Recently, the City of O'Fallon has been considering the possibility of asking the voters, perhaps next year, to eliminate the elected positions of City Clerk and Treasurer and transfer their duties to the City's professional staff. The two positions date back to 1905, when O'Fallon converted from a village to a city form of government. We thought it would be interesting to look back at what the City Clerk and Treasurer did back then. Here are pages from O'Fallon's 1905 code of ordinances listing the duties of each.

Back then, unlike today, the City Clerk and Treasurer, as well as the Mayor, ran for 2-year terms. What were they paid? The City Clerk made $100 per year plus 25 cents for each license issued or transferred. The Treasurer made $50 per year. Both were required to post bonds. The Clerk's bond was $1500. The Treasurer's was "fixed at a sum not less than double the amount of the estimated tax receipts and special assessments for the current year and the estimated annual receipts of the city from licenses and other sources."

The first City Clerk was William R. Lawrence. He had been the Village Clerk from 1903 to 1905. He served as City Clerk from 1905 to 1907, when he was defeated by Rudolph Kampmeyer for a second term. He died on May 24, 1907, not long after the election, at the age of 28.

The first City Treasurer was Joseph Taylor. He was elected unopposed in 1905 and served until 1907, when he decided not to run for re-election. He later served as City Mayor from 1909 to 1911.

The next Pub Table Historian is Thursday night, August 13, 2026, from 6 to 7 p.m. at Gears Bar and Cafe inside Bike Surgeon at 201 E. State St. in Downtown O'Fallon. With school starting up again, this month's topic is the early history of schools in the O'Fallon area. We promise - no pop quizzes!

As always, food and drinks are available for purchase, and all ages are welcome.

*** PROGRAMMING CHANGE. Next month, Pub Table Historian will be on the 3rd Thursday, September 17. We'll switch back to the usual 2nd Thursday the following month. Same time - 6 p.m.

Pub Table Historian is a free monthly history talk sponsored by the O'Fallon Historical Society. It is usually held on the second Thursday of each month (with some exceptions) from 6 pm to 7pm and covers different topics relating to the history of O'Fallon and the surrounding area. It's an informal evening, and questions and input are welcome and encouraged. Watch this page for future dates and topics.

Whether you've lived here all your life or just arrived yesterday or even today, this is your town, this is our town—and everyone is equally welcome to come and join us for a bit of O'History!

Check out the new page we created for The Caboose - Downtown O'Fallon IL! Over time, we'll add more to it, but we thought it was about time the iconic Caboose in Downtown had its own page.

Here are photos of the historical displays and activities around the Grange log cabin during O'Fallon's America 250th celebration on July 3 at Community Park. We were happy to partner with the Looking Glass Prairie Chapter NSDAR, as well as historian and historical interpreter, Ray Brundege, to make it happen. While the heat kept the crowds relatively slim, we still had about 500 visit the cabin area and 164 visit inside the cabin during the morning and afternoon. Thank you to everyone who helped make it a very worthwhile addition to the festivities!

On Saturday, July 18, 2026, from 10 a.m. until noon, we're having an Open House at the Caboose on West First Street to belatedly celebrate the completion of its recent repainting, the addition of new exterior signs, and a general refreshing of the interior. We've also added the names of recent donors to the Caboose Fund on an inside plaque. While supplies last, we'll have complimentary "Caboose" cake from Wood Bakery and punch. The Vine Street Market Peach Festival is also that morning (from 8 a.m. to noon). So, you can visit the market and the Caboose in the same trip. We hope you'll stop by and visit us!

The next Pub Table Historian is Thursday night, July 16, 2026, from 6 to 7 p.m. at Gears Bar and Cafe inside Bike Surgeon at 201 E. State St. in Downtown O'Fallon. With O'Fallon's America 250th celebration over, we thought it would be a good time to talk about what O'Fallon did 50 years ago for the Bicentennial in 1976. For those of you who were here back then, we encourage you to come and share your memories, too!
