Ackermann first accompanied field marshal Burkhard Christoph von Münnich on his travels and in battles. Born in Schwerin, he first entered the stage under a certain Stolle. In 1740 he entered the troupe of Johann Friedrich Schönemann in Lüneburg, where he first met his future wife Sophie Charlotte Bierreichel, who took the lead of the troupe in 1741 in Hamburg. The troupe dissolved in 1744 and they lived with relatives of Konrad in Mecklenburg. In 1747 he was hired in Danzig, later in St. Petersburg. In 1749 he and his wife visited Moscow where they marry. They left Russia in 1751 and founded the famous Ackermann troupe (Ackermann'sche Gesellschaft).
