Albert Hermann Daur was a German painter and graphic artist.
His training began in 1885 at the Schieder Drawing School in Basel. In 1886, Hermann Daur began his studies at the Karlsruhe School of Arts and Crafts under Franz Sales Meyer and Max Laeuger. In 1888, he became an assistant at the Furtwangen School of Watchmaking. From 1891 to 1902, Daur studied at the Grand Ducal Art School in Karlsruhe under Ernst Schurth, Robert Poetzelberger and Carlos Grethe.
After attending the painting class under Leopold von Kalckreuth and studying in the graphics class under Walter Conz, he completed his studies in 1902 as a master student of Hans Thoma. During his semester breaks, he often stayed in the Dachau painters' colony with Adolf Hölzel. From 1895 onwards, he spent time every year in the fishing village of Duhnen near Cuxhaven, where he met his future wife, Margarete Boldt. From 1906, Daur was a freelance artist in Ötlingen in southern Baden, which is now part of Weil am Rhein. In 1909, he undertook a study trip to the Swiss Engadine.
