Jacob Adolphus Holzer

Jacob Adolphus Holzer (1858–1938) was a Swiss-born designer, muralist, mosaicist,[1] interior designer, and sculptor who was associated with both John La Farge and Augustus Saint-Gaudens before he left to direct the mosaic workshops of Louis Comfort Tiffany,[2] where he was preceded by his friend from La Farge's studio, the German immigrant Joseph Lauber (1855—1948).

In Boston, he designed mosaics and three stained-glass windows for the Central Congregational Church, 67 Newbury Street (1893),[4] and perhaps the Frederick Ayer Mansion, Commonwealth Avenue (1899–1901).

He was the designer of the Tiffany dome at the Chicago Cultural Center, 78 East Washington Street (1897, Shepley, Rutan & Coolidge, architects).

[6][7] At Princeton, his mosaics of subjects from Homer fill the rear wall of Alexander Hall (William Appleton Potter, architect, 1895, now Richardson auditorium).

[8] In Troy, New York, his stained-glass east window and baptistry mosaics can be seen in St Paul's Church, remodeled under Tiffany's direction .
