I also remember Wieboldts. Our local store was the one at Harlem Irving, but my grandmother often went to the one at Harlem and Lake so she could also visit the Marshall Field & Co. store across the street. I often sat out in the car with my grandfather, listening to The Texaco Opera of the Air, with Milton Cross narrating.
My parents, however, preferred the Harlem Irving location, and the one thing I cannot forget about Wieboldts is the pound cake they used to sell in their food department, which was located in a little annex to the main store, right around the "bend" in the old mall. I have never found anything like it since.
A little sidenote about the Wieboldt family...the Wieboldts were very generous with charities, and donated a lot of money to various universities and charitible institutions in the area. For years, I have always found cemeteries interesting, and often searched for the grave of William A. Wieboldt who founded the company. I expected to find an impressive grave like the monuments of Marshall Field in Graceland, or the Carsons of Carson Pirie Scott in Rosehill, but was really taken aback when I found William Wieboldts grave, marked with just a modest monument, along the fence at Wunders Cemetery on Clark Street. When you visit the Chicago Historical Society website, a letter he wrote back home to Germany as a young man is featured describing the Chicago Fire. Both William and his wife Anna lived to ripe old ages, both living to around 100 years old.

In reference to Steinberg Baum, there were two locations on the northwest side of Chicago that I remember. The first was on the 3400 block of N. Cicero Avenue, where the US Post Office is now located, and they also had a location on Grand Avenue and 72nd Court, across the street from Goldblatt's, where the Caputo's is now located.
