Early Telephone Pioneer

JOSEPH J. O'CONNELL

TELEPHONE PIONEER, INVENTOR
& ENGINEER MADE SUBSTANTIAL
CONTRIBUTIONS TO THE EARLY
DAYS OF THE TELEPHONE
INDUSTRY IN CHICAGO.
MR. O'CONNELL RETIRED FROM
ILLINOIS BELL IN 1930 AFTER 52
YEARS OF SERVICE. HE LIVED ON
THIS SITE FROM THE EARLY 1880'S
UNTIL HIS DEATH IN 1939 AT AGE 98.
THIS PLAQUE IS GRATEFULLY
DEDICATED TO HIS MEMORY
BY ILLINOIS BELL."

He held numerous patents for his innovations, which significantly advanced telephone technology. Some of his notable inventions include:

  • Circuit breaker and coin return: These were essential for the functionality of early telephone systems, particularly for public payphones.
  • "Invisible wire" (Multiplexing): This groundbreaking invention allowed more than one telephone conversation to occur on the same wire, dramatically increasing the capacity and efficiency of telephone networks. This was a precursor to modern multiplexing technologies.
  • Telephone exchange apparatuses, electric circuits, and switchboard functions: He developed various improvements to the central office equipment that connected telephone calls, making the process more efficient and reliable.
  • Party-line system: While sometimes associated with eavesdropping, the party-line system was initially a vital innovation that allowed multiple users to share a single telephone line, especially in rural areas, making telephone service more accessible.
  • Coin collectors for telephone toll lines: His work helped establish the infrastructure for pay-per-call services.

Seeing this house in the Old Town Triangle district of Chicago and reading the plaque reminded me of this old family photo of my grandfather and the crew he worked with at Illinois Bell in the early 1930s.

So often I wish I could go back and ask questions and learn more about the lives of the people in my family who have passed on.

Love the old phone gif! Reading about this guy reminded me I has that old family photo that says Illinois Bell on the back. Wish I knew more details. Grandpa went on to become a crane operator.

My grandkids think the idea of putting money into a payphone slot to be able to make a phone call is hilarious. They can't begin to imagine the days before cell phones.

Remembering and telling the stories is important.

That guy was an innovator, and he must have made a fortune off of those patents. Then to live to 98 years old, talk about a long life, and he achieved so many impressive things in his years working with the telephone company. There wouldn't have been the old public pay phones if he hadn't come up with the idea!

And party lines! I remember that we had a party line when I was very small up until the time that my father wanted to use the phone and a neighbor was talking and wouldn't yield to him. I think we had a private line installed the next day!

We also remember the time when we used to go and pay money to make a phone call and use the phone for two minutes. Those were the old days, they are memorable.
