Kolping

There is a building on East 88th Street between Lexington and Third Avenues on the north side of the street. The name over the door s the Kolping Society. I have seen young men go in and leave the building; they always seemed to be German speakers. It is in Yorkville, which used to be a heavily German neighborhood. But I couldn't find any information about what it was.
Until recently I was reading A History of Modern Germany by Dietrich Orlow. In the chapter on German unification, Orlow mentions a Roman Catholic priest, Father Adolph Kolping, "who began a series of shelters to provide temporary housing and support for traveling apprentices and journeymen," circa 1849. The Kolping Society has residences for men and women throughout the world.
