Allen-Bradley's Original Clock
ŠTed Schaar 2009

Nine of the images on this page showcase a sight not seen in Milwaukee for decades: the original Allen-Bradley (now Rockwell Automation) four-sided clock, completed in 1950.  On November 19 of that year, The Milwaukee Sentinel reported it was "credited with being the largest four-faced clock in the United States" and had "faces measuring 21 feet in diameter." 

"Timing is by IMB" the article continued in a typo that might indicate how new and unknown the Information Age powerhouse then was. The company is referred to correctly as "International Business Machines Corp."2 earlier in the story.  Exactly what motivated Harry Bradley to fund this giant tower clock is unknown.  He was Allen-Bradley's leader after older brother Lynde died in 1942.  The clock lasted just 12 years and then was converted to a temperature gauge that displays degrees in Fahrenheit to this day. 

Its replacement—affectionately called the Polish Moon—was unveiled on Halloween, 1962, and is the largest four-sided clock in the world, with faces just over 40 feet in diameter.3  According to Milwaukee historian John Gurda in his book about the Bradleys, Harry intended the current timekeeper to be, “…the village clock for Allen-Bradley’s home neighborhood.”4   Architect Fitzhugh Scott, Jr., who designed its look said, “Harry wanted a clock that Allen-Bradley’s workers could read from their houses.”5   There is no mention of the Polish Moon's predecessor, but it's reasonable to think Harry's objectives for the 1950 clock were similar. 

The octagonal shape of both timekeepers reflects Allen-Bradley's trademark, first registered in 1923.6  My interest began in 1982 when I became a writer for Allen-Bradley and discovered to my amazement that no one knew why the octagon was chosen to be the company's logo. 

Researching that mystery took me through various archives and acquainted me with these evocative photographs of the 1950 clock.  Each appeared on the cover of Allen-Bradley's monthly employee magazine, originally called Gossip and later renamed Contact.  

I have also included a 1958 Gossip cover photo that shows the southeastern corner of the Allen-Bradley complex and the neon logo that appeared just outside the double bay windows of the apartment Harry and Margaret "Peg" Bradley occupied at the plant.  A black and white daylight view of the same corner is also presented.7   It came from a book published by the company titled The Allen-Bradley Story, copyrighted 1965, the year of Harry's death.
