Can one property help highlight the changes in Naperville, Illinois in the last century? I ran into this news item first published May 30, 1946 in The Naperville Sun:

The Moser Fuel and Supply company has just completed the first new house to be built in Naperville since the outbreak of the war in 1941. This “No. 1” house, as it is referred to by Moser employees, is at 417 S. Sleight St., and is a little dream in brick veneer with chocolate-color mortar. Ten other Moser houses are going up around No. 1, eight of which are in the 400 block of south Sleight Street and two on South Wright Street.

According to multiple real estate websites, the current house on the property was constructed in 2004 and is worth over $1 million. Here is a June 2019 Google Street View image of the block, including the newer home on the property:

Several patterns worth noting:

-Naperville was a different place after World War Two: much smaller in population, lots of farms and agriculture around.

-Harold Moser and his firm ended up building thousands of units in Naperville. Moser Highlands, one of his first subdivisions, is just south of this location. He and his wife are honored in a statue along the Naperville Riverwalk:

-There are lots of teardown homes in Naperville, particularly near the downtown. As Naperville expanded in population and its status grew, some of the older suburban homes built decades earlier gave way to larger structures. I studied patterns in some of these new homes in a 2021 article.

In other words, this was not just one home constructed by a resident who owned a local business; it was part of larger changes to come in a suburb that became large and wealthy.
