The 24-inch gauge and the common gavel: an entered apprentice mason's perspective on the medical profession.

By developing their character and philosophy, Freemasons have sought to improve their communities and society through the arts, sciences, humanities, and other fields and have made important contributions. Freemason physicians such as Alexander Fleming, Charles Mayo, William Withering, and Edward Jenner have left a medical legacy that still impacts our daily lives. The foundation of Freemasonry beliefs is taught through two primary symbols, known as the working tools of an entered apprentice mason: the 24-inch gauge and common gavel. The meaning behind each of the working tools has parallels to the education and professional standards embodied within the medical profession.
