23 February 2015 will mark the 110th birthday of Rotary International.  Our 1.2 million-member organization started with the vision of one man—Paul P. Harris. The Chicago attorney formed one of the world’s first service organizations, the Rotary Club of Chicago, on 23 February 1905 as a place where professionals with diverse backgrounds could exchange ideas and form meaningful, lifelong friendships. Rotary’s name came from the group’s early practice of rotating meetings among the offices of each member.

 

“WHATEVER ROTARY MAY MEAN TO US, TO THE WORLD IT WILL BE KNOWN BY THE RESULTS IT ACHIEVES.”

—PAUL P. HARRIS

Paul P. Harris, an attorney, wanted to create a professional group with the same friendly spirit he felt in the small towns of his youth. On 23 February 1905, Harris, Gustavus Loehr, Silvester Schiele, and Hiram Shorey gathered at Loehr’s office in Room 711 of the Unity Building in downtown Chicago. This was the first Rotary club meeting. They decided to call the new club “Rotary” after the practice of rotating meeting locations.

Within five years clubs had formed across the country, from San Francisco to New York.
