Johannes (Johann) Zick (January 10, 1702 – March 4, 1762) was a German painter of frescoes in southern Germany and active during the Baroque period. He was the father of painter Januarius Zick and considered to be an important master of the Late Baroque.
Johannes Zick was born in 1702 in Lachen, part of the territory of the Prince-Abbot of Kempten in the Unterallgäu in modern-day Bavaria, where he started his career as a blacksmith in his father's workshop. From 1721 to 1724, he was apprenticed to the Konstanz court painter Jacob Carl Stauder. They both painted the frescoes on the ceiling of the church Mariahilf in Munich.
Zick moved with his family to Munich in 1728 where he was appointed court painter to Prince Bishop Duke Johann Theodor of Bavaria. Johannes Zick's further development as a painter of frescoes was stimulated by the Asam brothers, who were active in Munich at the time.
Johannes Zick worked extensively in Upper Swabia between 1744 and 1749. Due to his employment in Upper Swabia, his family followed him there in 1746, living either in Schussenried or in Biberach an der Riß. In 1746, he painted the frescoes on the ceiling of the central nave in St. Martin's Church in Biberach an der Riß and, following his design, the other naves were reconstructed and painted with frescoes in 1747.
