Only three references to Alfred Baer, photographer, were found.
There were many references to an Alfred Baer, physician, but no connection could be made to the photographer.
There is also an Alfred Baer listed in the 1940 US census, the Find-a-Grave website and the 1905 Wisconsin state census but no occupation is included anywhere and this one was born in 1899 making him basically too young for the cabinet card era.
Timeline 1870 US census at 7 living with Gattiker family 1880 Baer worked at William Lathrop studio, La Crosse, WI, (from narrative about Lathrop) 1907 Red Wing, MN, city directory as photographer
No guess on the age of these cabinet cards, although the designs do indicate 1890 or after. If further information turns up it will be added here.
