I am writing the first spreadsheet 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.
I am the biographer of Mathilde Georgine Schley(1864-1941), dressmaker, owner of Schley Flats in Milwaukee, American Impressionist, telegrapher, essayist for the German-American press between the wars, diarist, author of DEUTSCHAMERIKA (1935) and FRITZ,PAT, JULES UND HANK (1940), collaborator with Pastor Wilhelm iwan (1871-1958 on his Die altlutherische Auswanderung um die Mitte des 19. Jahrhunderts (Breslau 1943), member Chicago No-Jury Society of Artists 1915-51 (exhibition record by Gene Meier), Wisconsin Painters & Sculptors 1900-2000 (exhibition record by Gene Meier), and artist-model in the panorama studio of William Wehner (1847-1928) featured in PANORAMA FOR A SMALL CITY by Gene Meier. Tante Tilde's legacy has taken me behind the Iron Curtain (1978) and to Perth, Western Australia (1989). Info to share
