I am writing the first book from the American point of view about 19th century rotunda panoramas. These were the biggest paintings in the world,50 x 400=20,000 square feet, housed in their own rotundas which were 16-sided polygons.Chicago in 1893 had 6 panorama companies and 6 panorama rotundas. William Wehner (4-27-1847/2-19-1928) of Chicago located his panorama studio in downtown Milwaukee. He produced 2 units of BATTLE OF ATLANTA, 2 units of BATTLE OF MISSION RIDGE, and 4 units of JERUSALEM ON THE DAY OF THE CRUCIFIXION. My great aunt, Mathilde Georgine Schley (1864-1941) was an artist/model in the Wehner studio. William's daughter was Ida Wehner (6-27-1873/2-4-1975). Her cousins were Charles Franklin of Fresno, Wanda Babcock of San Carlos, and Virgil William Kropf who married Mary Elizabeth Farrington on 10-18-1951. William died 6-24-1999. I have info to share.
