On the building at 1300 N. Milwaukee Avenue in Wicker Park reads in ornate lettering "P. Christensen."
Built in 1887, the building was designed by Christian O. Hansen. The original owner was P. Christensen. I couldn't find out what the P stood for, as not much is known about him. There were a number of P. Christensen's living in Chicago at the time and I wasn't sure which one owned this building. No records indicate that he ever actually lived here. At any rate, his name survives over 125 years later. Interestingly, the real-estate listing from 1887 shows his spelling as "Cristensen". The epigraph appears to have been spelled this way, but possibly corrected to insert an "h" between the C and R.
In 1901, George Remus had a pharmacy at this location, formerly 952 Milwaukee Avenue. Below is a newspaper account of vandalism at his property by a group of women Dowie supporters, claiming that pharmacists were evil.
The building is a contributing factor of the designation of the Milwaukee Avenue District in Wicker Park as a Chicago Landmark.
