For more than 110 years, Rotary members have been addressing challenges around the world. Grassroots at the core, Rotary links 1.2 million members to form an organization of international scope. It started with the vision of one man — Paul Harris. The Chicago attorney formed the Rotary Club of Chicago on 23 February 1905, so professionals with diverse backgrounds could exchange ideas, form meaningful, lifelong friendships, and give back to their communities. Rotary’s name came from the group’s early practice of rotating meetings among the offices of its members.
