At the top of the building at 2056 N. Halsted Street in Lincoln Park reads C. SCHAUSS 1885.
Conrad Schauss was born in Germany in the early 1800's. He moved to Chicago in 1878 and he sold footwear ("boots and shoes" as listed in the 1885 directory) until this building went up in 1885, where he opened a saloon.
By 1900, he had died but his widow, Anna, remained at this residence. His son Adam had moved nearby to 1958 N. Halsted by this time, likely to be close to his mother. She died soon after.
When Adam died at age 71 in 1923, he was buried in Rosehill Cemetery (according to death records). It's likely Conrad is buried here, too, although a search online turns up no Schausses.
