Given the question: Found the following article online, use it to answer the question: What is the last name of the person whose tenure in in Mühlhausen was from 1706 to 1708?  Bach is known as a prolific composer of cantatas. When he assumed the position as Thomaskantor (director of church music) in Leipzig in 1723, he began the project to write church cantatas for the occasions of the liturgical year – Sundays and feast days – a project that he pursued for three years.Bach was appointed organist and chamber musician in Weimar at the court of the co-reigning dukes in Saxe-Weimar, Wilhelm Ernst and his nephew Ernst August on 25 June 1708.
