A '''barber's pole''' is a type of [[Signage|sign]] used by [[barber]]s to signify the place or shop where they perform their craft. The trade sign is, by a tradition dating back to the [[Middle Ages]], a staff or [[:wikt:pole|pole]] with a [[helix]] of colored [[Stripe (pattern)|stripes]] (often red and white in many countries, but usually red, white and blue in Canada, Japan, the Philippines, South Korea, Vietnam, and the United States). The pole may be stationary or may rotate, often with the aid of an [[electric motor]].<ref name="dictionary">{{cite web |url=http://www.yourdictionary.com/barber-pole |title=Barber Pole |work=Webster's New World College Dictionary |location=Cleveland |publisher=Wiley Publishing |year=2010 |access-date=14 November 2010}}</ref><ref name="Smith">{{cite web|url=http://www.sensationalcolor.com/color-messages-meanings/color-meaning-symbolism-psychology/color-meaning-a-symbolism-why-barber-poles-are-red-and-white.html |last1=Smith |first1=Kate |title=Why Barber Poles are Red and White |work=Sensational Color |access-date=14 November 2010 |archive-url=https://web.archive.org/web/20101129123325/http://sensationalcolor.com/color-messages-meanings/color-meaning-symbolism-psychology/color-meaning-a-symbolism-why-barber-poles-are-red-and-white.html |archive-date=29 November 2010 |url-status=dead |df=dmy }}</ref> The consistent use of this advertising symbol can be seen as analogous to an [[apothecary]]'s [[show globe]], a [[tobacconist]]'s [[cigar store Indian]]<ref name=FLS>[https://news.google.com/newspapers?id=iOwQAAAAIBAJ&sjid=FYwDAAAAIBAJ&dq=cigar-store-indian&pg=5528%2C1776329 The Freelance Star (Sep 11, 1982) ''Cigar Store Indian was Early Advertising Sign''] Retrieved 2010 May 3</ref> and a [[pawn broker]]'s [[History of pawnbroking#Symbol|three gold balls]].<ref name"Andrews">{{cite book |url=https://books.google.com/books?id=uz6BAAAAMAAJ |title=At the Sign of the Barber's Pole: Studies in Hirsute History |first1=William |last1=Andrews |location=Cottingham, Yorkshire |page=1 |year=1904 |publisher=J.

A "barber's pole" with a helical stripe is a familiar sight, and is used as a secondary [[metaphor]] to describe objects in many other contexts. For example, if the shaft or tower of a [[lighthouse]] has been painted with a helical stripe as a [[daymark]], the lighthouse could be described as having been painted in "barber's pole" colors.

== Origin in barbering and surgery ==
[[File:BarberPole.jpg|thumb|Antique red and blue striped pole in Pottstown, Pennsylvania, United States]]
During the [[Middle Ages]], barbers performed [[surgery]] on customers, as well as [[tooth extraction]]s. The original pole had a [[brass]]en [[wash basin]] at the top (representing the vessel in which [[leech]]es were kept) and bottom (representing the basin that received the blood). The pole itself represents the staff that the patient gripped during the procedure to encourage blood flow,<ref>{{cite book |last=van Helmont|first=Jean Baptiste |title=Van Helmont's Workes, containing his ... Philosophy, Physick, Chirurgery, Anatomy |date=1644 |pages=504–516 |url=https://archive.org/details/b30324038/page/504/mode/2up}}</ref> and the twined pole [[Motif (visual arts)|motif]] is likely related to the [[Caduceus]], the staff of the Greek god of speed and commerce [[Hermes]], evidenced for example by early physician van Helmont's description of himself as ''"[[Franciscus Mercurius van Helmont|Francis Mercurius Van Helmont]], A Philosopher by that one in whom are all things, A Wandering [[Hermeticism|Hermite]]."''<ref>[https://archive.org/details/b30324038/page/n23/mode/2up Van Helmont's works: containing his most excellent philosophy, anatomy]</ref>

Under [[Pope Innocent II]] edicts were given forth (Council of Clermont 1130, of Rheims 1131, [[Second Council of the Lateran]] 1139) against medical practice by ecclesiastics.<ref>{{cite journal |last1=AMUNDSEN |first1=DARREL W. |title=Medieval Canon Law on Medical and Surgical Practice by the Clergy |journal=Bulletin of the History of Medicine |date=1978 |volume=52 |issue=1 |pages=22–44 |url=https://www.jstor.org/stable/44450442 |access-date=20 December 2024 |publisher=The Johns Hopkins University Press|jstor=44450442 |pmid=352450 }}</ref> At the [[Council of Tours 1163|Council of Tours in 1163]], the [[Roman Catholic]] clergy was banned from the practice of surgery.<ref>{{cite journal |first=Sir Arthur Salusbury |last=MacNalty |title=The Renaissance and its Influence on English Medicine, Surgery and Public Health |journal=[[British Medical Journal]] |date=1 December 1945 |place=London |publisher=[[British Medical Association]] |jstor=20364730 |pages=755–759 |volume=2 |issue=4430 |doi=10.1136/bmj.2.4430.755|pmid=20786422 |pmc=2060364 }}</ref> From then, physicians were clearly separated from the surgeons and barbers. Later, the role of the barbers was defined by the [[:fr:Confrérie de Saint-Côme et de Saint-Damien|College de Saint-Côme et Saint-Damien]], established by [[Jean Pitard]] in Paris circa 1210,<ref>{{cite book |last1=Quesnay |first1=François |last2=Bellial des Vertus |first2=François |title=Histoire de l'origine et des progrès de la chirurgie en France |year=1749 |location=Paris |publisher=Ganeau |url=http://www.bium.univ-paris5.fr/histmed/medica/cote?20729 |page=41 |language=fr |trans-title=History of the Origin and Progress of Surgery in France}}</ref> as academic surgeons of the long robe and [[barber surgeons]] of the short robe.

In [[Renaissance]]-era [[Amsterdam]], the surgeons used the colored stripes to indicate that they were prepared to [[Bloodletting|bleed]] their patients (red), set bones or pull teeth (white), or give a shave if nothing more urgent was needed (blue).<ref>{{cite book |last=Wallace |first=Robert |title=The World of Rembrandt: 1606–1669 |url=https://archive.org/details/worldofrembrandt00wall |url-access=registration |date=1968 |publisher=Time-Life Books |location=New York |page=[https://archive.org/details/worldofrembrandt00wall/page/62 62]}}</ref>

After the formation of the [[Worshipful Company of Barbers|United Barber Surgeon's Company]] in [[England]], a [[statute]] required the barber to use a red and white pole and the surgeon to use a red pole. In the [[Kingdom of France]], surgeons used a red pole with a basin attached to identify their offices. Blue often appears on poles in the [[United States]], possibly as a homage to its national colors. Another, more fanciful interpretation of these barber pole colors is that red represents [[arterial]] blood, blue is symbolic of [[venous]] blood, and white depicts the bandage.<ref>{{Cite web |url=http://www.history.com/news/ask-history/why-are-barber-poles-red-white-and-blue |title=Why are barber poles red, white and blue? |last=Nix |first=Elizabeth |website=History.com |date=2014-06-25 |access-date=2017-01-15}}</ref>

=== Manufacture of barber poles ===

Prior to 1950, there were four manufacturers of barber poles in the United States. In 1950, [[William Marvy]] of [[St. Paul, Minnesota]], started manufacturing barber poles. Marvy made his 50,000th barber pole in 1967, and, by 2010, over 82,000 had been produced.<ref>{{cite web|url=http://www.wmmarvyco.com/fr_about.htm/ |title=About Us |publisher=William Marvy Company |year=2010 |access-date=14 November 2010 |url-status=dead |archive-url=https://web.archive.org/web/20111114142423/http://www.wmmarvyco.com/fr_about.htm |archive-date=14 November 2011 }}</ref> The William Marvy Company is now the sole manufacturer of barber poles in North America, and sells only 500 per year (compared to 5,100 in the 1960s).<ref name="last">{{cite news|first=Annalyn |last=Censky |year=2007 |url=https://money.cnn.com/galleries/2010/smallbusiness/1004/gallery.last_one_standing/index.html |title=Last of Their Kind: From Barber Poles to Limburger Cheese, These 5 Companies are the Last Left in America Making Iconic Products now in their Twilight. |publisher=[[CNNMoney.com]] |access-date=14 November 2010 |archive-url=https://web.archive.org/web/20101011183310/https://money.cnn.com/galleries/2010/smallbusiness/1004/gallery.last_one_standing/index.html |archive-date=11 October 2010 |url-status=live |df=dmy }}</ref> In recent years, the sale of spinning barber poles has dropped considerably, since few barber shops are opening, and many jurisdictions prohibit moving signs. Koken of [[St. Louis, Missouri]], manufactured barber equipment such as chairs and assorted poles in the 19th century.

The barber pole used to indicate the practice of a "barber-surgeon" who also performed [[dental extraction|tooth extraction]], [[cupping therapy|cupping]], [[leech]]ing, [[bloodletting]], [[enema]]s, [[amputation]]s, etc. Today's barber poles represent only barbershops where hair is cut and beards are shaved.<ref>{{cite web|url=http://www.barber-schools.org/barber-information/history-of-the-barber|title=History of the Barber - Barber Schools|work=barber-schools.org|date=8 March 2012 }}</ref> As early as 1905, use of the poles was reported to be "diminishing" in the United States.<ref name="Tunis">{{cite book |url=https://books.google.com/books?id=TV-Y4QD-IaoC&q=barber+pole+tails&pg=PA42 |last=Tunis, Edwin. |title=Colonial Craftsmen and the Beginnings of American Industry |page=42 |place=Cleveland and New York |publisher=World Publishing |year=1905 |access-date=14 November 2010 |isbn=978-0-8018-6228-1}}</ref>

Barber poles have become a topic of controversy in the hairstyling business. In some American states, such as [[Michigan]] in March 2012, legislation has emerged proposing that barber poles should only be permitted outside barbershops, but not traditional beauty salons. Barbers and cosmetologists have engaged in several legal battles claiming the right to use the barber pole symbol to indicate to potential customers that the business offers haircutting services. Barbers claim that they are entitled to exclusive rights to use the barber pole because of the tradition tied to the craft, whereas [[cosmetologist]]s think that they are equally capable of cutting men's hair (though many cosmetologists are not permitted to use [[razor]]s, depending on their state's laws).<ref>{{cite web|url=http://www.barber-schools.org/blog/banning-barber-poles-at-michigan-salons|title=Banning Barber Poles at Michigan Salons? - Barber Schools|work=barber-schools.org|date=26 March 2012 }}</ref>

The term ''on the barber pole'' or ''keep it on the barber pole'' is pilot jargon that refers to flying an aircraft at the maximum safe velocity. The [[airspeed Indicator]] on aircraft capable of flying at altitude features a red/white striped needle resembling a barber pole. This needle displays the V<sub>''MO''</sub> (Maximum Operating Velocity) or—at altitude—the M<sub>''MO''</sub> ([[Mach Number|Mach]] Limit Maximum Operating Speed) of the aircraft.<ref name="McGraw">{{cite web |url=http://www.answers.com/topic/barber-s-pole-2 |title=McGraw Hill Dictionary of Aviation |publisher=McGraw Hill |work=Answers.com |access-date=28 December 2010}}</ref> This needle also indicates the maximum operating Mach number above the VMO/MMO changeover level. As the aircraft increases in altitude and the air decreases in density and temperature, the speed of sound also decreases. Close to the speed of sound, an aircraft becomes susceptible to [[buffeting]] caused by shock waves produced by flying at [[transonic]] speeds. Thus, as the speed of sound decreases, so the maximum safe operating speed of the aircraft is reduced. The "barber pole" needle moves to indicate this speed. Flying "on the barber pole" therefore means to be flying the aircraft as fast as is safe to do so in the current conditions.<ref>{{cite web |url=http://www.aviationshop.com.au/avfacts/sample_nav.htm#asi |title=The Conventional Airspeed Indicator |last=Avery |first=Rob |access-date=14 November 2010 |archive-url=https://web.archive.org/web/20100504101717/http://www.aviationshop.com.au/avfacts/sample_nav.htm#asi |archive-date=4 May 2010 |url-status=dead }}</ref>

''Barberpole'' is a phrase used to describe the striped output of indicators used during the [[Apollo Program|Apollo]] and [[Space Shuttle program|Shuttle]] programs. Typically an indicator was positioned below a switch. When the switch was activated and the activation indeed performed, the resulted activation was talked back via a separated electrical line to the barberpole indicator to show a grey and white striped pattern, thus verifying the action to the astronaut. Such switches with barberpole indicators were called ''talkback switches''. Various indicators in the Apollo Command Modules indicated barberpole when the corresponding system was inactive. Astronaut [[Jim Lovell]] can also be found describing system indications as "barber poled" in the transcript of radio transmissions during the [[Apollo 13#Explosion|Apollo 13 accident]].<ref>{{cite web |url=https://history.nasa.gov/Timeline/apollo13chron.html |title=Detailed Chronology of Events Surrounding the Apollo 13 Accident |date=17 June 2011 |access-date=20 March 2016}}</ref>

==== Meteorology ====
* According to the [[National Oceanic and Atmospheric Administration]], ''barber pole'' is a slang term used by [[weather spotters|weather]] and [[storm spotters]] to describe "a [[thunderstorm]] [[updraft]] with a visual appearance including cloud [[:wikt:striation|striations]] that are curved in a manner similar to the stripes of a barber pole.

=== Booksellers ===
Red or [[rubric]] posts were sometimes used by [[booksellers]] in England prior to 1800. William Roberts reports in ''The Book Hunter in London'' that certain 18th-century bookshops in the Little Britain district of London sported such poles:
<blockquote>A few years before Nichols published [in 1816] his ''Literary Anecdotes'', two booksellers used to sport their rubric posts close to each other here in Little Britain, and these rubric posts were once as much the type of a bookseller's shop as the pole is of a barber's&nbsp;... Sewell, Cornhill, and Kecket and De Hondt, Strand, were among the last to use these curious trade signs.<ref>{{cite book |last=Roberts |first=William |title= The Book-Hunter in London: Historical and Other Studies of Collectors and Collecting |year=1895 |publisher=Elliot Stock |page=176 |url=http://www.gutenberg.org/ebooks/22607 |location=London |access-date=14 November 2010}}</ref></blockquote>

* The [[41 Combat Engineer Regiment]], a part of the [[Canadian Military Engineers]], produced and delivered over 16,000 distinctive barber pole lane markers during World War II.{{cn|date=December 2024}}

=== Canadian Naval group ===
The famous [[Barber Pole Group]] was originally a group of 120 [[Flower-class corvette]]s built in Canada during World War II, and charged primarily with protecting freighter [[convoy]]s. The original group was Escort Group C-3.

=== Hockey ===
[[File:Bruce Stuart.jpg|thumb|right|200px|alt=Brown-haired man in jersey of vertical red, black and white stripes|Ottawa Senators [[Bruce Stuart]] in 1909–10 jersey]]
* In the 1896–97 season, the [[Ottawa Senators (original)|Ottawa Senators]] first adopted the "barber pole" design for their [[hockey jersey]], with which the team became identified. The design featured strong horizontal stripes of red, black and white; white pants; and red, white and black striped stockings. This basic design would be used for the rest of the organization's existence, except for the 1909–1910 season. In that season, the stripes were vertical and Montreal fans nicknamed the team derisively as ''les suisses'', a slang term for [[chipmunk]].<ref>Kitchen (2008), p. 167</ref> In the [[1929–30 Ottawa Senators season|1929–30 season]], the club added the "O" logo to the chest of the jersey.<ref>Kitchen (2008), p. 303</ref> The "barber-pole" uniform was later adopted by the [[Ottawa 67's]] junior hockey team.

* In the 1920s and 1930s, beginning in the 1927–28 season, the Senators, [[Boston Bruins]], [[Montreal Maroons]], [[Chicago Blackhawks]], [[History of the Detroit Red Wings|Detroit Cougars]], and [[Toronto Maple Leafs]] had a barber's pole variation in their jerseys. Meanwhile, the [[New York Americans]], wore "basically ... the United States flag as a jersey." The style endured, but in the 1938–39 season, the Blackhawks were the last to have a barber pole jersey in the traditional sense. The Hawks retired their barber pole at the end of the 1954–55 season.<ref name="Canadiens" />
* In junior ranks, the [[Chicoutimi Saguenéens]] and the [[Ottawa 67's]] use them in the [[Quebec Major Junior Hockey League]] (QMJHL) and Ontario Hockey League (OHL). During their existence in the [[Pacific Coast Hockey Association]], the [[Seattle Metropolitans]] wore a red/white/green striped design: this has occasionally been brought back by the [[Seattle Thunderbirds]] of the [[Western Hockey League]] (WHL) to honor the history of hockey in the city.
* The style remained dormant until the [[National Hockey League]]'s 75th anniversary, when Chicago wore replicas of their barber-pole sweaters as part of the league's celebrations. Since then, Montreal has also worn barber-pole replicas during their centenary season, and the design has become popular with amateur teams. See [[NHL uniform]] and [[Throwback uniform]].
