TOASTMASTER was founded and firstly organized by Ralph C. Smedley during his working time in YMCA (Young Men's Christian Association) in Bloomington, Illinois, United States. The purpose of the establishment was he saw a need for the men in the community to learn how to speak, conduct meetings, plan programs and work on committees, and he wanted to help them.

Back then, the term of TOASTMASTER was (and still obviously) widely known as a term referred to a person who gave toasts at banquets and other occasions. The first event of TOASTMASTER took place on March 24, 1905 leading to Smedley being offered positions in YMCA in San Jose, California.

The world needs leaders. Leaders head families, coach teams, run businesses and mentor others. These leaders must not only accomplish, they must communicate. By regularly giving speeches, gaining feedback, leading teams and guiding others to achieve their goals in a supportive atmosphere, leaders emerge from the Toastmasters program. Every Toastmasters journey begins with a single speech. During their journey, they learn to tell their stories. They listen and answer. They plan and lead. They give feedback—and accept it. Through our community of learners, they find their path to leadership.

• Conduct meetings
  Members learn how to plan and
  conduct meetings.

  Members present one- to twominute,
  impromptu speeches
  about assigned topics.

  Members present speeches based on
  projects from Toastmasters’ communication and

  as speech organization, vocal variety, language,
  gestures and persuasion.

  out speech strengths and offers suggestions for
  improvement.
