Rotary International has 1.2 million members. How many people were at its first meeting?

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.

Rotary International is an international service organization whose stated purpose is to bring together business and professional leaders in order to provide humanitarian services, encourage high ethical standards in all vocations, and help build goodwill and peace in the world. It is a secular organization open to all people regardless of race, color, creed, religion, gender, or political preference. There are 34,282 clubs and over 1.2 million members worldwide. The members of Rotary Clubs are known as Rotarians. Members usually meet weekly for breakfast, lunch, or dinner, which is a social event as well as an opportunity to organize work on their service goals. Rotary's primary motto is "Service Above Self"; its secondary motto is "One profits most who serves best."
