Earth, Wind & Fire once asked: “Do you remember the 21st night of September?” and it’s been stuck in our heads ever since.

Today, we dug through the UofL archives to find some Louisville moments in time from some 21st nights (and days) of September across the decades.

1922: Even back then, people were excited about history. This replica log cabin sat on the old Kentucky State Fair Grounds.

1927: A look down the 100 block of North 4th Street — that's where the Galt House is located now. '

1928: Here UofL's student newspaper UofL News announces the addition of night classes to the college's curriculum. The first four courses: Principles of Economics, English Literature, American History, and Directed and Supervised Study in Junior and Senior High Schools (what a mouthful).

UofL News lives on today as The Louisville Cardinal.

1931: The site of this bottling plant is now the main office for KFI, a local company that makes designer office furniture.

1944: Civilian clothes or WWII uniforms? This woman could have been manufacturing either at the Louisville Textile Company. Bonus: The site of this photo is now Hop Atomica + the Germantown Mill Lofts.

By 1948, Louisville Textiles Inc. was Kentucky's largest textile mill. | Photo UofL, ASC

1949: This photo was taken inside a shop on Market Street
— Check out the box of irradiated coffee in the lower left corner.

Oertel's was a Louisville beer staple that started in the current Whirling Tiger building. It closed in 1967.

1973: This is what the Belvedere looked like 50+ years ago. It'll probably look quite different 50 years from now.

This photo was taken just five months after the Belvedere opened. | Photo courtesy UofL, ASC
