Actually, I remember the SE corner of Addison & Central having a Sinclair gas station and car wash. Mayflower, later Kohl's, and eventually Dominick's, was on the northeast corner, the northwest corner, where the professional building now sits, had a cream terra cotta building with a Rexall Drug store right on the corner. On Central, you can see a Chinese restaurant, but the original Catania's Jolly Inn extended around the back of the building and had doors both on Addison and Central. When the hospital bought up the corner lot from the Catania building, they moved out to Irving & Neenah and founded the banquet hall that eventually became a Polish buffet. As part of the deal, the hospital also built a new "Catania Building" on Central, just north of the alley north of Addison, but that was also torn down a few years ago and is now an empty lot. The southwest corner of Addison and Central had a three story building, yellow brick, stores on the first floor and apartments above. I really don't remember what was in the stores, but I am pretty sure it was still there in the early 1970's. Across the street, where the garage now sits, was a row of nice, oversized Chicago brick bungalows. I remember the hospital originally being "Northwest Hospital," and it was just a one story building that was mainly an emergency hospital. If you look at the front of the hospital, the first floor part of the building that is now covered with white marble was about the extent of the original hospital. I believe it had about six rooms. I was pretty familiar with it due to frequent, all night long nosebleeds. The western end of the hospital, where the clinic and parking lot now sit, was also a three story building, stores on the first floor and apartments above. This was a red brick building. I remember a television and radio store being there on the corner, possibly Shipley TV?
I'd like to suggest a good source of photos on this area that you might not be familiar with: www.trolleybuses.net Click on the Chicago dot on the map, and most of the pictures of the Addison-Central area will be under the "Marmon-Herrington" group of pictures.
