According to the American Heritage Dictionary of Idioms, "'Hanging out one's shingle' is an American idiom dating back to the early 1800s, when lawyers, doctors and other businesses used shingles for signboards." As one etymologist explains, " 'Hang out a shingle' now means to open an independent practice... and advertise that. It's a metaphor for all of the activities that might bring in clients or patients. [A] member of any profession may 'hang out a shingle': it could be done by a security consultant or an insurance agent just as well as by an attorney or physician, as long as the person is opening a solo practice or business.
