between Gotha and Arnstadt in Thuringia, who is believed to be the father of Veit Bach.
